a homeostatic regulatory system consists of 3 parts which are

1.) a receptor - a sensor that is sensitive to a particular stimulus or environmental change 2.) a control center - receives and processes the information supplied by the receptor and sends out commands 3.) an effector - a cell or organ that responds to the commands of the control center and whose activities opposes or enhances the stimulus

5 types of gross anatomy

1.) surface anatomy 2.) regional anatomy 3.) systemic anatomy 4.) developmental anatomy 5.) clinical anatomy
