Sample Answer
- Sensory neurons detect basket position and distance through vision.
- This information travels to the brain for processing and decision-making.
- Players judge distance and height to plan shot trajectory, which shows how sensory input initiates movement.
- Motor neurons transmit signals from brain to muscles.
- These signals cause coordinated contractions for jumping and shooting.
- Leg muscles power the jump while arms control ball release, demonstrating how motor neurons execute movement.
- The autonomic system increases heart rate and breathing.
- This provides extra oxygen and energy for the movement.
- Blood flow increases to working muscles during the shot, thus supporting voluntary actions involuntarily.
