The area postrema in mammals other than rodents and lagomorphs is a bilateral mound of gelatinous-appearing tissue that protrudes into the caudal fourth ventricle on either side of the obex. In rodents and lagomorphs it is a single midline structure at the apex of the calamus scriptorius. The vasculature is derived mainly from the posterior inferior cerebellar arteries and consists mainly of sinusoidal capillaries. It appears to constitute a portal system, at least in the rat. Many of the capillaries are fenestrated, and many large perivascular spaces with both vascular and parenchymal basal laminae are present. The cell population is composed of flattened ependymal cells exhibiting microvilli, and of small neurons, normal astrocytes, glialoid cells, and a very few oligodendroglia. Mast cells are occasionally present. The glialoid cells appear to be the predominant cell type and exhibit great numbers of vascular podia. Axodendritic synapses are numerous and axosomatic synapses are occasionally seen in the parenchyma. Synaptic vesicles are mainly of the clear-cored type but large dense-cored vesicles are commonly observed in some axon terminals.
