A reliable way of identifying human hands is from the presence of opposable thumbs. Opposable thumbs are identified by the ability to be brought opposite to the fingers, a muscle action known as opposition.

The skeleton of the human hand consists of 27 bones: [10] the eight short carpal bones of the wrist are organized into a proximal row scaphoid , lunate , triquetral and pisiform which articulates with the bones of the forearm, and a distal row trapezium , trapezoid , capitate and hamate , which articulates with the bases of the five metacarpal bones of the hand.

The heads of the metacarpals will each in turn articulate with the bases of the proximal phalanx of the fingers and thumb.

These articulations with the fingers are the metacarpophalangeal joints known as the knuckles. At the palmar aspect of the first metacarpophalangeal joints are small, almost spherical bones called the sesamoid bones.

The fourteen phalanges make up the fingers and thumb, and are numbered I-V thumb to little finger when the hand is viewed from an anatomical position palm up.

The four fingers each consist of three phalanx bones: proximal, middle, and distal. The thumb only consists of a proximal and distal phalanx. Because supination and pronation rotation about the axis of the forearm are added to the two axes of movements of the wrist, the ulna and radius are sometimes considered part of the skeleton of the hand.

There are numerous sesamoid bones in the hand, small ossified nodes embedded in tendons; the exact number varies between people: [7] whereas a pair of sesamoid bones are found at virtually all thumb metacarpophalangeal joints, sesamoid bones are also common at the interphalangeal joint of the thumb In rare cases, sesamoid bones have been found in all the metacarpophalangeal joints and all distal interphalangeal joints except that of the long finger.

The fixed and mobile parts of the hand adapt to various everyday tasks by forming bony arches: longitudinal arches the rays formed by the finger bones and their associated metacarpal bones , transverse arches formed by the carpal bones and distal ends of the metacarpal bones , and oblique arches between the thumb and four fingers :.

Of the longitudinal arches or rays of the hand, that of the thumb is the most mobile and the least longitudinal. While the ray formed by the little finger and its associated metacarpal bone still offers some mobility, the remaining rays are firmly rigid.

The phalangeal joints of the index finger, however, offer some independence to its finger, due to the arrangement of its flexor and extension tendons.

The carpal bones form two transversal rows, each forming an arch concave on the palmar side. Because the proximal arch simultaneously has to adapt to the articular surface of the radius and to the distal carpal row, it is by necessity flexible.

In contrast, the capitate, the "keystone" of the distal arch, moves together with the metacarpal bones and the distal arch is therefore rigid.

The stability of these arches is more dependent of the ligaments and capsules of the wrist than of the interlocking shapes of the carpal bones, and the wrist is therefore more stable in flexion than in extension.

The ligaments that maintain the distal carpal arches are the transverse carpal ligament and the intercarpal ligaments also oriented transversally.

These ligaments also form the carpal tunnel and contribute to the deep and superficial palmar arches. Several muscle tendons attaching to the TCL and the distal carpals also contribute to maintaining the carpal arch.

Compared to the carpal arches, the arch formed by the distal ends of the metacarpal bones is flexible due to the mobility of the peripheral metacarpals thumb and little finger.

As these two metacarpals approach each other, the palmar gutter deepens. The central-most metacarpal middle finger is the most rigid. It and its two neighbors are tied to the carpus by the interlocking shapes of the metacarpal bones.

The thumb metacarpal only articulates with the trapezium and is therefore completely independent, while the fifth metacarpal little finger is semi-independent with the fourth metacarpal ring finger which forms a transitional element to the fifth metacarpal.

Together with the thumb, the four fingers form four oblique arches, of which the arch of the index finger functionally is the most important, especially for precision grip, while the arch of the little finger contribute an important locking mechanism for power grip.

The thumb is undoubtedly the "master digit" of the hand, giving value to all the other fingers. Together with the index and middle finger, it forms the dynamic tridactyl configuration responsible for most grips not requiring force.

The ring and little fingers are more static, a reserve ready to interact with the palm when great force is needed. The muscles acting on the hand can be subdivided into two groups: the extrinsic and intrinsic muscle groups.

