Sample Answer
Similarities:
- Both sensory and motor neurons are essential components of the peripheral nervous system.
- Both transmit electrical signals rapidly through myelinated axons during the bowling action.
- Both work together in a continuous feedback loop throughout the bowling sequence.
- Both are activated simultaneously to coordinate the complex bowling movement.
Differences:
- Sensory neurons detect stimuli (grip feel, body position, visual cues) while motor neurons cause muscle contractions.
- Sensory neurons transmit signals from receptors to the CNS; motor neurons transmit from CNS to muscles.
- Sensory neuron cell bodies are located in dorsal root ganglia; motor neuron cell bodies are within the CNS.
- Sensory neurons enable proprioception for body awareness; motor neurons enable precise sequential muscle contractions.
- Sensory neurons provide feedback about execution; motor neurons execute the planned bowling action.
