  • Histamine,
  • Bradykinin,
  • Prostaglandin

This is further explained below.

<h3>What is Histamine?</h3>

Generally, Histamine, a substance that may be present in certain cells of the body, is the culprit behind many of the symptoms of allergies, such as sneezing and runny noses.

This may cause a wide range of uncomfortable symptoms.

A neuron will emit a signaling substance called a neurotransmitter in order to influence the behavior of some other cell across a synapse.

It's possible that the cell that receives the signal is another brain, but it might also be a gland cell or a muscle cell. Any key body component or target cell may be getting the signal.

In conclusion, The neurotransmitters that are released at the site of injury are

  • Histamine,
