| A | B |
|---|
| anatomy | "to cut apart" -- the study of the structures of an organism |
| physiology | "the nature of" -- the study of the function of an organism |
| Why do we study A&P together? | b/c structure (anatomy) determines function (physiology) |
| cytology | the study of cells |
| histology | the study of tissue |
| Microscopic anatomy | study of structures that can only be observed with magnification |
| Gross anatomy | study of structures that can be seen w/ the naked eye |
| Systemic anatomy | study of the organ systems of the body |
| What are the level of Organization of matter of an organism? (small 2 large) | atom, molecule, organelle, cells, tissue, organ, organ systems, organism |
| atom | smallest unit of matter |
| molecule | atoms chemically & covalently combined |
| organelle | parts of "little cells" carry out cellular functions |
| cells | smallest structural & functional units of life |
| tissue | group of specialized cells, working together to perform specific functions |
| organ | 2 or more tissues together that perform specific functions |
| organ systems | organs working together to produce coordinated effects |
| organism | whole living thing |
| What are the 4 primary tissue types | Epithelial, Connective, Muscle, Neural |
| Structural Characteristics of Epithelial Tissue | Cellularity, Polarity, Attachment, Avascular, Regeneration |
| Functions of Epithelial Tissue | Provides physical protection, Control permeability, Provide sensations, Produe specialized secretions |
| Classification of Epithelial Tissue | simp. squam, strat. squam, simp. cub, strat. cub, trans, simp. col, psedo. col, strat. col |
| Exocrine Gladular Epithelial Tissue | cells secrete substance through a duct onto an epithelial surface |
| Endocrine Glandual Epithelial Tissue | cells secrete substance directly into extracellular fluid for transport via the blood stream |
| Epithelial Tissue | includes cells that form a barrier and glands *always exposed to external envir.* |
| Connective Tissue | "connecting" tissue found throughout body |
| Structual Components of Conn. Tissue | specialized cells, extracellular protein fibers, extracellular ground substance |
| Fluid Connective Tissue | specialized cells in fluid matrix -- blood, lymph |
| Supporting Connective Tissue | specialized cells in a solid matrix -- cartilage, bone |
| Muscle Tissue | cells specialized for contraction |
| Types of Muscle Tissue | skeletal, cardiac, smooth |
| Neural Tissue | cells specialized for conduction of electrical impulses |
