MUSCLE PHYSIOLOGY

Detailed explanation-1: -Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control.

Detailed explanation-2: -Cardiac muscle: It is also striated but involuntary. They make the heart which pumps blood in our body our whole life.

Detailed explanation-3: -Cardiac muscle comprises the heart, which pumps blood through the vasculature. Skeletal and cardiac muscles are known as striated muscles, because the filaments of actin and myosin that power their contraction are organized into repeating arrays, called sarcomeres, that have a striated microscopic appearance.

Detailed explanation-4: -Striated muscles are highly organized tissues (Fig. 1) that convert chemical energy to physical work. The primary function of striated muscles is to generate force and contract in order to support respiration, locomotion, and posture (skeletal muscle) and to pump blood throughout the body (cardiac muscle).

Detailed explanation-5: -Involuntary muscles, also known as “white muscles” or “smooth muscles”, are muscles in the human body whose contraction is controlled by the autonomic nervous system. Involuntary muscles include all muscles whose activity is independent and not affected by voluntary nerve activity.
