Glomus cell

[2][3][4] The signalling within the chemoreceptors is thought to be mediated by the release of neurotransmitters by the glomus cells, including dopamine, noradrenaline, acetylcholine, substance P, vasoactive intestinal peptide and enkephalins.

The glomus type I cells of the carotid body are innervated by the sensory neurons found in the inferior ganglion of the glossopharyngeal nerve.

Alternatively, the glomus type I cells of the aortic body are innervated by sensory neurons found in the inferior ganglion of the vagus nerve.

Centrally the axons of neurons which innervate glomus type I cells synapse in the caudal portion of the solitary nucleus in the medulla.

[12] The autotransplantation of glomus cells of the carotid body into the striatum – a nucleus in the forebrain, has been investigated as a cell-based therapy for people with Parkinson's disease.

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.
Development of the nervous system. The glomus type I cells of the carotid body are derived from the neural crest and can be seen in green.
