Question

Quizplus · Accepted Answer

Skeletal muscle contraction produces movements of the body. This is the primary function of skeletal muscle - to allow movement of the body and its parts.

Option A is incorrect because skeletal muscle contraction does not alter blood flow through the heart.

Option C is incorrect because skeletal muscles do not pump blood throughout the body - this is the role of the heart.

Option D is incorrect because flexion of a skeletal muscle causes movement of limbs towards the body, not away from it.

Option E is incorrect because extensors are skeletal muscles that cause limbs to extend and move away from the body, not draw in towards it.
