Hand Anatomy Bones

The palm includes five metacarpals and each finger except the thumb contains one proximal phalanx one middle phalanx and one distal phalanx. Each finger has three phalanges.

Normal Anatomy Of The Carpal Bones Diagram Of The Wrist

The heel of the hand is the area anteriorly to the bases of the metacarpal bones.

Hand anatomy bones. There are three phalanges in each finger. Besides all scaphoid is the most commonly fractured bone in the hand. The wrist is a complex mechanical system of 8 small bones known as the carpal bones.

The wrist links the hand to the arm. Anatomy of the hand and wrist. Carpal bones proximal a set of eight irregularly shaped 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. Each hand consists of 19 bones. Phalanges distal the bones of the fingers.

Bones muscles tendons nerves. We use our hands in performing so many minor as well as major. The hand is innervated by the median ulnar and radial nerves each of which has sensory and motor components.

These are located in the wrist area. A proximal phalanx articulates with the first metacarpal and a distal phalanx forms the tip of the thumb. One row connects with the ends of the bones in the forearm radius and ulna.

The finger and thumb bones are called the phalanges. 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. These hand bones are five in number with each one of them relating to some digit.

Areas of the human hand include. The palm volar which is the central region of the anterior part of the hand. However the intrinsic muscles of the hand are only partially responsible for all its range of motion.

Each thumb has two phalanges. Metacarpals there are five metacarpals each one related to a digit. Hand bones hand bones anatomy and structure.

The opisthenar area dorsal is the corresponding area on the posterior part of the hand. Each hand contains 27 distinct bones that give the hand an incredible range and precision of motion. The carpal bones are arranged in 2 interrelated rows.

They can be divided into three categories. The phalanges are fairly simple bones. The proximal phalanx is the largest of the three bones in each finger.

The rest of the fingers have three phalanges each. The hand itself consists of specific bones onto which various muscles are attached and a collection of neurovascular structures responsible for drainage and innervation. The forearms ulna and radius support the many muscles that manipulate the bones of the hand and wrist.

The bones of the hand and wrist provide the body with support and flexibility to manipulate objects in many different ways. Proximal middle and distal phalanges.
