Lecture 1 - definitions homeostasis Flashcards
Macroscopic/gross anatomy
examine large, visible structures
Microscopic anatomy
examine cells and molecules
Anatomy
study of STRUCTURES of the body
Physiology
study of FUNCTION of body structures
Surface anatomy
Macroscopic
exterior features
Regional anatomy
Macroscopic
body areas
systemic anatomy
macroscopic
groups of organs working together
developmental anatomy (embryology)
Macroscopic
from embryo to maturity
clinical anatomy
macroscopic
medical, radiological and surgical specialties
histology
microscopic
tissues and their structures
cytology
microscopic
cells and their structures
Cell physiology
processes within and between cells
special physiology
function of specific organs
systemic of physiology
function of organ systems
Pathological physiology
effects of diseases
what are the specialties of physiologies?
cell, special, systemic, pathological
what is the organization of living organisms
atom, molecule/chemical, organelle, cell, tissue, organ, organ systems, organisms
Homeostasis
process of maintaining a stable internal environment within the body
has a normal RANGE not fixed level
what does disease mean (homeostasis)
failure to function within a normal range
What are the mechanisms of homeostatic regulation
Intrinsic regulation
extrinsic regulation
intrinsic regulation
automatic response in a cell tissue or organ
extrinsic regulation
response controlled by endocrine and nervous systems
parts of regulatory mechanism and job
receptor - receives the stimulus
center - process the signal, sends instructions
effector - carries out instructions
negative feedback and examples
the response of the effector reverses the stimulus, stimulus reduces response
body temp
blood glucose level
positive feedback and examples
the response of the effector reinforces the stimulus, stimulus increases response
blood clotting
oxytocin in labour
system integration
systems work together to maintain homeostasis
