Afferent vagal impulses in anaphylactic bronchial asthma.
The role played by both lung stretch and lung deflation components of the pulmonary vagus has been studied, in order to throw further light on the changes in lung mechanics which underlie the lung deflation receptor activity and hence the activation of respiration during an asthma attack. The discharge pattern of the lung stretch receptors varies from unit to unit, but also in one and the same ...
متن کاملNeuroanatomy of visceral nociception: vagal and splanchnic afferent.
Afferent fibres convey sensory information from the upper gastrointestinal tract to the central nervous system but the nature of this information is different for vagal and spinal pathways. Vagal afferents convey predominantly physiological information while spinal afferents are able to encode noxious events. Because of the different response profiles following activation of these pathways, it ...
متن کاملWarm-sensitive afferent splanchnic C-fiber units in vitro.
Receptive fields of 41 slowly conducting sensory fibers were located using a thermal (warm) search stimulus in an in vitro splanchnic nerve-mesentery preparation. Warm-sensitive receptive fields were punctate and were densest in the region surrounding the prevertebral ganglia, an area with prominent deposits of brown adipose tissue, where the abdominal aorta branches into the major trunks suppl...
متن کاملCerebral Phosphoprotein Promoted by Electrical Impulses
It has been shown (Heald, 1956b) in cerebral slices that duringtherapidbreakdown ofphosphocreatine, brought about by brief passage of electrical pulses (see Heald, 1954), there is an increased exchange of phosphate between the phosphates soluble in trichloroacetic acid and those in the insoluble residue. Thus in cerebral slices which had been allowed to metabolize radioactive inorganic phosphat...

われわれヒトを含めて哺乳類の身体は,皮 膚 に よって外部環境から隔てられた 個体 を形成 してお り,皮 膚にある外受容器 と眼,耳,鼻 にある遠隔 受容器によって外部環境の変化 を刺激 として受容 し,そ れに対する反応 として行動 を起す。この行 動は骨格筋の収縮によって実現 されるもので,外 部環境に対する個体 としての反応は,身 体内部の 筋,腱,迷 路にある固有受容器に対する刺激 とな り,こ れ らの受容器から身体の運動 と位置に関す る情報が中枢に送 られる(Sherrington1947)91)。 筋紡錘および腱紡錘は筋 と腱に存在する代表的な 固有受容器であり,こ れ らからの情報によって, 運動の円滑な遂行が反射性に制御 されていること が,多 数の研究者によって 明らかに されて いる (Matthews196463),Granit197027),Matthe...
