PPT-Properties of Cardiac muscle

Part 1 Dr Arun Goel Associate professor Department of Physiology Properties of cardiac muscle Properties of the cardiac muscle Excitability The ability to respond to a stimulus of adequate strength and duration ie threshold or more by generating a propagated action potential. 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. Dr. Ayisha Qureshi . Assistant Professor,. MBBS, MPhil. Location of the Heart:. The Pericardium & the Pericardial Sac: . The . heart is enclosed in the double-walled, membranous . pericardial sac . Muscle Tissue Characteristics. Contractile. Made of contractile proteins. Cells are called fibers. Skeletal Muscle. 40% of body weight. Under voluntary control; attached to skeleton. Striated, or banded, appear. Pamela BL. Introduction . The cardiac muscle forms the muscular wall of the heart that is it forms the myocardium.. Some of the cardiac muscle is also present in the walls of the aorta, pulmonary vein and superior vena cava.. 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 . 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 . Histology Lecture . Series. Larry . Johnson, Professor. Veterinary Integrative Biosciences.

PLASMA ENZYME LEVELS. As metabolically complex cells, hepatocytes contain high levels of a number . of . enzymes. With liver injury, these enzymes may leak into plasma and can . Contractile.

Cells have multiple nuclei. The tongue is the strongest muscle in the body (relative to size). There are about 640 skeletal muscles in the human body. It takes twice as long to lose new muscle if you stop working out than it did to gain it.. Here are some cardiac problem signs including chest discomfort, nausea, throat or jaw pain and more which you should never ignore. Prof. Dr. . Anna L. Kiss . Department. of . Anatomy. , .
