Name: __________________________________________ Section: ________________________ Date: __________________________________________
This activity explains the way that neurons communicate with each other.
Match the part of the neuron identified with its description:
o B Axon
___ A. Contains the nucleus, which controls the
function of the entire cell o D Axon terminals
___ B. Carry signals to other nerve cells A Cell body (soma)
o ___ C. Receive signals from other nerve cells o ___
C Dendrites D. Contain small sacs called synaptic vesicles
that play an important role in transmitting signals from
one cell to the next A Tip
• Dendrites ______________________
• Axons _________________________
A Closer Look
• What does it mean to say that an axon’s membrane is “selectively permeable?” It means that some molecules can pass easily through the membrane, while others can only
pass through special channels controlled by gates.
• Given what you know about synaptic transmission, how do you think a message jumps across the
synaptic gap and is passed to the next neuron? Messages travel by neurotransmitters signaling different receptors until it reaches
their destination. ...
