In relation to the great vessels arising from the heart, what does the sternal angle
demarcate?
Give this one a try later!
The sternal angle demarcates the bifurcation of the
pulmonary trunk, bifurcation of the trachea, the junction of
the ascending aorta and aortic arch, and the junction of the
aortic arch and the descending aorta.
What is the thorax comprised of?
Give this one a try later!
The thorax is comprised of a bony cage made up by the vertebral column,
ribs and sternum and intercostal spaces filled with intercostal muscles,
, veins, arteries, and nerves.
What organs are retroperitoneal?
Give this one a try later!
SAD PUCKER
S = suprarenal glands (adrenal glands)
A = aorta/IVC
D = duodenum (2nd segment)
P = pancreas
U = ureters
C = colon (ascending and descending)
K = kidneys
E = esophagus
R = rectum
What are the 4 major anastamoses that occur in the abdomen?
Give this one a try later!
i) right and left gastric arteries
ii) right and left gastroepiploic arteries
iii) superior and inferior pancreaticoduodenal arteries
iv) middle colic and left colic (or marginal) arteries
What are the two types of valves in the heart?
Give this one a try later!
, 1) Tri- (right atrioventricular) and bicuspid (left
atrioventricular) valves
2) Semilunar valves (pulmonary and aortic valves)
What is the mesentery?
Give this one a try later!
The mesentery describes the two layers of peritoneum
reflected from the posterior abdominal wall that suspend
the organs.
How are the intercostal muscles layered?
Give this one a try later!
The most superficial layer of the intercostal muscles are the
external intercostal muscles (hands in pockets), followed by
the internal intercostals (hands in axilla of opposite side),
and finally the innermost intercostal muscles (rib to rib
muscles). The transversus thoracis (running from sternum to
inner surface of costal cartilages) and subcostal muscles
(spans 2-3 ribs) also help to make up the deepest layer of
intercostal muscles.
The van structures supplying the intercostal muscles travel
between the internal and innermost intercostal muscles.
