Cardiac and skeletal is musclesCardiac muscles: a type ofinvoluntaryStriated muscle found in the walls of theheart specially in the myocardium. Myocardium
Cardiac musclesMain types of cells:- Myocardial cells: Make up the artrium (the chamber in which blood enters the heart) and ventrical (where blood is pumped out of the heart) of the heart. These cells are necessary to the beating of the heart.
Cardiac musclesMain types of cells: Heart Cell- Electrical cells: -They carry the impulsesthat are responsible for the beatingof the heart. - Responsible for severalfunctions, like generate and sendout electrical impulses and receiveand respond to electrical impulsesfrom the brain.
Cardiac musclesStructure of cardiactissue - Cardiac muscle fibers arestriated, branched, and have asingle central nucleus. Thesecells are attached at their ends tothe fibres by thick plasmamembranes.
Cardiac muscles- The types of tissue:- Endocardium- Myocardium- Epicardium
Cardiac muscles• Endocardium The endocardium is the smooth layer of tissue that lines the walls of the heart. It has a shiny surface that allows blood to flow freely. Endocardium
Cardiac muscles• Myocardium The myocardium is the thick, muscular, middle layer of the heart. This layer is responsible for contracting the heart and sending blood to the body tissues. Myocardium
Cardiac muscles• Epicardium The epicardium or outer layer is a thin layer that serves to support in place and protect the heart.
Cardiac musclesOrgan:We can find cardiac muscles tissues in the heart.
Cardiac muscle- The functions: Pumping of blood through the heart: Alternate contraction and relaxation of cardiac muscle pumps
Cardiac muscles• Infectious Diseases of the Heart - Some infectious diseases cause inflammation of one of the cardiac tissue layers, resulting in permanent heart damage. A virus or type of bacteria typically causes these conditions.
Skeletal muscle tissueSkeletal muscle tissue:It’s a type of striated muscle that allows to dovoluntary physical movements of all types.
Skeletal muscleMain types of cells:Skeletal tissue is mainly made up of myocites.The cells that make up skeletal muscle tissue are Tissuelong and fibrous. Myocyte
Skeletalmuscle tissueStructure of skeletal tissue:
Skeletal muscleWe can find tissueskeletal muscletissue in themuscularsystem.
Skeletal muscle tissueFunctions of skeletal tissue:- Skeletal tissue work in pairs to coordinate themovements of the limbs, trunk, etc.- They are directly involved in breathing.
Skeletal muscle tissueDiseases of theskeletal muscle:Fibromyalgia is adisorder that causesmuscle pain and fatigue.People with fibromyalgiahave "tenderpoints" in the body. Tender points
Cardiac and skeletal muscle tissue• Questions:1. What is the main difference between cardiac and skeletal tissues?- Cardiac tissues are involuntary and skeletal tissue is voluntary.1. What is the main function of the cardiac muscle tissue?- Pumping blood through the heart.
