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

No, it’s not the best way. The flowchart shows the process step by step, but the intricacies would only be clear to a person who knows the major parts of the nervous system and how they interact with each other.

Explanation: answer on Plato

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

answer; the above answer to the above statement is (true)
