It is controlled by the central nervous system, which sends out an assortment of signals to keep the body running smoothly. Similar to skeletal muscle, cardiac muscle is striated and organized into sarcomeres, possessing the same banding organization as skeletal muscle (see Figure 17.1). Skeletal muscles contribute to the maintenance of homeostasis in the body by generating heat.Â This heat is very noticeable during exercise, when sustained muscle movement causes body temperature to rise, and in cases of extreme cold, when shivering produces random skeletal muscle contractions to generate heat. [sup] Depending on the area of the brain that is affected, signs and symptoms will vary in the type and severity between individuals. Start over; Their origin and definition related to Muscles.

This is done through muscle contraction where the trunk is kept straight either when sitting or standing. All three muscle tissues have some properties in common; they all exhibit a quality called excitability as their plasma membranes can change their electrical states (from polarized to depolarized) and send an electrical wave called an action potential along the entire length of the membrane. The body contains three types of muscle tissue: skeletal muscleno post, cardiac muscleno post, and smooth muscleno postÂ (see Figure 17.1). biological process that results in stable equilibrium.
