Respiratory + Endocrine Flashcards
Weird pair but whatever
Innervation of the larynx
Mucosa: cranial laryngeal n.
Muscles: caudal (recurrent) laryngeal n.
The gutteral pouch is a diverticulum of what structure?
Auditory tube
Which important structures run along the caudal margin of the medial compartment of the guttural pouch?
Medial compartment
CN 9-12 + sympathetic trunk extending cranial to the cranial cervical ganglion
Internal carotid a.
Which important structures run along the caudal/lateral margin of the lateral compartment of the guttural pouch?
External carotid a.
Facial n.
What is the surgical (anatomic) approach to the guttural pouch?
“Viborg’s triangle”
Caudal border of mandible
Tendon of sternocephalicus
Linguofacial vein
Who has a tracheal bronchus (species) and what does it do?
Cows + pigs
Right cranial bronchus
Lung lobation in the horse
Left cranial and caudal
Right cranial and caudal
Accessory
Lung lobation in the cow
Left cranial (divided) and caudal Right cranial (divided), middle, caudal Accessory
Lung lobation in the pig
Left cranial (divided) and caudal
Right cranial, middle, caudal
Accessory
Comparative lung lobes in dog vs. pig, cow, horse
Pig = dog Cow = dog plus division of right cranial Horse = no division, no middle
Which species lack a bronchial vein? Where does the blood go?
Horses and cows have no bronchial vein. The blood passes through the alveolar capillary networks and returned through the pulmonary veins.
Who has a fenestrated mediastinum?
Horses +/- dogs/cats (maybe not technically fenestrated, but often effectively fenestrated)
Blood supply of the hypophysis
Internal carotid and caudal communicating arteries
