Anatomy Of The Hand Bones

The wrist links the hand to the arm. Shaped like a little boat.

Human Hand Bones Anatomy

Bones muscles tendons nerves.

Anatomy of the hand bones. The hand itself consists of specific bones onto which various muscles are attached and a collection of neurovascular structures responsible for drainage and innervation. Following are the carpal bones in the first row starting from the lateral side same side as your thumb right next to the radius and working across. The wrist is a complex mechanical system of 8 small bones known as the carpal bones.

Each hand contains 27 distinct bones that give the hand an incredible range and precision of motion. The bones of the hand and wrist can be broken down into 14 phalanges 5 metacarpals and 8 carpals. The thumb has only a proximal and distal phalanx.

The distal ends of the radius and ulna bones articulate with the hand bones at the junction of the wrist which is formally known as the carpus. The bones of the hand. The forearms ulna and radius support the many muscles that manipulate the bones of the hand and wrist.

However the intrinsic muscles of the hand are only partially responsible for all its range of motion. These hand bones are five in number with each one of them relating to some digit. Besides all scaphoid is the most commonly fractured bone in the hand.

Shaped like a pyramid. Hand bones hand bones anatomy and structure. It opposes the tips of the other fingers and is essential for precision grip.

Has a scaphoid tubercle. Shaped like a crescent moon. These bones consist mostly of long bones except for the eight bones of the wrist called carpals which anatomists classify as short bones.

The bones of the hand and wrist provide the body with support and flexibility to manipulate objects in many different ways. We use our hands in performing so many minor as well as major. One row connects with the ends of the bones in the forearm radius and ulna.

The carpal bones are arranged in 2 interrelated rows. Pisiform a sesamoid bone formed within the tendon of the flexor carpi ulnaris. Anatomy of the hand and wrist.

The metacarpals articulate with the proximal phalanges which articulate with the middle phalanges which finally articulate with the distal phalanges.
