Innervation especially sensory innervation of duodenum in white rat.

چکیده
perfection of staining methods, the results were tainted with defects. In 1932, the epochal discovery of the terminal formation of the vegetative nerve fibres, that is the terminalreticulum, was made by Stohr1) and Reiser,2) after a painstaking labor. Subsequent observations by many investigators on the subject led to a remarkable illustration of the problem. On the other hand, the sensory nerves in these parts have hitherto been entirely passed over, perhaps owing to the inveterate notion that no such nerves are found in these regions. However, in the latest days, it has been ascertained that sensory nerve fibres do exist in these parts by Seto3) and Sato4) in our laboratory. In succession to the above mentioned discovery of sensory nerves, I have been able to ascertain the existence of sensory nerves in the duo denum as well as the stomach of the white rat. On the latter I have reported my findings previously.5) I will make a statement on the in nervation of duodenum of the white rat, with special emphasis of sensory nerves, hereunder. The materials of study were fixed, for a long period, in 10% neutral formol, and cut into 40ƒÊ frozen sections, which were stained by Seto's silver impregnantion. Then, the preparations stained very beautifully were subjected to minute microscovic observation.

Quantification of neuroepithelial bodies and their innervation in fawn-hooded and Wistar rat lungs.
The Fawn-Hooded rat (FHR), a model for primary pulmonary hypertension, shows an unexplained hypersensitivity to airway hypoxia. Because pulmonary neuroepithelial bodies (NEBs) appear to express a functional oxygen-sensing mechanism and an extensive sensory innervation, possible changes in this system should be taken into consideration. In the present study a comparative analysis of NEBs and the...
متن کاملOntogeny of the serotonergic projection to rat neocortex: transient expression of a dense innervation to primary sensory areas.
The development of serotonergic innervation to rat cerebral cortex was characterized by immunohistochemical localization of serotonin combined with autoradiographic imaging of serotonin-uptake sites. In neonatal rat, a transient, dense, serotonergic innervation appears in all primary sensory areas of cortex. In somatosensory cortex, dense patches of serotonergic innervation are aligned with spe...
متن کاملThematic review series: adipocyte biology. Sympathetic and sensory innervation of white adipose tissue.
During our study of the reversal of seasonal obesity in Siberian hamsters, we found an interaction between receptors for the pineal hormone melatonin and the sympathetic nervous system (SNS) outflow from brain to white adipose tissue (WAT). This ultimately led us and others to conclude that the SNS innervation of WAT is the primary initiator of lipid mobilization in these as well as other anima...

The thyroid hormones have profound effects on the development of neuromuscular system. These hormones exert their influence on both muscle fibers and related motoneurons during development. Masseter is one of the most important muscles for mastication in mammals. Thyroid hormone deficiency 3 weeks after birth, the period in which an alteration from sucking to biting occurs, could influence the ...
متن کاملSensory or sympathetic white adipose tissue denervation differentially affects depot growth and cellularity.
Functional and histological evidence for the sympathetic nervous system (SNS) innervation of white adipose tissue (WAT) exists for several species; however, its sensory innervation has only been shown in laboratory rats, and its function is unclear. We tested the effects of sensory and SNS innervation of Siberian hamster epididymal and inguinal WAT (EWAT and IWAT) by assessing calcitonin gene-r...
