1. Neural Communication: The Neural Chain
Module 7: Neural and Hormonal Systems

2. Receptor Cells
Specialized cells in the sensory systems of the body that can turn other kinds of energy into action potentials that the nervous system can process
EX. Receptor cells in the eye turn light into a neural impulse the brain understands.
Examples from other senses?

3. Sensory Nerves
Nerves that carry information to the central nervous system
The receptor cell is the beginning of the chain
Connect the sense organs to the brain and spinal cord

4. Interneurons
Nerve cells in the brain and spinal cord responsible for processing information related to sensory input and motor output

5. Motor Nerves
Nerves that carry information from the central nervous system
Carries messages from the brain and spinal cord to other parts of your body

11. Personal example
Think of an example when you were in physical discomfort, but you “toughed it out” because you didn’t want people to make fun of you or think less of you.
Share it with a partner.

12. Reflex vs. thought process
Your example
Touch a hot burner on a stove – what do you do?
A baseball is coming quickly right at you – what do you do?
Blow in your face?
