Question

when the baseball is traveling toward your face, your eyes detect the ball. this is your sensory. the message travels along a neuron, starting at the dendrite which receives the signal. the message moves through the, down the, and the helps the message travel faster and stay protected. the message then reaches the, which sends it to the next neuron or to your muscles. your brain and spinal cord process whats happening — this is called. finally, the signal goes out through nerves to your muscles — this is the, causing your arm to move and block the ball! think and reflect: how would damage to the myelin sheath affect the speed of nerve messages and your bodys reaction time?

Explanation:

• Sensory: Eyes detecting the ball is sensory input.
• Neuron, dendrite, cell body, axon, myelin sheath: Neurons have dendrites (receive signals), cell body (process), axon (transmit), and myelin sheath (insulate).
• Axon terminal: Sends message to next neuron/muscles.
• Integration: Brain/spinal cord processing.
• Motor response: Signal to muscles (motor).
• Myelin sheath damage: Slows nerve messages (less insulation), delays reaction.

Answer:

1. sensory
2. neuron, dendrite, cell body, axon, myelin sheath
3. axon terminal
4. integration
5. motor response
6. Damage to the myelin sheath would slow the speed of nerve messages (as myelin helps speed transmission) and increase the body's reaction time.
