common carotid artery, recurrent laryngeal nerve, vagosympathetic trunk, tracheolymphatic duct
what is one function of the nuchal ligament?
supports the horse’s heavy head during grazing
what is the jugular groove bordered by?
sternocephalicus ventrally
brachiocephalicus dorsally
Did the dog have a subclavius and omohyoideus muscle?
No
Why is venipuncture performed in the cranial 1/2 of the external jugular vein?
Because the omohyoideus muscle lies behind the external jug in this area preventing injection into the common carotid artery

What is Viborg’s triangle an important landmark for?
surgical approach to an enlarged guttural pouch

Pathway of otis the oats?
esophagus –> stomach –> duodenum –> jejunum –> ileum –> base of the cecum –> body of the cecum –> apex of the cecum –> back out to the right ventral colon –> sternal flexure –> left ventral colon –> pelvic flexure –> left dorsal colon –> diaphragmatic flexure –> right dorsal colon –> transverse colon –> descending colon –> rectum
