Guyton-Hall. Chapter 6. Skeletal muscle. Physiology lecture notes Medical MBBS MD DO students

This video has outline notes of Chapter 6 of Textbook of Medical Physiology by Guyton-Hall, 14th Edition. Contraction of Skeletal Muscle. Outline notes have been placed into slides in the same order as described in the Textbook. Figures and Tables are also included from the Textbook. This is a self-study video and no commentary is included. Hold video in each segment, read it thoroughly and then resume video to move to next segment. You are strongly advised to read the notes from this video along with reading the Textbook of Physiology. Reading the Textbook of physiology is very important. *Muscle Types*: Skeletal muscle: attached to bones and under voluntary control. Cardiac muscle: found in the heart and under involuntary control. Smooth muscle: found in various organs and under involuntary control. *Sarcolemma*: The plasma membrane of a muscle cell. *Myofibrils*: Composed of actin and myosin filaments. *Titin*: A protein that keeps myosin and actin filaments in place. *Sarcoplasmic reticulum*: Regulates calcium storage. *Acetylcholine*: A neurotransmitter substance secreted by nerve endings. *Myosin head*: Functions as an ATPase enzyme. *Troponin-tropomyosin complex*: Inhibitory in nature and must be inhibited before contraction can take place.
