Muscle physiology: Physiology is the study of the function of living systems, the mechanical, physical, and biochemistry of function and energy transfer. Muscle physiology is concerned with the types of muscle tissues (of which there are three). Here I discuss skeletal muscle specifically.ach muscle fiber in a motor unit is of the same type; hence, motor units are divided into fast and slow units. Generally speaking, slow motor units are innervated by small, slowly conducting motor neurons and fast units by large rapidly conducting motor neurons.
Top 10 Causes of Death. Heart disease and stroke were the leading causes of death in 2001, regardless of countries' incomes, the study shows. However, other leading causes of death differed depending on countries' incomes. Here is the list for high-income countries: 1  Heart disease. 2  Stroke. 3  Lung cancer. 4  Lower respiratory infections. 5  Chronic obstructive pulmonary disease (COPD). 6  Colon and rectum cancers. 7  Alzheimer's disease.
COPD is a major leading cause of death in Australia. In 2013, 6,462 people were recorded as having died from COPD (3,572 males and 2,890 females) making it the fifth leading cause of death after coronary heart disease, cerebrovascular disease, dementia and Alzheimer disease, and lung cancer.
