Sympathetic nerve fibers in human cervical and thoracic vagus nerves.
BACKGROUND Vagus nerve stimulation (VNS) therapy has been used for chronic heart failure and is believed to improve imbalance of autonomic control by increasing parasympathetic activity. Although it is known that there is neural communication between the VN and the cervical sympathetic trunk, there are few data regarding the quantity and/or distribution of the sympathetic components within the ...
متن کاملSchwannomatosis of Cervical Vagus Nerve
Cervical vagal schwannoma is a rare entity among lesions presenting as a neck mass. They are usually slow-growing benign lesions closely associated with the vagus nerve. They are usually solitary and asymptomatic. Multiple schwannomas occurring in patients without neurofibromatosis (NF) are rare and have recently been referred to as schwannomatosis. Here, we present a case of a neck mass that h...
متن کاملArterial baroreceptor fibers from the aortic region of the dog in the cervical vagus nerve.
The neural pathways followed by sensory fibers from arterial baroreceptors in the aortic region of the dog were investigated with neurophysiological recording. Systemic arterial baroreceptor fibers separate from the depressor nerve were found in the left cervical vagus in each of five dogs investigated; at most two fibers were isolated from each dog due to the difficulty of the dissection. Thes...
متن کاملPositional Relationship between Natural Killer Cells and Distribution of Sympathetic Nerves in Decidualized Mouse Uterus
Background: Uterine natural killer (uNK) cells are the most abundant leukocytes in pre-implantation endometrium and early pregnancy deciduas in humans and rodents. They are associated with structural changes in maternal spiral arteries but regulation of their re-cruitment and activation is incompletely understood. The major subpopulation of uNK cells in humans expresses CD56, the neural cell ad...
متن کاملAbnormalities in the vagus nerve in canine acrylamide neuropathy.
Dogs exposed to acrylamide develop a sensorimotor peripheral neuropathy and megaoesophagus. The presence of neuropathy was confirmed electrophysiologically and histologically. Hindlimb motor conduction velocity was reduced and there was a loss of large diameter myelinated fibres in the dorsal common digital nerve and the tibial nerve. The conduction velocity of vagal motor fibres innervating th...
