PPT-Skeletal Muscle Contraction

Neurotransmitter must stimulate muscle This happens at the neuromuscular junction Axon of neuron Synaptic bulb Muscle AcH Formed by Muscle fiber membrane The space synapse synaptic. 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. Muscles. Summation of Contractions. Figure 12-17a. Summation of Contractions. Figure 12-17b. Summation of Contractions. Figure 12-17c. Summation of Contractions. Figure 12-17d. Motor Units. Figure 12-18. 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.. . & . Reflexes, . Proprioception. and Movement. PSK 4U Unit 4, Day 4. Excitation. -. Contraction . Coupling. Muscles work by converting electrical and chemical energy into mechanical energy!. The process of muscle contraction as a whole is often referred to as “excitation-contraction coupling”. 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. As it contracts it . -causes movement. -maintains posture. -stabilizes joints. -and generates heat. . Muscle Types. Skeletal muscle (voluntary). muscle attached to the skeleton. cells are long, striated, and multinucleate. 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. . Muscular System. Part 1. Muscular Tissue . 3 types:. Skeletal. striated & voluntary. Cardiac. striated & involuntary. Smooth . Smooth & involuntary. Types of Muscle Tissue. most attached to bone. Learning Objectives. Describe the . anatomy . and . physiology . of skeletal muscle. Role of muscle fiber types as it relates to different types of athletic performances. Histochemical . techniques for identification of muscle fiber types. 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 . 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 does not always shorten a muscle:. The Muscular System. Muscles are responsible for all types of body movement. Three basic muscle types are found in the body. Skeletal muscle. Cardiac muscle. Smooth muscle. Characteristics of Muscles. It’s best to view this in . Slide Show . mode, especially for the quizzes.. This module will take approximately 75 minutes to complete.. The quiz for this module is long, and includes significant previous material from this and other blocks..
