PHYS20008 Human Physiology 1:
Week 1-8 Lecture Notes on
Membrane Potential & Homeostasis
University of Melbourne
Physiology
Roslyn modules helpful
equilibrium potential of cell membrane: -70
Na: +60
K: -90
Human Physiology (PHYS20008)
is the study of how the body works and how it functions
Physiology 1
, week 1: homeostasis
homeostasis: the maintenance of a relatively constant internal environment
essential for the survival of each cell, and hence our bodies
we need:
a sensor to detect changes
controller or integrator - compare to a set point
response
Physiology 2
, e=exit
nerves = very fast
hormones are slow, hence not being released in situations
broad reaching things = hormones
