Neuron Physiology Vocab

Question 1

Action Potential

Answer 1

A sequence of electrical activities that responds to and then delivers a stimulus

Question 2

Equilibrium State

Answer 2

Condition in which the concentration and electrical diffusion are balanced

Question 3

Excitatory Post-Synaptic Potential

Answer 3

Initial depolarization that occurs when excitatory neurotransmitter reaches a neuron

Question 4

Inhibitory Post-Synaptic Potential (IPSP)

Answer 4

Prevents action potential by inducing hyperpolarization

Question 5

Absolute Refractory Period

Answer 5

No action potential can be triggered during this time

Question 6

Relative Refractory Period

Answer 6

An action potential can be triggered, but the amount of excitatory stimulus is greater than normal

Question 7

Synapse

Answer 7

Points where one neuron connects with another

Question 8

Pre-synaptic Cell

Answer 8

First cell that is sending message to the next cell

Question 9

Post-Synaptic Cell

Answer 9

Cell that is receiving message from the pre-synaptic cell

Question 10

Autoreceptors

Answer 10

Neurotransmitter receptors on the pre-synaptic neuron that inhibits release and/or synthesis of more neurotransmitter
