Gross or Macroscopic Anatomy
The study of large structures visible to the naked eye: Regional, Systemic & Surface.
Regional
Studying structures according to region (abd pelvis chect ect.)
Systemic anatomy
Studying system by stetem, (cardiovascular,respiratory reproductive ect.)
Surface
Study of internal structures as they relate to overlying skin.
Microscopic anatomy
Deals with structures too small to be seen by the naked eye: Cytology and Histology.
Cytology
The cells in the body
Histology
The study of tissues
Develoopmental biology
Traces structural changes that occure throughout the life span. (embryology ia a subdivision)
Levels of organization
Chemical cellular tissue organ organ system organism
Necessary Life functions
Maintianing boundaries Movement Responsiveness Digestion Metabolism Excretion Reproduction Growth

Nutrients Oxygen Water Normal body temp Normal atmosphereic pressure
Homeostasis
Maintaining stable internal conditions inspite of changing external conditions.
Variable
The factor being regulated
3 Homeostaic controls
Receptor
Control Center
Effector
Receptor
Sensor that monitors the enviroment and responds to changes.
Control Center
Determins the set point, level or range that the variable is maintained.
Effector
Provides the means for the control centers responce to the stimuli
