PPT-Muscles Part II MUSCLE CONTRACTIONS

Static Dynamic Isometric Isotonic Isokinetic Constant External Resistance Variable Resistance Plyometrics Muscle Contraction Static contractions The muscle tension or force exerted against an external load is equal to or weaker than the external force. Muscles. : . Types, Fibres & Movement patterns . Types of Skeletal Muscle:. Within our skeletal muscle we actually have . 2 types of muscle fibre . called . fast. and . slow twitch . fibres, related to the speed in which they contract.. Objective. : To learn the structure and function of the Muscular System. Bell Work. : . Put the terms in the correct order from most simple to most complex: . SKELETAL MUSCLE. STRIATED MUSCLE CELL. MUSCULAR SYSTEM. Part 2. Action Potential. Acetycholine. is released and . __________ . rushes into cell causing an electrical charge. Na. Muscles contract more forcefully after they have contracted a few times. . Objective. : . To learn the structure and function of the Muscular System. Bell Work. : . Muscles need lots of energy to complete their job. Which organelle do you think is most abundant inside muscle cells?. To know the meaning of origin and insertion of a. variety of muscles. To understand the different muscular movements. To be able to develop a mind map on joints. and movements.. STARTER. IN PAIRS IDENIFTY THE TYPE OF . Figure 6.8. Contraction of a Skeletal Muscle. Muscle fiber contraction is “all or none”. Within a skeletal muscle, not all fibers may be stimulated during the same interval. Different combinations of muscle fiber contractions may give differing responses. 1. Interactions of Skeletal Muscles. Skeletal muscles work together or in opposition. Muscles only pull (never push). As muscles shorten, the insertion generally moves toward the origin. Whatever a muscle (or group of muscles) does, another muscle (or group) “undoes. Learning Objectives:. Describe the functions of the muscular system. Identify structures of the muscular system and the function of each. Describe methods of assessment of the muscular system. Describe disorders of the muscular system. What is a Bone ? ?. - Main components:.
