division of anatomy studying development developmental
phisiology-study of how body parts work physiology
anatomical study that reduces organs to tissues and cells reduction
anatomical study that studies how things work by putting them back together synthesis
gross anatomy study of all structures in one part of the body regional
gross anatomy study according to the system they belong to systematic
gross anatomy study of internal structures as they relate to the overlying skin surface
microscopic anatomy studying cells cytology
microscopic study of tissues histology
principle that states that function always reflects structure; what a structure can do depends on its specific form principle of complementarity
_____-cells-tissues-_____-organ system-organism chemicals, organs
7 basic life function maintain boundaries, responsiveness, growth, reproduction, differentiation, movement, metabolism
hypterplasia increase in cell number
hypertrophy increase in cell size
occurs after reproduction, how fertilized eggs become all organs/systems differentiation
means of movement locomotion, propulsion, contractility
