week 9 Flashcards
costodiaphragmatic recess location
caudal to the basal border of the lung
costomediastinal recess
between ventral border of lung and ventral body wall
transversus thoracis muscle courses
from sternum to the costochondral regions
transversus thoracis functions in
expiration
pulmonary ligament function
anchoring the caudal lung lobes to the mediastinum
ruminant left lung lobes
cranial and caudal parts of cranial lobe; caudal lobe
ruminant right lung parts
cranial lobe with cranial and caudal parts; caudal lobe; accessory lobe
accessory lobe location
between the mediastinum and the plica vena cava
hilus of lung
where pulmonary vessels enter
sternal lymph node location
cranioventral region of the thorax near the internal thoracic artery
cranial mediastinal lymph node location
cranial to the heart
middle mediastinallymph nodes location
dorsal to the base of the heart but ventral to the carina of the trachea
caudal mediastinal lymph node location
betwen the thoracic aorta and esophagus and are quite pronounced in ruminants
thoracic duct
enters thoracic cavity through the aortic hiatus of the diaphragm and courses cranially on the right side of the animal between the right azygous vein and the aorta to about the level of T6 or T7 in horse and T5 in ruminants; the duct crosses obliquely over the esophagus towards the left side of the trachea and courses to the thoracic inlet
thoracic duct typically drains into
cranial vena cava or left external jugular vein
