GROSS ANATOMY

Detailed explanation-1: -The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.

Detailed explanation-2: -Muscles move body parts by contracting and then relaxing. Muscles can pull bones, but they can’t push them back to the original position. So they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint.

Detailed explanation-3: -Skeletal Muscle These muscles are also controlled by the nervous system and the majority of skeletal muscles are attached to the bones of the body with tendons to enable bodily movement.

Detailed explanation-4: -Adduction is the moving of a body part toward the mid-line of the body. Abduction…is moving a body part away from the body. Flexion… Extension… Rotation… and last, rotation involves move a body part around an axis. 14-Sept-2015

Detailed explanation-5: -One of the most predominant characteristics of skeletal muscle tissue is its contractility and nearly all movement in the body is the result of muscle contraction. Four functions of muscle contraction are movement, posture, joint stability, and heat production. More items
