Hand And Finger Anatomy

The radial nerve the median nerve and the ulnar nerve. Understanding the basic anatomy of the hand and fingers is useful in understanding different types of finger injuries broken fingers and how some treatments differ from others.

Hand Wikipedia

A digit includes the hand bones but these bones are not separated into individual appendages like a finger.

Hand and finger anatomy. Anatomy of the fingers the human finger is mainly a bony structure with multiple joints giving it strength and flexibility. Each finger is made up of 3 phalanges. The bones of the hand palm are known as metacarpal bones.

14 phalanges which make up the fingers. This first joint at the base of the finger is called the metacarpophalangeal joint mcp. It works like a hinge when you straighten your fingers and thumb.

The thumb has two. These nerves carry signals from the brain to the muscles that move the arm hand fingers and thumb. Instead it is contained within a single structure the hand.

These 19 bones collectively form 14 separate joints. 5 elongated metacarpal bones which are next to the wrist and help to make up the palm. The metacarpals the five bones that comprise the middle part of the hand the phalanges singular phalanx the 14 narrow bones that make up the fingers of each hand.

The thumb is made up of 2. Each finger has three phalanges the distal middle and proximal. The largest joint of each finger lies between the finger and the hand.

All of the nerves that travel to the hand and fingers begin together at the shoulder. Each hand consists of 19 bones. All small carpal bones join the bones lying next to them and thus make the anatomy of the human hand very complex.

The hand is made up of many bones. Fingers are constructed of ligaments strong supportive tissue connecting bone to bone tendons attachment tissue from muscle to bone and three phalanges bones. 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.

Wrist palm and fingers are thus made up of several small joints. The thumb has no middle phalanx giving a total of 14 phalanges in each hand. The nerves also carry signals back to the brain about sensations such as touch pain and temperature.

Except for the thumb each finger has three phalanges the distal the bone on the tip of the finger middle and proximal the bone at the base of the finger phalanx. The palm includes five metacarpals and each finger except the thumb contains one proximal phalanx one middle phalanx and one distal phalanx. Joints are formed wherever two or more of these bones meet.

All five metacarpals together are recognized as the metacarpus.
