Sympathetics Part 4 Flashcards
What ganglion do the laryngeopharyngeal branches arise from to help form the pharyngeal plexus? What else helps form the pharyngeal plexus?
superior cervical ganglion;
fibers from the glossopharyngeal nerve, vagus nerve, and laryngeal plexus
T/F:Both the pharyngeal and laryngeal plexuses supply blood vessels and glands.
True
T/F: cardiac branches come from each of the cervical ganglia.
True
Cardiac branches from each cervical ganglion accompany branches of what nerve through the cardiac plexus to the sinoatrial node?
vagus
T/F: sympathetic stimulation will increase heart rate and constrict the coronary arteries.
False; dilates the coronary arteries
Fibers from the gray rami communicans associated with each thoracic nerve supply structures in the field of distribution of their respective thoracic nerves. What structures are supplied?
arrector pili, sweat glands, and blood vessels
Which thoracic ganglia send postganglionic fibers to the thoracic aorta?
Ganglia 1-5
Cardiac branches which pass through the cardiac plexus to extend directly to the heart are from which thoracic ganglia?
T2-T4 ganglia
T/F: cardiac branches from the T2-T4 ganglia increase heart rate, dilate coronary arteries, and contain afferents as well.
True
Pulmonary branches which assist in bronchial dilation and play a role in asthmatics arise from what ganglia? What plexus do these branches travel through?
T2-T4;
pulmonary plexus
What all is supplied by the pulmonary branches emitted from the T2-T4 ganglia?
pleura, smooth muscle, and blood vessels of the lungs and bronchial glands
Which ganglia contribute fibers to the greater splanchnic nerve?
T5-T9 or T10
What plexuses are associated with the Greater splanchnic nerve on its way to the abdominal viscera?
gastric, hepatic, superior mesenteric and celiac plexuses
T/F:Fibers from the greater splanchnic nerve supply the esophagus, thoracic aorta, and the diaphragm.
False; suppy the esophagus and thoracic aorta above the diaphragm
Which ganglia contribute fibers to the lesser splanchnic nerve?
T9 or T10-T11
The lesser splanchnic nerve supplies some of the same abdominal structures that the greater splanchnic nerve supplies, with the addition of what structures?
suprarenal glands
Which splanchnic nerve contains fibers from the lowest thoracic ganglia and reaches the kidney through the renal plexus?
least splanchnic nerve
Fibers from the grey rami communicans of the lumbar sympathetic trunk supply the arrector pili, sweat glands and blood vessels in the field of distribution of what nerves?
of each lumbar nerve (anterior and posterior primary rami)
Vascular branches are given off of the lumbar sympathetic trunk that follow the lumbar arteries back to the abdominal aorta. How far do these branches follow?
As far as the median sacral artery and common iliac arteries
Lumbar splanchnic nerves supply pelvic viscera via which plexuses?
superior and inferior hypogastric and inferior mesenteric plexuses
T/F: lumbar splanchnic nerves travel from the sympathetic trunks directly to visceral structures.
True
T/F: a gray ramus communicans is associated with each sacral and coccygeal nerve.
True
T/F: fibers from gray rami communicans supply arrector pili, sweat glands, and blood vessels in the field of distribution of each nerve they are associated with.
True
Vascular branches from the pelvic sympathetic trunk accompany which blood vessel?
median sacral artery
T/F: Pelvic Splanchnic nerves supply the pelvic viscera.
False; these are called sacral splanchnic nerves
What nerves supply the pelvic viscera via the inferior mesenteric plexus?
Sacral Splanchnic nerves
What nerves are branches from the pelvic sympathetic trunks that travel directly to visceral structures?
Sacral Splanchnic nerves
What splanchnic nerves are branches from the sympathetic trunk which have fibers supplying the ureters and rectum?
Sacral Splanchnic nerves
T/F: Fibers from the sacral splanchnic nerves which supply the ureters and rectum pass directly to these structures.
True
