PPT-Muscle Contraction and the Sliding Filament Theory

Muscle Contraction and the Sliding Filament Theory Learning Objective To be able to explain the sliding filament theory using key terminology Structure of a Muscle Skeletal muscle is made up of bundles of muscle. Learning Objective:. To . be able to explain the sliding filament theory using appropriate terminology.. Structure of a Muscle. Skeletal muscle is made up of bundles of muscle . fibres. .. Fibres. are bound together by connective tissue through which run blood vessels and nerves.. Review Principles of Muscle Mechanics. Same principles apply to contraction of a single fiber and a whole muscle. Contraction produces tension, the force exerted on the load or object to be moved. Review Principles of Muscle Mechanics. . Contraction of Skeletal Muscle. . (fasicle). A. Muscle . Fiber. 1. . sarcolemma. . * muscle cell membrane . . * extends into muscle fiber (forms . T-tubules. ) . 2. . sarcoplasmic reticulum. Skeletal Muscle. Human body contains over 400 skeletal muscles. 40-50% of total body weight. Functions of skeletal muscle. Force production for locomotion and breathing. Force production for postural support. Foldable. You will make a Foldable to illustrate the steps in skeletal muscle contraction (use figure 10-1 on pg. 299). You may use any type of foldable (but only 1 colored sheet of paper). You may combine steps so you have less than the 10 steps on pg. 299. Types of Muscle. Skeletal – striated & voluntary. Smooth – involuntary. Cardiac - heart. The word “striated” means striped. Skeletal muscle appears striped under a microscope. . Muscles and Muscle Fiber. By BB. “Contraction in Action” Muscle Contraction Skits. Anatomy & Physiology/Tissues, Bones and Muscles. Purpose: . To create a live model or skit of approximately 3 minutes to demonstrate muscle anatomy and the physiology of muscle contraction.. Types of Muscle Tissue . (cont.). Muscle Group. Major Location. Major . Function. Mode of Control. Skeletal Muscle. Attached to bones and skin of the face. Produces body movements and facial expressions. I. Functions of Muscular Tissue. Like nervous tissue, muscles are excitable or "irritable”. they have the ability to respond to a stimulus. Unlike nerves, however, muscles are also:. Contractible. . pull. , not . push. . And it needs certain parts to do this.. Microscopic anatomy of muscle. The bits and pieces. Sarcolemma. – plasma membrane of a muscle cell. Myofibrils. – long ribbon-like organelles that take up the majority of the space in a muscle cell. Chapter 5: The Muscular System. The three major categories of muscle fibers are:. Skeletal . Smooth . Cardiac . Muscle Tissue. Skeletal Muscle (striated / voluntary muscle). Attached . to bones . and are largely .
