neural communication: the neural chain module 7: neural and hormonal systems
TRANSCRIPT
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?
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
Interneurons
• Nerve cells in the brain and spinal cord responsible for processing information related to sensory input and motor output
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
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.
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 –
