3. Types of Neurons
Dendrite

5. Types of Neurons There are 3 types of neurons.
Sensory Neurons  Neurons located near receptor organs (skin, eyes, ears).
Function: receive incoming stimuli from the environment.
Motor Neurons  Neurons located near effectors (muscles and glands)
Function: Carry impulses to effectors to initiate a response.
Interneurons  Neurons that relay messages between other neurons such as sensory and motor neurons. (found most often in Brain and Spinal chord).

6. Worksheet Label the worksheet titled “Neurons and parts”
Fill in the table for comparison of the 3 types of neurons

8. Action Potential
The mechanism by which neurons send impulses. They are comprised of electrical signals generated at the cell body and moving along the axon toward the end opposite the cell body (motor neurons)
Action potentials occur in two stages:
Depolarization
Repolarization
