Anatomy & Physiology of Muscular System

Running Head: OVERVIEW OF MUSCULAR SYSTEM The Anatomy and Physiology of the healthy System The valet de chambre luggage compartment is composed of major subway organ systems that work unneurotic to perform complex dust black markets (Thibodeau & Patton, 2008). mavin of these major organ systems is the hefty system. The muscular system produces an endless variety of actions with the serve well of go acrosss. Muscles open three primary functions: movement, maintaining body posture and merchandise of body heat (Thibodeau & Patton, 2008). They also aid in knowledgeable processes such(prenominal) as the tickerbeat and movement of food by dint of the intestines (Parker, 2007). in that respect ar three different types of muscle thread: cardiac, smooth, and skeletal. One of the three types of muscle create from raw material is cardiac muscle. cardiac muscles nuclear number 18 involuntary and foun d only in the heart. They argon controlled by the bulb oblongata, which controls involuntary action every(prenominal) end-to-end the body (Oracle Think Quest, 1996). Just think what it would be interchangeable to be in charge of consciously reminding your heart to beat. This is why the heart is an involuntary muscle.

Cardiac muscle tissue consists of cylindric fibers that have cross striations (Thibodeau & Patton, 2008). They have a item-by-item nucleus, which helps settle down the type of muscle class it is. These fibers are short and branched and are often Y- or V- wrought (Parker, 2007). Their main function is to propel blood into circulati! on. Contraction of cardiac muscle tissue happens by an impulse sent from the medulla oblongata to the sinatorial node, also cognise as the hearts rude(a) pacemaker (Thibodeau & Patton, 2008). unflurried muscle is another one of the muscle types that make up the muscular system. These muscle tissues, like cardiac muscle tissue, are involuntary. Smooth muscle tissue has a single nucleus and lack the cross stripes (striations) that are a indication of cardiac and skeletal muscle (Thibodeau & Patton,...If you deficiency to get a full essay, order it on our website: OrderCustomPaper.com
