MUSCLE PHYSIOLOGY

Detailed explanation-1: -The major functions of muscle tissues include promoting the movement of body structures, movement of blood throughout the body, stabilizing joints, and generating heat through contractions. However, storing fat is not a major function of the muscle tissues.

Detailed explanation-2: -Muscle is our primary storage site of glycogen (stored carbohydrate) and we can also store a small amount of fat in the muscle (intra-muscular triglycerides) along with a lot of water. A pound of fat contains somewhere around 3, 500 calories where a pound of muscle only contains about 600.

Detailed explanation-3: -Option D:production of body heat: The skeleton serves six major functions: support, movement, protection, production of blood cells, storage of minerals and endocrine regulations. Hence, production of body heat is not a function of the skeletal system. Thus, the answer is option D:Production of body heat.

Detailed explanation-4: -Muscles have a range of functions from pumping blood and supporting movement to lifting heavy weights or giving birth. Muscles work by either contracting or relaxing to cause movement. This movement may be voluntary (meaning the movement is made consciously) or done without our conscious awareness (involuntary).