The extrinsic muscle groups are the long flexors and extensors. They are called extrinsic because the muscle belly is located on the forearm. The intrinsic muscle groups are the thenar thumb and hypothenar little finger muscles; the interosseous muscles four dorsally and three volarly originating between the metacarpal bones; and the lumbrical muscles arising from the deep flexor and are special because they have no bony origin to insert on the dorsal extensor hood mechanism.

The fingers have two long flexors, located on the underside of the forearm. They insert by tendons to the phalanges of the fingers. The deep flexor attaches to the distal phalanx, and the superficial flexor attaches to the middle phalanx.

The flexors allow for the actual bending of the fingers. The thumb has one long flexor and a short flexor in the thenar muscle group. The human thumb also has other muscles in the thenar group opponens and abductor brevis muscle , moving the thumb in opposition, making grasping possible.

The extensors are located on the back of the forearm and are connected in a more complex way than the flexors to the dorsum of the fingers.

The tendons unite with the interosseous and lumbrical muscles to form the extensorhood mechanism. The primary function of the extensors is to straighten out the digits.

The thumb has two extensors in the forearm; the tendons of these form the anatomical snuff box. Also, the index finger and the little finger have an extra extensor used, for instance, for pointing.

The extensors are situated within 6 separate compartments. The first four compartments are located in the grooves present on the dorsum of inferior side of radius while the 5th compartment is in between radius and ulna.

The 6th compartment is in the groove on the dorsum of inferior side of ulna. The hand is innervated by the radial , median , and ulnar nerves.

The radial nerve supplies the finger extensors and the thumb abductor , thus the muscles that extends at the wrist and metacarpophalangeal joints knuckles ; and that abducts and extends the thumb.

The median nerve supplies the flexors of the wrist and digits, the abductors and opponens of the thumb, the first and second lumbrical.

The ulnar nerve supplies the remaining intrinsic muscles of the hand. All muscles of the hand are innervated by the brachial plexus C5—T1 and can be classified by innervation: [16].

The radial nerve supplies the skin on the back of the hand from the thumb to the ring finger and the dorsal aspects of the index, middle, and half ring fingers as far as the proximal interphalangeal joints.

The median nerve supplies the palmar side of the thumb, index, middle, and half ring fingers. Dorsal branches innervates the distal phalanges of the index, middle, and half ring fingers.

The ulnar nerve supplies the ulnar third of the hand, both at the palm and the back of the hand, and the little and half ring fingers. There is a considerable variation to this general pattern, except for the little finger and volar surface of the index finger.

For example, in some individuals, the ulnar nerve supplies the entire ring finger and the ulnar side of the middle finger, whilst, in others, the median nerve supplies the entire ring finger.

The glabrous hairless skin on the front of the hand, the palm, is relatively thick and can be bent along the hand's flexure lines where the skin is tightly bound to the underlying tissue and bones.

Indeed, genes specifically expressed in the dermis of palmoplantar skin inhibit melanin production and thus the ability to tan , and promote the thickening of the stratum lucidum and stratum corneum layers of the epidermis.

All parts of the skin involved in grasping are covered by papillary ridges fingerprints acting as friction pads.

In contrast, the hairy skin on the dorsal side is thin, soft, and pliable, so that the skin can recoil when the fingers are stretched.

The web of the hand is a "fold of skin which connects the digits". They are defined as "one of the folds of skin, or rudimentary web, between the fingers and toes".

The ratio of the length of the index finger to the length of the ring finger in adults is affected by the level of exposure to male sex hormones of the embryo in utero.

This digit ratio is below 1 for both sexes but it is lower in males than in females on average. A number of genetic disorders affect the hand.

Polydactyly is the presence of more than the usual number of fingers. One of the disorders that can cause this is Catel-Manzke syndrome.

The fingers may be fused in a disorder known as syndactyly. Or there may be an absence of one or more central fingers—a condition known as ectrodactyly.

Additionally, some people are born without one or both hands amelia. Hereditary multiple exostoses of the forearm—also known as hereditary multiple osteochondromas—is another cause of hand and forearm deformity in children and adults.

