Question Answer
Homeostasis relatively constant internal environment
Anatomy study of the structures of the body and physical relation among body parts
Physiology study of how living organism perform vital functions
Medical Terminology use of root words prefixes and suffixes to construct terms related to the body
Gross Anatomy macroscopic examination of large structures and features usually visible with the unaided eye
Surface Anatomy Study of general form and superficial markings
Regional Anatomy focus on anatomical organization and specific areas and the body
Systemic Anatomy study of the structure of organ systems
Organ systems groups of organs that function together in a coordinated manner
Developmental Anatomy describes the changes in for that occur between conception and physical maturity
Embryology stay of the development between the fist 2 months
clinical anatomy a number of subspecialties important in clinical practice
microscopic anatomy Structures that can't be seen with out magnification
cytology study of internal structure of individual cells
cells simplest unit of life
histology examination of tissues
tissues groups of specialized cells and cell products that work together
organs tissues combined to form
human physiology study of functions of human body
cell physiology study of cell functions
organ physiology study of the physiology of specific organs
systemic physiology all aspect of the functioning of specific organ systems
pathological physiology study of the effects of diseases on organ functions or system functions
chemical or molecular level atoms
cellular level molecules can interact to form various types of organelles
tissue level tissue group of cells working together to perform one or more specific functions
the organ level organs consist of 2 or more tissues working in combination to perform several functions
organ system level group of organs interacting to perform a particular function forms and organ system
organism highest level of organization
homestasis existence if a stable internal environment
homeostatic regulation adjustment of physiological systems to preserve homeostasis
Auto regulation a cell, tissue, organ,organ system, adjusts its activities automatically in response to some environmental change
extrinsic regulation results from the activities if the nervous system or endocrine system
receptor sensor that is sensitive to a particular stimulus or environmental change
control center receives and processes information supplied by the receptor and sends out commands
effector cell or organ that responds to commands of control center and activity opposes or enhances stimulus
negative point a way to counter act an effect
hypothalamus region of brain with control center
positive feedback produces a response that exaggerates or enhances the original change
superficial anatomy locating stuctures on or near bodies surface
