chapter 8 textbook questions Flashcards
shark: where the cones arteriouses emerges and that same structure goes to the head is called what? what are the things that branch off of it called?
ventral aorta
afferent branchial arteries
shark: each gill is supported at its base by what?
by an epibrachial cartilage and an adductor muscle just medial to it
shark: on the anterior side of the gill arch cartilage reside fingerlike processes called what? what do they guard?
gill rakers, guarding the internal gill slit, the opening between adjacent gill bars
shark: what extends laterally from the epibranchial cartilage and is soft and fan shaped?
gill lamellae
what is the path of water in a shark?
drawn into the mouth, forced through the internal gill slits, past the lamellae and out the external gill slits
shark: the efferent branchial arteries connect to the……
dorsal aorta
shark: what is the artery loop around the gill?
efferent collector loop
shark: what artery passes along the roof of the mouth medial to the spiracle?
hyoidean artery
shark: the first of 4 major branches off the dorsal aorta is what?
celiac artery
the celiac artery runs caudally without branching until it emegeres dorsal to the stomach along the lesser curvature. here it divides into what artery to the stomach and what artery to the intestine?
gastric artery
Pancreaticomesentric artery
shark: external carotid artery is found where?
lower jaw
shark: the pancreaticomesentric artery will eventally form what as it moves into the intestine?
anterior intestive artery
shark: posterior mesentery artery goes to what?
rectal gland
shark: heptaic portal veing (the big yellow one) has three branches:
- gastric vein (with gastric artery)
- Pancreaticomesenteric veing (parallel with pancreaticomesenteric artery)
- Lienomesenteric vein
cat: the large muscular ——- left and right are covered by thin coronary arteries and veins
ventircles
cat: if you lift up the heart youll find the single blue vein called what?
post cava
cat: before the heart the large blue vein is called what?
precava
cat: what are the three regions of the aorta that are often recognized?
- aortic trunk, the base of the vessel where it leaves the heart
- the curved systemic arch
- and the long dorsal aorta
In the cat two vessels project from the systemic arch, what are they?
the first and slightly larger on the cats right side is the single brachiocephalic artery.
Next, adjacent to it, is the left, subclavian artery to the eft arm.
what are the three arteries in the cat that brach off the brachiocephalic artery?
the first two are the left and right common carotid arteries which lie next to and paralell with the trachea,
The third is is right subclavian artery that goes into the right arm
describe air flow in the cat?
air is inhaled through the external nares into the nasopharynx, the general region dorsal to the secondary palate. It then passes through the laryngopharynx into the larynx through the glottis. Air then travels down through the trachea into primary, then secondary and tertirary bronchioles.
cat: the precava splits into what two veins?
the left and right brachicephalic vein
cat: the brachiocephalic vein is then joined by a really long vein that travels to the head!
thyroud veing which turns into the external jugular vein later
cat: half way of the brachiocephalic vein is what?
vertebral vein
