摘要: Publisher Summary This chapter highlights the cell biology of subcommissural organ (SCO) and discusses its structure–function relationships to provide a basis for further experimental work. SCO is complex nonneuronal secretory cells covering penetrating posterior commissure. protrudes toward third ventricle, occupies portion diencephalic roof caudal pineal organ, marks entrance Sylvian aqueduct. formed by two populations cells, which, in many species, are arranged into distinct layers: ependyma hypendyma. The bulk products SCO, apparently containing different glycoproteins, released ventricular cerebrospinal fluid (CSF). In secretion condensed thread-like structure, Reissner's fiber (RF) that terminates ampulla caudalis central canal. blood vessels represent highly specialized vascular structure within CNS. sequestered double-barrier system unknown functional significance, thereby indicating unique character this circumventricular organ.
