angularis and deep facial v.
53
the external jugular vein is an _________ vein
superficial
54
There are at LEAST __ present mandibular lymph nodes
2
55
The external jugular vein (large/small) in animals
The internal jugular vein is (small/large) in animals
external: HUGE
internal: small, covered by connective tissue

Cephalic v.
57
Parotid lymph center
what is the lymph center
group of lymph nodes that drain a common area
58

drain ventral, mandibular
**remember we can palpate**
59
are the mandibular gland technically located in the head or in the neck
neck area, ventral to the wings of the atlas
60
what 3 veins around the mandibular gland
maxillary
linguofacial
facial
61
Parotid gland is located in around _____ and the opening is in _______
around the ear
opening in the papilla ~4th premolar
62
what kind of fibers does Mylohyoideus have? Geniohyoideus?
Geniohyoideus= longitudinal
Mylohyoideus= transverse; most ventral boundary of the oral cavity
63
what is the lingual artery is a branch of the ______
what does it supply
external carotid
the tongue
64
what does the hypoglossal nerve innervate? what happens if its damaged
motor (GSE) for the tongue
if damaged: paralysis of the tongue
65
Function of the parathyroid gland
imbedded in the thyroid
regulate mineral in bones (Ca, P)
66
what is the origin of the Common carotid arteries
Brachiocephalic trunk
67
what does the cranial thyroid a. supply
thyroid, larynx, esophagus, trachea
68
what does the caudal thyroid a. supply
esophagus and trachea
69
The common carotid artery has very little branches. Why is this beneficial
makes it easier to manipulate during surgery to reach the vertebral column
70

left common?
right= trachea
left= esophagus
71
Do humans have a Vagosympathetic trunk? Is it easy to damage?
Humans do not have
Yes, easy to damage because it its wrapped in the carotid sheath
