Put these in order in terms of the pathway a nerve travels while throwing a ball: motor neuron, brain, muscles, sensory neuron.
Agree
What I think is Sensory neuron, brain, motor neuron, then the muscles.
To put these in order in terms of the pathway a nerve travels while throwing a ball, we need to understand the steps involved in the nervous system's role in this action.
1. Brain: The process of throwing a ball begins with a signal sent from the brain. The brain initiates the movement and coordinates the various muscles and joints involved.
2. Motor neuron: Once the brain sends the signal, it is transmitted to the motor neuron. Motor neurons are located in the central nervous system (CNS), which includes the brain and the spinal cord.
3. Muscles: The motor neuron carries the signal from the brain to the muscles. In the context of throwing a ball, the motor neuron stimulates the muscle fibers required for the throwing action.
4. Sensory neuron: After the ball is thrown, sensory information is generated by the movement. This information is then transmitted back to the brain via sensory neurons. They carry signals from the muscles and other body parts back to the brain, providing feedback about the action performed.
Therefore, the correct order in terms of the pathway a nerve travels while throwing a ball is:
Brain - Motor neuron - Muscles - Sensory neuron
