What are the two major subsystems of the nervous system?
The neuron is composed of the following parts (NICHD, 2018):
- Nucleus
- Cell body
- Dendrite: responsible for receiving information via synapses for the cell to process and send through the axon, through the axon terminal, to the synapse to be passed on again
- Axon: the “corridor” through which sensory information is passed to the dendrite to be sent to another neuron. ...
