The snail-shaped structure within the ear that initiates the nerve impulse from the ear to the brain is the _______.
anvil
outer ear
ear canal
cochlea
Give the name AND the letter of the structure that carries impulses away from the neuron's cell body.
A; Synapse
B; Cell body
C; Dendrite
D; Axon
Give the name AND letter of the structure that contain the nucleus
A; Synapse
B; Cell Body
C; Dendrite
D; Axon
How does a nerve impulse cross structure A? (this is short answer on your test)
the neuron carrying the impulse releases chemicals that bridge the synapse
the axon carrying the impulse releases chemical that bridge the dendrite
the dendrite carrying the impulse releases chemicals that bridge the cell body
nerve impulses do not travel across the synapse
