motor neurons
sensory neurons
interneurons

Neurons and Neural Transmission
7
Neural Transmission
An action potential is a brief electrical charge that travels down the axon. As the electrical charge travels down the axon to the terminals, it helps to release the chemical messengers (neurotransmitters).

Look for in the video:
-action potential firing
-positive ions entering and exiting axon (selectively permeable)
-neurotransmitters in the synapse

A neuron is like a toilet...
Resting potential
All-or-none (reach threshold)
Action potential
Refractory
no reuptake
13
Multiple Choice
A function of dendrites is to
receive incoming signals from other neurons
release neurotransmitters into the spatial junctions between neurons
coordinate the activation of the parasympathetic and sympathetic nervous systems
control pain through the release of opiate-like chemicals into the brain
transmit signals to other neurons
14
Multiple Choice
The longest part of a neuron is likely to be the
dendrite
axon
cell body
synapse
neurotransmitter
15
Multiple Choice
The speed at which a neural impulse travels is increased when the axon is encased by a(n)
soma
myelin sheath
dendrite
synaptic cleft
reuptake
16
Multiple Choice
A brief electrical charge that travels down the axon of a neuron is called the
synapse
axon
action potential
myelin sheath
refractory period
17
Multiple Choice
The depolarization of a neural membrane can create a(n)
action potential
myelin sheath
motor neuron
reuptake
interneuron
18
19
Multiple Choice
A gap between neurons that transmits neural messages to other neurons is called the
dendrite
synapse
axon
cell body
vesicle
20
Multiple Choice
Neurotransmitters are released from vesicles located on the knoblike terminals at the end of the
dendrites
cell body
terminal branches
myelin sheath
