Nervous
1. Make and fill in this chart
Draw a neuron and label the following parts: cell body, dendrite, axon, myelin sheath, axon terminal
Part of Neuron
Dendrite
Axon
Myelin Sheath
Axon Terminal
Synapse
Function
Branch off cell body, receive neurotransmitters and place where action
potential begins
extension of cell body that nerve impulse travels along
lipid layer around axon, acts as an insulator
end of the axon, where nerve impulse/action potential ends an
where neurotransmitters are released from
Space between axon terminal of one neuron and dendrite of another
where neurotransmitters are released
2. Describe the process of how a nerve impulse is transmitted along a neuron. Be sure to use the terms
synapse, axon terminal, dendrite, neurotransmitters, action potential.
An action potential begins at a dendrite where it has received neurotransmitters from the neuron
before it. The action potential travels across the cell body, down the axon, to the axon terminals. It
stops there and causes the release of neurotransmitters from the axon terminals into the synapse.
Then the neurotransmitters will bond to the dendrite of the next cell to start another action potential.

something
e. Temperature: _thermoreceptor_______
f. Smell: ___chemoreceptor____
g. Taste: ___chemoreceptor_______
5. Name the two main parts of the nervous system.
Central nervous system (brain and spinal cord), Peripheral nervous system (carries messages to and
from CNS, all the other nerves)
6. The somatic nervous system controls __skeletal muscle (voluntary)_____ and the autonomic nervous
system controls __glands, internal organs, smooth muscle (involuntary)___.
Endocrine
Write “E” if the statement refers to the endocrine system and write “N” if the statement
refers to the nervous system.
