Question

in transmitting sensory information to the brain, an electrical signal travels * 2 points from the ______________ of a single neuron.
cell body to the axon to the dendrites
dendrites to the axon to the cell body
dendrites to the cell body to the axon
axon to the dendrites to the cell body

a brief electrical charge that travels down the axon of a neuron is called * 2 points the
myelin sheath
synapse
action potential
agonist

Explanation:

1. Neurons receive signals at dendrites, process in the cell body and then transmit from the axon. So for the first question, electrical signal travels from dendrites to the cell body to the axon.
2. An action potential is a brief electrical charge that travels down the axon of a neuron. Myelin sheath insulates axon, synapse is the junction between neurons and agonist affects neurotransmission.

Answer:

1. dendrites to the cell body to the axon
2. action potential
