The stratified inner layer of the embryonic fetal brain, the ventricular zone (VZ), contains glial fibrillary acidic protein (GFAP)-positive cell bodies of radial glia. The adult cerebral ventricle is lined by a single layer of cuboidal, ciliated common ependymal cells which are, immunohistologically, GFAP negative. In late gestation, the ventricular lining(More)
The fine structure of a neuroendocrine complex within the lamina propria of the human appendix is described. This complex contains four types of neurosecretory cells, occasional neurons, Schwann cells, and numerous nerve processes, including axons with varicose swellings. Few of the axons form true synapses, but many make some junctional contact with the(More)
The lamina propria of the human appendix possesses a recently defined ganglionated neural plexus with neurosecretory-type component cells. In order to elucidate the functional role of this plexus, immunohistochemical light and electron microscopic studies were performed on 21 appendixes. By light microscopy, 18 specimens showed within the lamina propria(More)