There are several cutaneous conditions that can affect the hand including the nails. The autoimmune disease rheumatoid arthritis can affect the hand, particularly the joints of the fingers.

Some conditions can be treated by hand surgery. These include carpal tunnel syndrome , a painful condition of the hand and fingers caused by compression of the median nerve , and Dupuytren's contracture , a condition in which fingers bend towards the palm and cannot be straightened.

Similarly, injury to the ulnar nerve may result in a condition in which some of the fingers cannot be flexed. A common fracture of the hand is a scaphoid fracture —a fracture of the scaphoid bone , one of the carpal bones.

This is the commonest carpal bone fracture and can be slow to heal due to a limited blood flow to the bone. There are various types of fracture to the base of the thumb; these are known as Rolando fractures , Bennet's fracture , and Gamekeeper's thumb.

Another common fracture, known as Boxer's fracture , is to the neck of a metacarpal. This development has been accompanied by important changes in the brain and the relocation of the eyes to the front of the face, together allowing the muscle control and stereoscopic vision necessary for controlled grasping.

This grasping, also known as power grip, is supplemented by the precision grip between the thumb and the distal finger pads made possible by the opposable thumbs.

Hominidae great apes including humans acquired an erect bipedal posture about 3. While the human hand has unique anatomical features, including a longer thumb and fingers that can be controlled individually to a higher degree, the hands of other primates are anatomically similar and the dexterity of the human hand can not be explained solely on anatomical factors.

The neural machinery underlying hand movements is a major contributing factor; primates have evolved direct connections between neurons in cortical motor areas and spinal motoneurons , giving the cerebral cortex monosynaptic control over the motoneurons of the hand muscles; placing the hands "closer" to the brain.

There are nevertheless several primitive features left in the human hand, including pentadactyly having five fingers , the hairless skin of the palm and fingers, and the os centrale found in human embryos, prosimians, and apes.

Furthermore, the precursors of the intrinsic muscles of the hand are present in the earliest fishes, reflecting that the hand evolved from the pectoral fin and thus is much older than the arm in evolutionary terms.

The proportions of the human hand are plesiomorphic shared by both ancestors and extant primate species ; the elongated thumbs and short hands more closely resemble the hand proportions of Miocene apes than those of extant primates.

This suggests that the derived changes in modern humans and Neanderthals did not evolve until 2. In humans, the big toe is thus more derived than the thumb.

There is a hypothesis suggesting the form of the modern human hand is especially conducive to the formation of a compact fist, presumably for fighting purposes.

The fist is compact and thus effective as a weapon. It also provides protection for the fingers. Static adult human physical characteristics of the hand.

However, making lifestyle changes and taking medications can help prevent flare-ups and reduce their severity.

Treating any underlying conditions can also help. Arthritis is a general term for more than different disorders that cause pain, swelling, and stiffness in joints.

The most common type of arthritis is osteoarthritis, which occurs when the cartilage that protects a joint wears away over time.

This wear and tear allows the bones in the joint to rub against each other, causing pain and stiffness. Over time, this inflammation can lead to permanent joint damage.

Arthritis can affect any joint in the body, including in the hands and wrists. Treatment depends on the type of arthritis, but it can include making lifestyle changes, taking medications, exercising, and seeking physical therapy or occupational therapy.

Carpal tunnel syndrome occurs when the median nerve, which runs through the wrist, becomes compressed or squeezed. Symptoms can start gradually and are often worse at night.

They typically include pain, tingling, and numbness in the hand and arm. Carpal tunnel syndrome can also cause weakness in the affected hand. Some people may experience a loss of proprioception, which is a sense of where the hand is in space.

This condition can get worse with time, so early diagnosis and treatment is important. Treatment options include:.

Osteoporosis is the gradual loss of bone mass, which causes the bones to become weak and brittle.

Osteoporosis tends to develop slowly and is more common in females and older people. RICE therapy can help with a range of minor injuries, including hand and wrist pain.

RICE stands for rest, ice, compression, and elevation:. There are many possible causes of hand pain. They range from injuries and overuse to degenerative conditions such as arthritis.

Tennis elbow is a repetitive strain injury in the forearm. A person can usually treat it at home with rest and over-the-counter medication.
