The carotid body is situated on the posterior aspect of the bifurcation of the common carotid artery. [3] The carotid body is made up of two types of cells, called glomus cells: glomus type I cells are peripheral chemoreceptors, and glomus type II cells are sustentacular supportive cells. Glomus type I cells are derived from the neural crest. [4]

Behind the angle of bifurcation of the common carotid artery is a reddish-brown oval body known as the carotid body. It is similar in structure to the coccygeal body which is situated on the median sacral artery. The relations of the cervical region of the common carotid artery may be discussed in two points:
The carotid body is not labelled but is located within the wall of the internal carotid artery near the bifurcation of the common carotid artery. Glomus type I cells are the chemoreceptor cells found in the carotid body. Glomus cells are the cell type mainly located in the carotid bodies and aortic bodies. Glomus type I cells are peripheral ...
Carotid bodies are considered the primary peripheral chemoreceptor and have been shown to contribute more to a hypoxic response. However, in the chronic absence of the carotid body, the aortic body is able to perform a similar respiratory regulatory role, suggesting that it possesses efficacious mechanisms of signal transduction as well.

the abdominal region encompassing the stomach area; the umbilical region is located around the navel; the coxal region encompassing the lateral (side) of hips; the pubic region encompassing the area above the genitals. The pelvis and legs contain, from superior to inferior, the inguinal or groin region between the thigh and the abdomen,
The external carotid artery is covered by the skin, superficial fascia, platysma muscle, deep fascia, and anterior margin of the sternocleidomastoid; it is crossed by the hypoglossal nerve, by the lingual, ranine, common facial, and superior thyroid veins; and by the digastricus and stylohyoideus muscles; higher up it passes deeply into the ...
