Sympathetics Part 4

Question 1

What ganglion do the laryngeopharyngeal branches arise from to help form the pharyngeal plexus? What else helps form the pharyngeal plexus?

Answer 1

superior cervical ganglion;

fibers from the glossopharyngeal nerve, vagus nerve, and laryngeal plexus

Question 2

T/F:Both the pharyngeal and laryngeal plexuses supply blood vessels and glands.

Answer 2

True

Question 3

T/F: cardiac branches come from each of the cervical ganglia.

Answer 3

True

Question 4

Cardiac branches from each cervical ganglion accompany branches of what nerve through the cardiac plexus to the sinoatrial node?

Answer 4

vagus

Question 5

T/F: sympathetic stimulation will increase heart rate and constrict the coronary arteries.

Answer 5

False; dilates the coronary arteries

Question 6

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?

Answer 6

arrector pili, sweat glands, and blood vessels

Question 7

Which thoracic ganglia send postganglionic fibers to the thoracic aorta?

Answer 7

Ganglia 1-5

Question 8

Cardiac branches which pass through the cardiac plexus to extend directly to the heart are from which thoracic ganglia?

Answer 8

T2-T4 ganglia

Question 9

T/F: cardiac branches from the T2-T4 ganglia increase heart rate, dilate coronary arteries, and contain afferents as well.

Answer 9

True

Question 10

Pulmonary branches which assist in bronchial dilation and play a role in asthmatics arise from what ganglia? What plexus do these branches travel through?

Answer 10

T2-T4;

pulmonary plexus

Question 11

What all is supplied by the pulmonary branches emitted from the T2-T4 ganglia?

Answer 11

pleura, smooth muscle, and blood vessels of the lungs and bronchial glands

Question 12

Which ganglia contribute fibers to the greater splanchnic nerve?

Answer 12

T5-T9 or T10

Question 13

What plexuses are associated with the Greater splanchnic nerve on its way to the abdominal viscera?

Answer 13

gastric, hepatic, superior mesenteric and celiac plexuses

Question 14

T/F:Fibers from the greater splanchnic nerve supply the esophagus, thoracic aorta, and the diaphragm.

Answer 14

False; suppy the esophagus and thoracic aorta above the diaphragm

Question 15

Which ganglia contribute fibers to the lesser splanchnic nerve?

Answer 15

T9 or T10-T11

Question 16

The lesser splanchnic nerve supplies some of the same abdominal structures that the greater splanchnic nerve supplies, with the addition of what structures?

Answer 16

suprarenal glands

Question 17

Which splanchnic nerve contains fibers from the lowest thoracic ganglia and reaches the kidney through the renal plexus?

Answer 17

least splanchnic nerve

Question 18

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?

Answer 18

of each lumbar nerve (anterior and posterior primary rami)

Question 19

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?

Answer 19

As far as the median sacral artery and common iliac arteries

Question 20

Lumbar splanchnic nerves supply pelvic viscera via which plexuses?

Answer 20

superior and inferior hypogastric and inferior mesenteric plexuses

Question 21

T/F: lumbar splanchnic nerves travel from the sympathetic trunks directly to visceral structures.

Answer 21

True

Question 22

T/F: a gray ramus communicans is associated with each sacral and coccygeal nerve.

Answer 22

True

Question 23

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.

Answer 23

True

Question 24

Vascular branches from the pelvic sympathetic trunk accompany which blood vessel?

Answer 24

median sacral artery

Question 25

T/F: Pelvic Splanchnic nerves supply the pelvic viscera.

Answer 25

False; these are called sacral splanchnic nerves

Question 26

What nerves supply the pelvic viscera via the inferior mesenteric plexus?

Answer 26

Sacral Splanchnic nerves

Question 27

What nerves are branches from the pelvic sympathetic trunks that travel directly to visceral structures?

Answer 27

Sacral Splanchnic nerves

Question 28

What splanchnic nerves are branches from the sympathetic trunk which have fibers supplying the ureters and rectum?

Answer 28

Sacral Splanchnic nerves

Question 29

T/F: Fibers from the sacral splanchnic nerves which supply the ureters and rectum pass directly to these structures.

Answer 29

True
