A&P Part 1

definition of anatomy

• the study of diseases

• the study of structure

• the study of life

• the study of function

definiton of physiology

• study of function

• study of structure

• study of disease

• study of life

homeostasis

• physiology adjustments to preserve homeostasis

• disease leading to illness or death

• maintance of stable internal environment

• substance held together with postive and negative feedback

hierarchical order

• chemical, cellular, tissue, organ, organ system, organism

• tissue, organ, organ system, organism, cellular, chemical

• cellular, chemical, tissue, organ, organ system, organism

• chemical, cellular, tissue, organism, organ system, organ

receptor (sensor)

• responds to command

• processes information and sends command

• recieves stimulation

• adjust temperature

control center (integration center)

• keeps internal envirmoent

• recieves stimulation

• responds to command

• process information and sends command

effector

• recieves stimulation

• responds to command

• sends out command

effector prevents stimulus, primary mechanism of homeostatic, dynamic process, minimizes change

• positive feedback

• negative feedback

accelerates change, exaggerates original change, produce extreme responses

• positive feedback

• negative feedback

negative feedback accelerates process of change

• true

• false, postive
