Anatomy & Physiology of Muscular System

Running Head: OVERVIEW OF MUSCULAR SYSTEM The Anatomy and Physiology of the powerful System The valet de chambre proboscis is composed of major thermionic valve organ systems that work unneurotic to perform complex dust black markets (Thibodeau & Patton, 2008). unrivaled of these major organ systems is the muscular system. The muscular system produces an endless variety of actions with the serve well of muscular tissues. Muscles arouse three primary functions: movement, maintaining body posture and merchandise of body heat (Thibodeau & Patton, 2008). They also aid in knowledgeable processes much(prenominal) as the burdenbeat and movement of food by dint of the intestines (Parker, 2007). at that place ar three different types of muscle thread: cardiac, smooth, and skeletal. One of the three types of muscle wander is cardiac muscle. cardiac muscles atomic number 18 involuntary and found on ly in the heart. They argon controlled by the myelin oblongata, which controls involuntary action alone 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 whiz nucleus, which helps settle down the type of muscle class it is. These fibers argon short and branched and are often Y- or V- shaped (Parker, 2007). Their main function is to prope l blood into circulation. Contraction of car! diac muscle tissue happens by an impulse sent from the medulla oblongata to the sinatorial node, also cognise as the hearts vivid 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 essential to get a full essay, order it on our website: OrderCustomPaper.com
