introduction: to recognize the myelinated nerve fibers of the external capsule in human brain. materials and methods: 10 adult and normal brains (20 hemispheres) from both sexes were studied using 15 mm serial sections in all three cardinal planes after fixation and processing. these sections were stained by klüver - barrera and heidenhain - woelcke methods. results: some fibers from different ...

Using immunohistochemical methods, calcitonin gene-related peptide localizes to peripheral nerve fibers of the human and rhesus monkey eye. Immunoreactive nerve fibers are found in the cornea, about limbal blood vessels and in the trabecular meshwork. Many immunoreactive iris nerve fibers are present, mostly within the stroma. A particularly dense network occurs just anterior to the iris sphinc...

The innervation area of nociceptive C-fibers in the saphenous nerve of adult rats was detected by the Evans blue technique, in which antidromic excitation of the nociceptive C-fibers causes a visible extravasation of dye in the skin it supplied. One month after cutting the sciatic nerve, the nociceptive C-fibers of the intact saphenous nerve had sprouted to the sciatic area. When capsaicin was ...

Objective: The presence of nerve fibers in human endometrium remains unsettled but recent immunocytochemical studies have shown that there was increased innervation in the endometrium from women with endometriosis and some nerve fibers in the normally cycling human endometrium. In the current study, we used uterine tissue cryosections from normal cycling women, which previously provided better ...

background: hirschsprung disease is a complex genetic disorder of the enteric nervous system (ens), often called congenital aganglionic megacolon and characterized by the absence of enteric neurons along a variable length of the intestine. the definitive diagnosis of hirschsprung disease relies on histologic and/or histochemical staining of sections from suction rectal biopsies. calretinin immu...

In order to elucidate the mechanism of dentin sensitivity, the ultrastructure, distribution and organization of nerve fibers in the pulpodentinal border zone in the teeth of young human subjects were investigated by means of silver impregnation and electron microscopy. The nerve fibers in this zone were classified into four types by the location of their terminals and pattern of their ramificat...

Cell membrane has a critical and vital role in functioning and existence of nerve cells that form central nervous system (CNS) in mammals. Disruption of nerve membrane that normally occurs following an accident injuring spinal cord is known to be the major cause of paralysis. In most occasions, spinal cord injuries are not leading to complete cut in spinal cord fibers but are known to cause cru...

To determine the proportion of nerve fibers in the hypogastric nerve (HGN) and pelvic splanchnic nerve (PSN), small tissue strips of the HGN and PSN from 12 donated elderly cadavers were examined histologically. Immunohistochemistry for neuronal nitric oxide synthase (NOS), vasoactive intestinal peptide (VIP), and tyrosine hydroxylase (TH) was performed. More than 70% of fibers per bundle in th...
