1.1 PRINCIPLES OF HUMAN PHYSIOLOGY 6TH EDITION
1. What is physiology?: the study of the functions of organisms, comes in many
forms—plant physiology, cell physiology, microbial physiology, and animal physiology
2. What is an organ system?: is a collection of anatomical structures that work
together to carry out a specific function.
3. What are nuerons?: nerve cells
4. What are cells?: smallest living units
5. What are the 4 major classes present in the body?: 1) neurons, (2)
muscle cells, (3)
epithelial cells, and (4) connective tissue cells.
6. What are muscle fibers?: muscle cells
7. What is epethilia?: continuous, sheetlike layers of cells found in the skin and
linings of hollow organs;
specialized to regulate exchange; singular, epithelium
8. What is basement membrane?: thin underlying layer of noncellular
material
9. simple (cell description): one layer thick
10. Stratified (cell description): several cells thick
