Hand Anatomy Bones

Hand bones hand bones anatomy and structure. There are three phalanges in each finger.

Anatomy Of Hand Bones

The proximal phalanx of the fingers is the proximal or first bone in the fingers when counting from the hand to the tip of the finger.

Hand anatomy bones. A total of 27 bones constitute the basic skeleton of the wrist and hand 8 carpals 5 metacarpals 14 phalanges 3 for each digit except thumb which has 2. Areas of the human hand include. Each hand consists of 19 bones.

Phalanges distal the bones of the fingers. These are located in the wrist area. Metacarpals there are five metacarpals each one related to a digit.

We use our hands in performing so many minor as well as major. Each finger has three phalanges. The opisthenar area dorsal is the corresponding area on the posterior part of the hand.

The rest of the fingers have three phalanges each. The palm volar which is the central region of the anterior part of the hand. The bones of the hand and wrist provide the body with support and flexibility to manipulate objects in many different ways.

Bones muscles tendons nerves. The hand itself consists of specific bones onto which various muscles are attached and a collection of neurovascular structures responsible for drainage and innervation. They can be divided into three categories.

The forearms ulna and radius support the many muscles that manipulate the bones of the hand and wrist. Each hand contains 27 distinct bones that give the hand an incredible range and precision of motion. However the intrinsic muscles of the hand are only partially responsible for all its range of motion.

A proximal phalanx articulates with the first metacarpal and a distal phalanx forms the tip of the thumb. The finger and thumb bones are called the phalanges. Each thumb has two phalanges.

The phalanges are fairly simple bones. The wrist links the hand to the arm. The proximal phalanx is the largest of the three bones in each finger.

These hand bones are five in number with each one of them relating to some digit. One row connects with the ends of the bones in the forearm radius and ulna. The wrist is a complex mechanical system of 8 small bones known as the carpal bones.

The heel of the hand is the area anteriorly to the bases of the metacarpal bones. Proximal middle and distal phalanges. The hand is innervated by the median ulnar and radial nerves each of which has sensory and motor components.

Anatomy of the hand and wrist. Besides all scaphoid is the most commonly fractured bone in the hand. Carpal bones proximal a set of eight irregularly shaped bones.

The palm includes five metacarpals and each finger except the thumb contains one proximal phalanx one middle phalanx and one distal phalanx. The carpal bones are arranged in 2 interrelated rows.
