incorrect
9.
Q What are the two parts of the pericardium?
incorrect
10.
Q The vertical borders of the breast are roughly ribs 2 and 6, depending on age and structure (so really those numbers mean nothing). What else is located at the rib 2 level?

incorrect
12.
Q How/where does the pericardium attach to the heart?
incorrect
13.
Q What supports the lobules in the female breast? Where are these most developed?
incorrect
14.
Q Where is the areola located in relation to underlying structures?
incorrect
15.
Q There are 15-20 lobules per gland in the female breast. What drains each lobule?
incorrect
16.

20.
Q The female breast extends roughly from the lateral border of the sternum to what point laterally?
A.
A The pos. intercostal arteries supply blood to the lateral thoracic wall. These have lateral mammary branches that reach the breast.
B.

C.
A medial mammary branches of the internal thoracic artery, and lateral mammary branches of the lateral thoracic artery (this is 2-3 times larger)
D.
A Yes, it is from the thoracoacromial artery, BUT it comes from the clavicular branch as opposed to the pectoral branch.
E.
A The int. thoracic artery is a branch of the subclavian artery, which travels parallel to the sternum, pos. to the ribs.
F.
A They are modified sweat glands. Also present are sebaceous glands of montgomery that secrete oil for lubrication.
