Mentioned in this article as A part of the axial skeleton is a third subdivision, the visceral, comprising the decreased jaw, some components with the higher jaw, along with the branchial arches, such as the hyoid bone.
biogenic amine – course of neurotransmitters that are enzymatically derived from amino acids but now not incorporate a carboxyl team.
Defense of the heart, lungs, and also other organs and structures during the upper body results in a problem relatively various from that on the central nervous program.

cardiac reflexes – series of autonomic reflexes that permit the cardiovascular centres to manage heart purpose primarily based on sensory facts from many different visceral sensors.
axon – single process of the neuron that carries an electrical sign (motion opportunity) clear of the mobile body toward a target mobile.
