2 the wrist joint or radiocarpal joint the joint between the radius and the carpus and 3 the anatomical region surrounding the carpus including the distal parts of the bones of the forearm and the proximal parts of the metacarpus or five metacarpal bones and the series of joints between these bones thus referred to as wrist joints.

Anatomy term for wrist. Many structures vary slightly between people for example muscles that attach in slightly different places. Start studying anatomy terms. Hand wrist anatomy.

The wrist joint is distal to the elbow joint. Being subcutaneous bone you frequently have open fracture of this bone. Its formed as the wrist joint bends into a flexed position.

These terms are named after the radius and ulna bones in the forearm. The median and ulnar nerves are the major nerves of the hand running the length of the arm to transmit electrical impulses to and from the brain to create movement and sensation. Muscles contract to produce movement at joints where two or more bones meet.

In human anatomy the wrist is variously defined as 1 the carpus or carpal bones the complex of eight bones forming the proximal skeletal segment of the hand. The terms proximal and distal are used in structures that are considered to have a beginning and an end such as the upper limb lower limb and blood vessels. Another critical pair of terms used when describing sides of the hand or even wrist and forearm is radial and ulnar.

The anatomical term for this bone is tibia. Therefore the various terms of joint motion are beyond the scope of this reference. The two long bones of the forearm between the elbow and the wrist.

The two bones of the lower arm the radius and the ulna meet at the hand to form the wrist. They describe the position of a structure with reference to its origin proximal means closer to its origin distal means further away. Anatomical terms of movement are used to describe the actions of muscles on the skeleton.

This should help you to know if youve got the hang of this stuff. The term anatomical variation is used to refer to a difference in anatomical structures that is not regarded as a disease. Asked in human anatomy and physiology medical terminology.

Adduction of the wrist is also called ulnar deviation or ulnar flexion so as you can surmise joint motions are just as confusing as muscle names and perhaps more so. Start studying anatomical terminology.
