Physiology - How each sense operates:
Vision
-pigments react to light source
-initiate control over 2nd messenger system
Physiology - How each sense operates:
Hearing
Hair cells are stimulated when sound waves or head movement cause disruption of fluid and then hair cells that are connected to gates send signals to associated nerves
Physiology - How each sense operates:
Equilibrium
Hair cells are stimulated when sound waves or head movement cause disruption of fluid and then hair cells that are connected to gates send signals to associated nerves
Physiology - How each sense operates:
Olfaction
Chemical dissolved stimulates receptors, channels open, receptor, action potential is 2nd messenger system
Physiology - How each sense operates:
Gustation
chemical binds to receptor and elicits a graded potential that causes neurotransmitter release will cause an action potential to send to the parietal lobe
