Muscular System


**The function of the muscular system is to produce force, cause motion, strength, heat production, shock absorbtion, shaping the body, maintaining posture and respiration. **

** __More Info! __ An isotonic muscle contraction is an increase in muscular tension during movement without resistance (either lengthening or shortening), as in free opening and closing of the jaws. An Isometric muscle contractions An isometric contraction of a muscle generates force without changing length. **

__Different types of muscles:__ Smooth Muscles are involuntary non-striated muscle. Cardiac muscles are type of involuntary straited muscle found in the walls and histologic foundation of the heart. Skeletal muscles are is a form of straited muscle tissue existing under control of the somatic nervous system.

__Info about our system! __ The muscles recieve energy to function by composing special kinds of muscle fibers. While the fibers are made up of the similar kinds of cells, fluids, blood vessels, and nervous system components, muscle fibers have certain key physical distinctions that create two distinct kinds of fibers, fast-twitch (type II fibers) and slow-twitch. **

 The Muscular System provides shape, protects organs, and movement which leads to heat. It also helps contain the contol of blood vessles, airways and intestines, When the surroundings are cold, the body shivers to increase the body temperature. Hair erecile muscles also contracts to make our hairs stand to trap air, which is a good insulator of heat. **
 * __ How this system maintains homeostasis: __

__Connection with two other systems__: Muscles provide strength,balance,  posture, movement, and heat for the body to keep warm. The heart is a muscle and it pumps the blood through it constantly and in order to use the cardiovascular system, you need your muscles to function. The muscular system is related to the digestive system because it processes peristalsis to move the food through the body. It is essential for pumping blood through the body and plays a role in smooth muscles of the blood vessels to raise blood pressure during the stress response.Muscles help the body to have movement through the enviroment and inside the body for its processes.
