Question 1

Cranial nerve X

Answer 1

vagus nerve, carries motor, sensory and parasympathetic fibers

passes through foramen jugulare

Question 2

ggl. proximale

Answer 2

located within the foramen jugulare

detaches

r. meningeus
r. auricularis - communicates with facial nerve within canalis facialis, supplies an area on the inner surface of the pinna

Question 3

ggl. distale

Answer 3

located at the detachment of the cranial laryngeal nerve

caudal to A.carotis interna and Ggl. cervicale craniale

Question 4

brnahces after the distal ganglion

Answer 4

1. r. pharyngei
2. n. laryngeus cranialis
3. n. depressor

joins with tr. sympatheticus to from tr.vagosympathetic

Question 5

R. pharyngeus

Answer 5

joins the glossopharyngeal nerve to form plexus pharyngeum

innervates: sensory to epiglottis, trachea and esophagus, constrictors of the pharynx

Question 6

r. laryngea cranialis

Answer 6

close to the distal ganglion, marks the end of the cranial vagus

divides into:

• r. externus - cricothyroid
• R. internus - sensory to larynx

Question 7

N. depressor

Answer 7

runs with the tr. vagosympathetic to the cardiac plexus, slows the heart rate

Question 8

Tr. vagosympatheticus

Answer 8

common course of the vagus and sympathetic trunk to the thoracic inlet

lies in vagina carotis together with the internal jugular (in dog) and carotis communi

Question 9

Thoracic portion of vagus nerve

Answer 9

sympathetic trunk leaves to form the ggl. cervicale medius

branches

• r. cardiaci
• n. laryngeus reccurens
• Tr. vagalis dorsalis
• Tr. vagalis dorsalis

Question 10

Abdomnial vagus nerve

Answer 10

Tr. vagalis dorsalis

• innervates
  
  • parasymp branches to celiac, mesenterica cranial and caudal ggl

Tr. vagalis ventralis

• stomach
• liver
• duodenum
