What are the correct order of steps on how a reflex occurs?

A bone moves.

A relay neuron sends a signal to a motor neuron.

A muscle receives a signal to contract.

A receptor detects a signal.

A sensory neuron sends a signal to the spinal cord.

Respuesta :

I believe this would be the correct order:

1) A receptor detects a signal.

2) A sensory neuron sends a signal to the spinal cord.

3) A relay neuron sends a signal to a motor neuron.

4) A muscle receives a signal to contract.

5) A bone moves.


A signal will be picked up by a sensory neuron and sent to the spinal cord (Central Nervous System). The signal will then be sent to a motor neuron in the Peripheral Nervous System to find a muscle. That muscle is signaled to contract which then will cause a bone to move.
