Ch 6 The Muscular System Notes Ch 6 the muscular system notes. lisa peck. muscular system: consists of skeletal muscles and their connective tissue attachments. organ skeletal muscle. consists of hundreds of muscle fibers (cells) bound tog. by connective tissue. cell muscle fibers elongated cells. Muscular system. chapter 6 (part 2) the five golden rules of skeletal muscle activity: with a few exceptions, all the skeletal muscles cross at least one joint. typically, the bulk of a skeletal muscle lies proximal to the joint crossed. all skeletal muscles have a least two attachments: the origin and the insertion.
Chapter 6 The Muscular System Chapter 6 The Muscular System M Chapter 6: the muscular system i. introduction to the muscular system. a. definition of the muscular system: the muscular system is the body system composed of skeletal, smooth, and cardiac muscles that allow for movement and bodily functions. Effect of exercise on muscles. exercise increases muscle size, strength, and endurance. aerobic (endurance) exercise (biking, jogging) results in stronger, more flexible muscles with greater resistance to fatigue. increases blood supply, increase in number of mitochondria, & ability to store o2. Chapter 6: the muscular system 1. muscles are responsible for all types of body movement. 2. three basic muscle types are found in the body: a. b. c. 3. characteristics of muscles a. & muscle cells are elongated (muscle cell = muscle fiber) b. of muscles is due to the movement of c. Released from the distal end of a motor neuron axon and stimulates a skeletal muscle fiber. acetylcholine causes the muscle fiber to conduct an impulse over the surface of the fiber that reaches deep within the fiber through the transverse tubules. a muscle impulse signals the sarcoplasmic reticulum to release calcium ions.

The muscular system • muscles are responsible for all movement of the body • there are three basic types of muscle – skeletal – cardiac – smooth. 5. info about muscles • only body tissue able to contract • create movement by flexing and extending joints • body energy converters (many muscle cells contain many mitochondria) 6. 3. Ch muscular system the muscular system is composed of all the muscles in the body and works in coordination with the skeletal and nervous systems. muscular development in newborns and infants progresses from heat to foot. muscles provide the mechanism for movement of the body and locomotion from one place to another. muscles produce heat and help the body maintain posture and stability. there.
