BIOL4260 Study Guide - Midterm Guide: Hip Fracture, Hip Bone, Periodontal Fiber
Document Summary
Gross anatomy: regional- all structures in one part of the body, systemic- gross anatomy of the body studied by system, surface- study of internal structures as they relate to the overlying skin. Microscopic anatomy: cytology- study of the cell, histology- study of the tissue. Developmental anatomy: traces structural changes throughout life, embryology- study of developmental changes of the body before birth. Principle of complementarity: function always reflects structure, what a structure can do depends on its specific form. Homeostasis: the ability to maintain a stable internal environment in an ever-changing external world, the internal environment of the body is in a dynamic state of equilibrium, chemical, thermal, and neural factors interact to maintain homeostatsis. Negative feedback mechanism: the output shuts off the original stimulus, example: regulation of room temperature. Positive feedback mechanisms: output enhances or exaggerates the original stimulus, example: regulation of blood clotting.
