Neurophysiology - L6

Question 1

Afferent Receptor

Answer 1

Responsible for taking potential to the CNS, and brings toward second order neuron

Question 2

Adequate Stimulus

Answer 2

Means the correct form of energy to create a response. The brain knows what to feel based on what neuron

Question 3

Mechanoreceptors

Answer 3

Touch vibration, and hearing use this, use stretch on carbohydrate chains in extracellular space to change conductance.

Question 4

Proprioreceptors

Answer 4

tells us where we are in space

Question 5

Exteroreceptors

Answer 5

External receptors for things like light sound and touch

Question 6

enteroreceptors

Answer 6

like receptors internally like in the gut or other internal organs. In the viscera. Taste and smell and baroreceptors

Question 7

Frequency Code

Answer 7

How to code for strength of a signal is through increasing frequency of signal.

Question 8

Range Fractionation

Answer 8

Different fivers carry different peices of the range.
so you do not need to have so many potentials in a row
as one fiber reaches maximum frequency another just reaches threshold

Question 9

Adaptation

Answer 9

Delayed reduction in sensativity can be fast or slow

Question 10

Phasic Receptors

Answer 10

Rapidly adapting, only care about new stimulus

Question 11

Tonic Receptors

Answer 11

Slowly adapting

Question 12

Chemoreceptors

Answer 12

go through g protein getting to a membrane depolarization

Question 13

Photoreceptors

Answer 13

photons go to rhodopsin to a g-protein activating PDE

reducing sodium channels shutting down and hyperpolarization

Question 14

Receptor Potential

Answer 14

An example of this is the taste bud. it is a type of graded potential produced by the activation of a receptor potential
