Inferior
The inferior runs obliquely across the front of the piriformis and the sacral nerves to the medial side of the anterior sacral foramina, descends on the front of the sacrum, and anastomoses over the coccyx with the middle sacral and opposite lateral sacral artery.
In its course it gives off branches, which enter the anterior sacral foramina; these, after supplying the contents of the sacral canal, escapes by the posterior sacral foramina, and are distributed to the muscles and skin on the dorsal surface of the sacrum, anastomosing with the gluteal arteries.

Famous quotes containing the word inferior:
“If it is the result of a pure love, there can be nothing sensual in marriage. Chastity is something positive, not negative. It is the virtue of the married especially. All lusts or base pleasures must give place to loftier delights. They who meet as superior beings cannot perform the deeds of inferior ones.”
—Henry David Thoreau (1817–1862)
“He who is conversant with the supernal powers will not worship these inferior deities of the wind, waves, tide, and sunshine. But we would not disparage the importance of such calculations as we have described. They are truths in physics because they are true in ethics.”
—Henry David Thoreau (1817–1862)
“Few persons who have ever sat for a portrait can have felt anything but inferior while the process is going on.”
—Anthony Powell (b. 1905)
