genetic conditions characterized by progressive muscle weakness and wasting (atrophy). The Duchenne and Becker types of muscular dystrophy are two related conditions that primarily affect skeletal muscles‚ which are used for movement‚ and heart (cardiac) muscle. These forms of muscular dystrophy occur almost exclusively in males. Duchenne and Becker muscular dystrophies have similar signs and symptoms and are caused by different mutations in the same gene. The two conditions differ in their severity

muscle‚ cardiac muscle‚ and skeletal muscle. Smooth muscle is located in the digestive tract and in the walls of blood vessels. It moves food through the digestive system. Cardiac muscle is found only in the heart. This muscle pumps blood throughout your body. Skeletal muscle is attached to your bones to help you move. Muscle action can be voluntary or involuntary. The muscles that you control are voluntary and the muscles that you do not control are involuntary. Smooth muscle and cardiac muscle

Skeletal System Skeletal system is the biological system providing support in living organisms. Skin‚ muscle and bones allow movement. Skin - pliable covering. Muscles do actual moving. Bones give anchor to move against. The skeleton functions not only as the support for the body but also in haematopoiesis‚ the manufacture of blood cells that takes place in bone marrow. This is why people who have cancer of the bone marrow almost always die. It is also necessary for protection of vital organs

Purpose The purpose of this experiment was to become familiar with the electrocardiograph to help us determine the electrical activity of the heart. As well as‚ to observe how exercise and different body positions(conditions) can affect the activity of the heart. Introduction Trained professionals can look at the EKG tracing and determine if the heart is normal or if the heart is abnormal. “An ECG records the electrical activity of the heart. The heart produces tiny electrical impulses which spread

Tissues Essay There are four major categories of tissues in the human body. Each of them separate into even smaller groups with specific structures and functions. The four major types are epithelial tissue‚ connective tissue‚ muscle tissue and cardiac tissue. They are all necessities of the human body and contribute to many functions our bodies and cells carry out in order to survive. Tissues interact and group together to make up organs which then compose systems and the human body all together

10.1 OVERVIEW OF MUSCULAR TISSUE Types of muscular tissue There are 3 types of muscular tissue: skeletal‚ cardiac‚ & smooth. All 3 may share some things but they differ from one another in their microscopic anatomy‚ location‚ & how they are controlled by the nervous and endocrine systems Skeletal muscle tissue function of most is to move bones of the skeleton (are few that attach to other structures ex--the skin). Muscle tissue is striated b/c alternating light and dark protein bands (striations)

contain sarcomeres‚ which are made up of thick protein filaments known as actin and myosin. All of these components make up the two types of fibers‚ slow-twitch and fast-twitch. The muscles also contain 3 distinct tissues known as cardiac‚ skeletal‚ and smooth. Both cardiac and smooth muscle cells are under involuntary control and are located in the walls of organs; however‚ the skeletal fibers occur in muscles which are attached to the skeleton and are under voluntary control. Muscles are specialized

Why? This is because the cardiac muscle cells depolarize 4. How do the sympathetic and parasympathetic nervous systems work together to regulate heart rate? Sympathetic neurons increase the heart rate while the parasympathetic neurons decrease the heart rate and the heart stimultaneously receives both neurons signals 5.

Simultaneous contraction occurs in both‚ the right and the left; that is mean between tricuspid and bicuspid valves. 3. The atria contraction sends impulses
