PPT-Skeletal Muscle Lecture packet 8

Reading Chapter 5 Copyright 2008 Pearson Education Outline Overview of the skeletal system Function of bones Bone structure Bone cells Cartilage Tendons and ligaments. What is Muscle Tissue?. Composed of cells that are highly specialized to shorten in length by contractility.. Made up of cells that are called . myocytes. .. Elongated in one direction (muscle . fibres. Muscular . System Functions:. Muscle Tissue Can Contract (shorten) and Relax (lengthen). This causes mobility and provides support.. Allow for movement of:. skeleton – muscles are connected to bones. 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. Chapter 8. Muscle Spasm and Spasticity. Spasticity is a central nervous system dysfunction . Spasticity is technically not a disease process but a result of motor interruption (lesion), typically in the upper motor complex of the central nervous system. 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. Objectives. Histologically identify and functionally characterize each of the 3 types of muscle tissues.. Describe the organization of the sarcomere as seen in light and electron microscopy.. Identify the .

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.. Degeneration Figure Legend:Figure 1Skeletal muscleDegeneration in a male Harlan SpragueDawley rat from a subchronic study. A central myofiber is swollen and hypereosinophilic(arrows), and a fragmented There are many striking similarities in the reactions of mammalian skeletal muscle to denervation and the normal aging process. In both cases, the tissue environment is far more complex than has commo Prof. Dr. . Anna L. Kiss . Department. of . Anatomy. , . Histology. and . Embryology. Semmelweis University. Budapest . 2021.
