NERVOUS SYSTEM AND NEURON MODELING

PART 1: MODELING NEURONS


The axon terminal is at the end of the dendrites (forgot to label it).

Unipolar Neuron

 The axon terminal is at the end of the dendrites on this one too!

Bipolar Neuron

Yes, you guessed it, the axon terminal is at the end of the dendrites!

Multipolar Neuron

What is a good idea to help remember the directions of afferent and efferent neurons sent messages to or from the central nervous system?

The way I remember the direction afferent and efferent neurons travel is by reminding myself that Efferent neurons are the effectors.  They are the signals that tell the body what actions to take which causes an effect.  By remembering that efferent means effect, I then know that Afferent does the opposite and sends information to the CNS.
