A finger is a type of digit and a manipulating and sensory organ found in the hands of humans and other primates. Phalanges are the five digits on each hand that humans have. Some people, however, have more or less than five fingers due to congenital disorders like polydactyly or oligodactyly or accidental or surgical amputations. The index, middle, and ring fingers, as well as the little finger or pinkie, are the first digits. Depending on the definition, the thumb might be considered a finger or not.

According to English dictionaries, one of the five digits, including the thumb, or one of the four digits, excluding the thumb (in which case they are numbered from 1 to 4 starting with the index finger closest to the thumb).

On one of the sides, the thumb (which is connected to the trapezium) is parallel to the arm.

The palm has five metacarpal bones, one for each of the five digits. The human hand has fourteen digital bones, sometimes called phalanges or phalanx bones: two in the thumb (no middle phalanx) and three in each of the four fingers. The three phalanxes are the distal phalanx, which bears the nail, the middle phalanx, and the proximal phalanx.

Sesamoid bones are small ossified nodes placed in tendons to provide extra leverage and reduce pressure on the surrounding tissue. Many are located on the palm around the base of the fingers; the exact quantity varies from person to person.

Metacarpophalangeal joints attach the phalanges to the metacarpal bones, whereas interphalangeal articulations join the phalanges to the metacarpal bones.


Each finger may flex, extend, abduct, adduct, and circumduct in addition to flexing, extending, abducting, and adducting. The most forceful movement is flexion. In humans, each finger is flexed by two main muscles, with additional muscles assisting the process. Despite the fact that the muscle bulks that move each finger are partially blended, and the tendons are linked by a net of fibrous tissue, restricting completely free mobility, each finger may move independently of the others.

The fingertips do not have any muscles (other than arrector pili). The muscles that move the finger joints are found in the palm and forearm. The long tendons that transmit motion from the forearm muscles may be seen moving under the skin at the wrist and on the back of the hand.

The muscles of the fingers are made up of extrinsic and intrinsic muscles. Extrinsic muscles include the long flexors and extensors. They’re called extrinsic because the muscular belly is on the forearm.

The fingers have two long flexors on the underside of the forearm. Tendons connect them to the phalanges of the fingers. The middle phalanx is connected to the superficial flexor, whereas the distal phalanx is connected to the deep flexor. The muscles that allow the fingers to bend are known as flexors. The thumb has one long flexor and one short flexor in the thenar muscle group. The thenar group of muscles in the human thumb (opponents and adductor brevis muscles) allows grasping by moving the thumb in opposition.
