MEDICAL PHYSIOLOGY

Detailed explanation-1: -The ligaments are fibrous tissues that help bind together the joints in the hand. The sheaths are tubular structures that surround part of the fingers. The tendons connect muscles in the arm or hand to the bone to allow movement.

Detailed explanation-2: -At fibrous entheses, the tendon or ligament attaches either directly to the bone or indirectly to it via the periosteum. In both cases, dense fibrous connective tissue connects the tendon/ligament to the periosteum and there is no evidence of (fibro)cartilage differentiation (Fig.

Detailed explanation-3: -Important ligaments of the hand are: collateral ligaments – strong ligaments on either side of the finger and thumb joints, which prevent sideways movement of the joint. volar plate – a ligament that connects the proximal phalanx to the middle phalanx on the palm side of the joint.

Detailed explanation-4: -A joint is the part of the body where two or more bones meet to allow movement. Generally speaking, the greater the range of movement, the higher the risk of injury because the strength of the joint is reduced. The six types of freely movable joint include ball and socket, saddle, hinge, condyloid, pivot and gliding.

Detailed explanation-5: -Interossei (dorsal and palmar) The interossei muscles begin between the bones of the hand. Hypothenar. Thenar. Lumbricals. Adductor Pollicis. Abductor pollicis longus. Biceps. Brachialis. More items
