Description

1. As Roger is walking with the woman, he is so focused on what she is saying, he runs right into the glass door of the emergency room, hitting his nose directly. A wave of pain shoots through his body, and he yells in response. Explain how this process occurs using the following terms in context: a. Sensory neuron b. Peripheral nervous system c. Central nervous system d. Interneuron e. Motor neuron f. Action potential g. Neurotransmitter h. Synapse

Point 1: Sensory neuron: Students should explain that sensory neurons in the nose fire in response to bumping the nose. Point 2: Peripheral nervous system: Students should explain that messages from the rest of the body (including the sensory neuronal impulses that fired when the nose was bumped) travel through the peripheral nervous system on their way to the brain. Point 3: Central nervous system: Students should explain that sensory impulses from the rest of the body (including the message from the bumped nose) travel up the spinal cord to the brain. Point 4: Interneuron: Students should explain that messages travel within the body to the spinal cord and brain via interneurons. Point 5: Motor neuron: Students should explain that the brain sends messages to muscles through motor neurons (including the message to jump up and down and scream in pain). Point 6: Action potential: Students should explain that electrical charges travel within neurons during neural transmission. Point 7: Neurotransmitter: Students should explain that neurotransmitters are released in response to an action potential and these neurotransmitters travel to other neurons during neural transmission. Point 8: Synapse: Students should explain that neural transmission involves neurotransmitters flowing into the synapse, the gap between neurons, and these neurotransmitters may fire the next neural cell....
