PPT-Structure and Function of Skeletal Muscle

Skeletal Muscle Human body contains over 400 skeletal muscles 4050 of total body weight Functions of skeletal muscle Force production for locomotion and breathing Force production for postural support. 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. ).. Special Terms. Plasma Membrane . 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. 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 36. CHAPTER 36.1. THE SKELETAL SYSTEM. HW: P. 925 #1-4. THE SKELETON. Functions: . Supports the body. Protects internal organs. Enables movement. Stores mineral reserves. Site for blood cell formation. Produce movement. Maintain posture. Stabilize joints. Generate heat. The Muscular System. Muscles are responsible for all types of body movement. Three basic muscle types are found in the body. Skeletal muscle. made up of over 600 different muscles. consists of two different . types of tissue: . connective tissue. muscle tissue. What is the Muscular System?. What are the Functions of the Muscular System?. To create movement by working with bones, ligaments, and tendons.. 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. In its Second Edition, this text addresses basic and applied physiological properties of skeletal muscle in the context of the physiological effects from clinical treatment. Many concepts are expanded and recent studies on human muscle have been added. This new edition also includes more clinically relevant cases and stories. A two-page full color insert of muscle sections is provided to ensure integral understanding of the concepts presented in the text. Anyone interested in human movement analysis and the understanding of generation and control from the musculoskeletal and neuromuscular systems in implementing movement will find this a valuable resource.
