Back 1

Calcium (Ca++)

Front 2

What refers to a separation of opposite charges across the membrane?

Back 2

Voltage or Membrane potential.

Front 3

Inside of a neuron is ____ by charge during the restins potential

Back 3

Negative.

Front 4

What is the resting membrane potential of a typical nerve cell?

Back 4

-70mV

Front 5

Communication between neurons occurs by the release of chemical messengers, AKA?

Back 5

neurotransmitters

Front 6

Newly opened channels for _____
ions close at the end of repolarization?

Back 6

Potassium (K+)

Front 7

Taste receptors are also known as?

Back 7

Chemoreceptors

Front 8

The ________ of the brain is the CNS center for afferent fibers from the taste receptor cells.

Back 8

Temporal lobe

Front 9

All sensory perception must pass thru _____?

Back 9

The temporal lobe

Front 10

What do the semicircular canals detect?

Back 10

angular acceleration (dynamic equilibrium)

Front 11

The utricle and saccule respond to

Back 11

(static equilibrium)

Front 12

What does sound waves amplitude deteremine? Sound wave frequency?

Back 12

Loudness
Pitch

Front 13

The cones contain color sensitive photopigments, which are?

Back 13

Red, blue, green, and yellow

Front 14

What protein are photopigments made up of?

Back 14

Opsin

Front 15

During the alarm phase of the gerneal adaptation syndrome, draw the Hypothalamic-Pituitary-Adrenal diagram and explain the list effects on the body

Back 15

see notes

Front 16

Can the same neurotransmitter cause opposite effects in different cells?

Back 16

look this up

Front 17

In setting the membrane potential, what components are important?

Back 17

The levels of sodium and potassium being maintained by the ATPase Pump

Front 18

Flying with dim light, which photoreceptors are affected? explain?

Back 18

Rods because they are affected by dim light.

Front 19

Flying with dim light, draw how photoreceptors transduce light and why is the pilots nutritional status be important?

Back 19

see notes.
*retinal is made from vitamen
and not enough in your diet may cause night blindess.

Front 20

Flying with dim light, if everything nutritionally is normal, what might cause this problem?

Back 20

If any of the steps are faulty in transduction, it might contribute to her condition.

Front 21

Flying with dim light impaired vision... should the pilot be able to fly?

Back 21

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.

Front 22

Draw and label an action potential. Draw the changes in sodium and potassium.

Back 22

see notes.
