Create a reflex arc to show the sequence of events that happens in the network of our nervous system when we accidently step on a thorn?

The pain signal generated by the spine is first captured by the receptors on the damaged or "punctured" surface.

After that, through the afferent path the signal is sent to the medulla, where a rapid response is given that does not ascend to the CNS, that is why it responds in milliseconds through the afferent path, in turn the afferent pathway generates the stimulation of the alpha motor neuron that triggers muscle contraction in order to carry out the "withdrawal" of the foot or hand or other part that was damaged by the spine.

Explanation:

The named parts are:

efferent neurons: neurons in charge of sending signals from the motor-reflex medulla to the muscle cells by means of the alpha motor neuron.

afferent neurons: neurons responsible for carrying the signal from the receptors to the medulla.

It must be understood that the path of the reflex act is a path that does not reach the central nervous system area, but rather are rapid medullar responses
