Ruminant and Porcine Thorax - Comparative Anatomy Flashcards
Describe the line of costal pleural reflection in the cow
from 8th costochondral junction to the middle of the 11th rib, reaches the angle of the 13th rib just below the edge of the iliocostalis muscle
Describe the line of costal pleural reflection in sheep
from 9th costochondral junction to the middle of the last rib, to the cranial border of transverse process of L1
Describe the line of costal pleural reflection in the goat
from 6th costochondral junction to the level of the ventral border of the last rib
Describe the mediastinum of the cow and goat
thick and intact
Describe the mediastinum of the sheep
weaker than cow/goat
stronger than the horse
Describe the unique features of the bovine right lung
the asymmetry of the right lung causes a deviation of both the cranial and caudal mediastinum from the left
the caudal part meets the diaphragm in a saggital plane that bisects the reticulum
(note relevance of Hardware Disease)
In which species is the cupula pleura present?
cows, sheep and horses
Where are the cardiac notches located in ruminants?
left: 3-5 ICS
right: 3-4 ICS
Describe the cranial lobes of the ruminant lungs
both cranial lobes are subdivided into cranial and caudal parts
Describe the cranial lobes of the lungs of pigs
only the left cranial lobe is subdivided into cranial and caudal parts
Which species have an additional tracheal bronchus?
ruminants and pigs
Describe the lobation of the bovine lungs
prominant intralobular lobation
Describe the lobulation of the goat’s lungs
less conspicuous intralobular lobation than the cow
Describe the lobation of the ovine lungs
barely any intralobular lobation
Describe the lobation of the porcine lung
intralobular lobation is less conspicuous
