Identify the principal structures of a neuron and describe the functions of each.
What will be an ideal response?
Neurons contain a cell body or soma, which contains much of the machinery of the cell. The nucleus is within the cell body and contains the chromosomes of the cell. The dendrites of a neuron receive signals from presynaptic neurons. The axon of a neuron extends from the cell body and is responsible for carrying signals to the end of the neuron. At the end of the neuron are the axon terminals, which contain vesicles in which neurotransmitter is packaged. Signals are sent from the axon terminal to postsynaptic neurons via the synapse, which is the space between neurons.
