Learning Outline
Nervous System Overview
The outline for the nervous system is very large, so I’ve split it into two parts:
Part 1 and Part 2.
Pretty easy to follow so far, eh?
Do the overview on this page first, then navigate to Nervous System 1
and then to Nervous System 2.
We will only very briefly touch on the senses.
Introduction to the nervous system

The reflex arc
Afferent pathway (afferent = toward)
- Receptor — sensory mechanisim to receive stimulus
Integrator
- Receives sensory information and determines what (if any) response to make
Efferent pathway (efferent = away from)
- Effector — muscle, gland, or other cell that receives motor output
