Describe the major structures of a neuron that are encountered as a message travels through the nervous system. Make sure you cover the neural structures in the correct order
What will be an ideal response?
The neural structures that would be encountered that are covered by the chapter include the following (in order):
(a) dendrites – receiving ends or "branches" of the neuron
(b) cell body – the center of the cell that contains the basic biological machinery that keeps the neuron alive
(c) axon – a tubelike structure that transmits a message to other neurons and is covered and protected by Myelin
(d) terminal buttons – small knobs at the end of a neuron that release neurotransmitters
(e) neurotransmitters – chemical substances that allow neurons to communicate with each other.
