Branches
The innominate artery usually gives off no branches, but occasionally a small branch, the thyreoidea ima, arises from it. Other times, it gives off a thymic or bronchial branch.
The thyreoidea ima (a. thyreoidea ima) ascends in front of the trachea to the lower part of the thyroid gland, which it supplies.
It varies greatly in size, and appears to compensate for deficiency or absence of one of the other thyroid vessels. It occasionally arises from the aorta, the right common carotid, the subclavian or the internal mammary.

Famous quotes containing the word branches:
“Go to the adolescent who are smothered in family—
Oh how hideous it is
To see three generations of one house gathered together!
It is like an old tree with shoots,
And with some branches rotted and falling.”
—Ezra Pound (1885–1972)
“Different persons growing up in the same language are like different bushes trimmed and trained to take the shape of identical elephants. The anatomical details of twigs and branches will fulfill the elephantine form differently from bush to bush, but the overall outward results are alike.”
—Willard Van Orman Quine (b. 1908)
“Certain branches cut
certain leaves fallen
the grapes
cooked and put up
for winter”
—Denise Levertov (b. 1923)
