list. There are three main types of muscles. Cardiac muscles‚ skeletal muscles and smooth muscles‚ these particular muscle types are the main muscles of the muscular system and work together with other systems of the body to perform homeostasis. Muscles work together to provide the body with posture and other positions‚ they also have the ability to contract causing movements like walking and more subtle movements like smiling and breathing. The cardiac muscle is an involuntary muscle of the heart;

HISTOLOGY PURPOSE: The purpose of this exercise is to be able to identify and correctly name the major tissue types in the body‚ as well as identifying the subcatergories of tissue types while observing them through the microscope and diagrams‚ and be able to explain the location and function of the tissue types in the body. There are not any real safety concerns for this lab other than making sure correct use and care of the microscope is used. EXERCISE 1: EPITHEILIAL TISSUE Epithelial Tissue Observations

Structure and Function There are three types of muscle tissue—smooth‚ skeletal‚ and cardiac. Each has its own distinctive function‚ and therefore‚ its own distinctive structure‚ but all muscles allow movement of some kind. Skeletal Muscle Skeletal muscle is called voluntary because you can control this type of muscle. You can

makes our joints move quickly‚ so there needs to be more synovial fluid in the joints to allow and assist this movement When we start to warm up: • The muscles need energy in the form of glycogen to make the sarcomeres contract. – So the heart (cardiac muscle) beats faster to provide the glycogen to the muscles via the blood. • The conversion of chemical energy (from the Glycogen) to movement (contraction of the

Action potential‚ impulse conduction (italics)‚ and cardiac cycle (bold) Pacemaker cells in the SA node‚ found in the wall of right atrium‚ begin as polarized‚ with Na+ on the outside of the cell (sarcolemma) and the cell at its resting potential (-80 mV in the atria‚ -90 mV in the ventricles). The atria are full or filling with blood. The SA (and technically the AV) nodal cells gradually drift towards their threshold after each repolarization and depolarize (the prepotential: spontaneous depolarization)

Responsiveness- is a property of all living cells- Muscle and nerve cells have developed this property to the highest degree. When stimulated by chemical signals‚ stretch‚ and other stimuli‚ muscle cells respond with electrical changes across the plasma membrane. b. Conductivity- Stimulation of a muscle cell produces

EXTERNAL PACEMAKERS: These are used when the heart block presents itself as an emergency and when it is expected to be present for a short time i.e during critical post operative periods and in patients during cardiac surgery‚ involving the valves or septum. * The pacemaker is placed outside the body. It may be in the form of wrist watch or in the pocket‚ from that one wire will go into the heart through the vein. * The electrodes are called endocardiac
