Standard 9e Preknowledge
9e) Students know the roles of sensory neurons, interneurons, and motor neurons in sensation, thought, and response.
CALIFORNIA FRAMEWORKS SUMMARY:
The pathways of impulses from dendrite to cell body to axon of sensory neurons, interneurons, and motor neurons link the chains of events that occur in a reflex action. Students should be able to diagram this pathway. Similar paths of neural connections lead to the brain, where the sensations become conscious and conscious actions are initiated in response to external stimuli. Students might also trace the path of the neural connections as the sensation becomes conscious and a response to the external stimulus is initiated. Students should also be able to identify gray and white matter in the central nervous system.
