our body mass is composed of muscle. Types of Muscular Tissue There are three types of muscle tissue: 1. Skeletal Voluntary movement‚ attached to bones. 2. Smooth Involuntary movement‚ found in digestive tract‚ circulatory system‚ etc. 3. Cardiac Involuntary movement‚ found only in heart. Muscle Contraction Skeletal Muscle Muscle fibers Myofibrils Filaments Two types of filaments: - Thick: contain protein called myosin - Thin: contain protein called actin The alternation

I will be describing and explaining the acute immediate effects of exercises on the skeletal and muscular system. There are four main responses to exercise Increased blood supply to the muscles‚ Increased muscle pliability‚ Increased range of movement at joints and Muscle fibre micro tears. Increased Blood supply to our muscles When we are exercising our heart rate increases. During exercise more blood is pumping out of the heart and around the body. When our heart beats faster more blood

Week 1 Chapter 1 1. What is the basic difference between anatomy and physiology? (p. 2) ANSWER: Anatomy (a-NAT-ō-mē; ana- = up; -tomy = process of cutting) is the science of structure and the relationships among structures. Physiology (fiz′-ē-OL-ō-jē; physio- = nature‚ -logy = study of) is the science of body functions‚ that is‚ how the body parts work. 2. Define each of the following terms: atom‚ molecule‚ cell‚ tissue‚ organ‚ system‚ and organism. (p. 6) ANSWER: AtomUnit of matter that makes

Duchenne Muscular Dystrophy Duchenne muscular dystrophy is a fatal genetic disorder that causes progressive muscle weakness throughout your body. This disorder is caused my mutations in the dystrophin gene. The dystrophin gene is responsible for the production of a muscle protein. So the muscles suffer a loss of protein and contractile fibers. Then the muscles replaced with fat and connective tissue. DMD mostly affects young males exclusively due to an x-linked recessive inheritance pattern

ADInstruments With acknowledgement to: Dr. Stuart I. Cromarty‚ Department of Natural Sciences‚ Assumption College‚ Worcester‚ MA‚ USA. [pic] Background Smooth muscle is one of three muscle fiber types found in animals. Unlike skeletal and cardiac muscle cells‚ smooth muscle cells are not striated‚ and have single nuclei. Smooth muscles are typically under control of the autonomic nervous system‚ and do not contract voluntarily. Smooth muscle contracts slowly‚ and does not exhibit the characteristic

There are many differences between probation and parole. There are also many different definitions of probation‚ one that I believe is a good one is the action of suspending the sentence of one convicted of a minor offense and granting him provisional freedom on the promise of good behavior. Parole is the release of a prisoner before is term has expired on condition of continued good behavior. The similarities between the to is the person convicted of the crime has to show good behavior in order
