What ion is responsible for the exocytosis of the neurotransmitter from the terminal bouton of the neuron?
Calcium (Ca++)
What refers to a separation of opposite charges across the membrane?
Voltage or Membrane potential.
Inside of a neuron is ____ by charge during the restins potential
Negative.
What is the resting membrane potential of a typical nerve cell?
-70mV
Communication between neurons occurs by the release of chemical messengers, AKA?
neurotransmitters
Newly opened channels for _____
ions close at the end of repolarization?
Potassium (K+)
Taste receptors are also known as?
Chemoreceptors
The ________ of the brain is the CNS center for afferent fibers from the taste receptor cells.
Temporal lobe
All sensory perception must pass thru _____?
The temporal lobe
What do the semicircular canals detect?
angular acceleration (dynamic equilibrium)
The utricle and saccule respond to
(static equilibrium)
What does sound waves amplitude deteremine? Sound wave frequency?
Loudness
Pitch
The cones contain color sensitive photopigments, which are?
Red, blue, green, and yellow
What protein are photopigments made up of?
Opsin
During the alarm phase of the gerneal adaptation syndrome, draw the Hypothalamic-Pituitary-Adrenal diagram and explain the list effects on the body
see notes
Can the same neurotransmitter cause opposite effects in different cells?
look this up
In setting the membrane potential, what components are important?
The levels of sodium and potassium being maintained by the ATPase Pump
Flying with dim light, which photoreceptors are affected? explain?
Rods because they are affected by dim light.
Flying with dim light, draw how photoreceptors transduce light and why is the pilots nutritional status be important?
see notes.
*retinal is made from vitamen
and not enough in your diet may cause night blindess.
Flying with dim light, if everything nutritionally is normal, what might cause this problem?
If any of the steps are faulty in transduction, it might contribute to her condition.
Flying with dim light impaired vision... should the pilot be able to fly?
No, because good vision is required to fly and if she can't see well in dim light, she might not be able to make good judgments and crash the plane.
Draw and label an action potential. Draw the changes in sodium and potassium.
see notes.
