MEDICAL PHYSIOLOGY

Detailed explanation-1: -The wrist joint also referred to as the radiocarpal joint is a condyloid synovial joint of the distal upper limb that connects and serves as a transition point between the forearm and hand. A condyloid joint is a modified ball and socket joint that allows for flexion, extension, abduction, and adduction movements.

Detailed explanation-2: -Condyloid joints, also known as ellipsoid joints, are composed of an egg-shaped bone known as a condyle that fits into a similarly shaped cavity. Although it sounds similar to a ball and socket joint, condyloid joints only allow for forward-backward and side to side movement and do not allow rotation.

Detailed explanation-3: -Radiocarpal joint and Metacarpo-phalangeal joint are examples of condyloid joints. An example of an Ellipsoid joint is the wrist; it functions similarly to the ball and socket joint except is unable to rotate 360 degrees; it prohibits axial rotation.

Detailed explanation-4: -An ellipsoid joint is a biaxial joint. An ellipsoid joint allows movements in all angular motions. The movement of ellipsoid joints is in two plains, back and front, and side to side. These joints are present between the knuckle joints, wrist joints, metacarpophalangeal joints and metatarsophalangeal joints of fingers.

Detailed explanation-5: -Examples of condyloid joints are The oval-shaped condyle of one bone fits into the elliptical cavity of the other bone. These joints allow biaxial movements-i.e., forward and backward, or from side to side, but not rotation. Radiocarpal joint and Metacarpo-phalangeal joint are examples of condyloid joints.
