Glomus caroticum (carotid body) (I) in human
9.7 POJA-L2909+3370+2910+2912+3369
Title: Glomus caroticum (carotid body) (I) in human
Description:
Carotid body, stain hematoxylin-eosin. The glomus caroticum belongs to the non-chromaffin paraganglia system, and is located at the bifurcation site of the arteria carotis communis and the aorta ascendens. The glomus functions as a peripheral chemoreceptor by
assessing both the oxygen and carbon dioxide level in the blood. In addition the receptors are sensitive for pH and temperature.
(A, 1; B, 1) Arteria carotis communis. (A, 2) Glomus caroticum.
(B, C): Glomus (paraganglion) (B - D, 2). (B, 3) Lymph node. (B - D, 4) Common ganglion. (C, 5) Nerve bundle.
(D): Detail glomus showing the clusters of neuroendocrine cells surrounded by an ample vascularization network and stromal
supportive cells. (4) Common ganglion with numerous ganglion cells.
(E): Details of glomus or paraganglion showing the cluster of light-stained neuroendocrine cells with round nuclei surrounded by
an ample capillarization network, and smaller denser-stained supportive cells.
They comprise two cell types: the main cells (glomus type I cells) which are round-like being able to release biogenic amines various neurotransmitters and a supporting cell type (glomus type II cells or sustentacular cells) a glia-like cell type, being slightly elongated.
The main cells are derive from the Anlage of the sympathetic system. (i.e. neural crest).
