Anatomy & Physiology |
Anatomy- study of structure of body parts and their relation to one another Physiology- study of the function of body parts; how they work to carry out life- sustaining activities |
Definition |
|
|
1- Gross or macroscopic anatomy |
The study of LARGE visible structures |
Topic of anatomy Subdivisions of anatomy |
|
|
2- Microscopic anatomy And two other studies |
Deals with structures to SMALL to be seen by naked eye Cytology- study of cells Histology- study of tissue |
Topic of anatomy Subdivisions of anatomy |
|
|
3- Developmental anatomy And one other study |
Studies anatomical and physiological developments throughout life Embryology- study of development before birth |

|
|
Homeostasis |
The maintenance of relatively stable internal conditions despite condition despite continuous changes in environment - maintained by contributions of all organs |
|
|
|
What systems are constantly being monitored to maintain homeostasis? |
Nervous and endocrine system |
|
|
|
Homeostasis- Receptor |
-monitors environment (temperature) - responds to all stimuli (stimuli- things that cause changes in controlled environments) |
Homeostasis control of variables |
|
|
Homeostasis- Control Center |
- determines set point at which variable is maintained - receives input from receptor - determines appropriate response |
|
|
|
Homeostasis- Effector |
- receives output from control center - provides the means to respond - response either reduces stimulus (- feedback) or enhances stimulus (+ feedback) |
|
|
|
Negative feedback |
- most-used feedback mechanism in body - response reduces or shuts off original stimulus *ex- regulation of blood glucose by insulin |
|
|
|
Positive feedback |
- response enhances or exaggerates the original stimulus - may exhibit a cascade or amplifying effect as feedback causes variable to continue in same direction as initial change - usually controls infrequent events that do not require continuous adjustment *ex- platelets blocking a tear in blood vessel |
