The following unusual variations were observed while making a routine dissection of a newborn white child. The left subclavian artery arises from the right subclavian on the right side of the neck. It then curves upward and to the left and passes dorsally, in succession, the right internal jugular vein, common carotid artery, vagus, cervical sympathetic and inferior laryngeal nerves, and the sc...

We investigated whether stroking stimuli near the external auditory meatus while listening to sounds enhances pleasant feelings. Previous studies have demonstrated that vibratory manipulate emotions evoked by watching videos or sounds; however, none effects of through which vagus nerves extend. Participants were exposed three types with and without their ears, selected one stimulus condition in...

Women diagnosed with complete spinal cord injury (SCI) at T10 or above report vaginal-cervical perceptual awareness. To test whether the Vagus nerves, which bypass the spinal cord, provide the afferent pathway for this response, we hypothesized that the Nucleus Tractus Solitarii (NTS) region of the medulla oblongata, to which the Vagus nerves project, is activated by vaginal-cervical self-stimu...

It has been shown in this paper that stimulation of the inhibitory nerves of the neurogenic heart of Limulus, which correspond to the vagus nerves of the vertebrate heart, results in a marked diminution of CO(2) production in the heart ganglion, while stimulation of the ganglion, leading to increased activity of the heart, leads also to increased CO(2) production by the ganglion. This shows tha...

PLATE 74. It has been shown by one of us (I) that the normal production of impulses in the region of the sino-auricular node is inhibited by stimulation of the right vagus nerve to a greater extent than by stimulation of the left. Earlier observations, which are fully discussed in that paper, had indeed indicated that such might prove to be the case ; but a clear demonstration of the prepondera...

Stimulation of mechanoreceptors in skeletal muscles such as contraction and stretch elicits reflexive autonomic nervous system changes which impact cardiovascular control. There are pressure-sensitive mechanoreceptors in skeletal muscles. Mechanical pressure stimulation of skeletal muscles can induce reflex changes in heart rate (HR) and blood pressure, although the neural mechanisms underlying...

IT MAY BE CONCLUDED FROM THE RESULTS OBTAINED IN THESE EXPERIMENTS : 1. That stimulation of the right vagus nerve in the dog usually causes arrest of all the chambers of the heart. 2. That stimulation of the left vagus nerve exerts a moderate negative chronotropic effect on the auricles. 3. That stimulation of the left vagus nerve has a profound effect on the conduction of impulses over the aur...

Objective: In this review we focused on understanding the cause-and-effect relationships of gastroduodenal pathology aiming to clarify the role of vagus nerve. Results: The spectrum of vagus nerve biological effects in gastroduodenal area is related to its numerous targets and a wide range of its receptors. A variety of vagus nerve effects are related to the broad expression of cholinergic rece...

Stimulation of discrete intracardiac sympathetic nerves to the SA (SAS stimulation) or AV nodal region (AVS stimulation) increased the heart rate or decreased AV conduction time and caused an AV junctional rhythm, respectively, in anesthetized dogs treated with atropine. Topical application of tetrodotoxin (TTX) at the SAS or AVS stimulation locus totally inhibited the response to each stimulat...
