Anatomical terminology |
The superficial inguinal ring is bounded below by the crest of the pubis; on either side by the margins of the opening in the aponeurosis, which are called the crura of the ring; and above, by a series of curved intercrural fibers.
- The inferior crus (or lateral, or external pillar) is the stronger and is formed by that portion of the inguinal ligament which is inserted into the pubic tubercle; it is curved so as to form a kind of groove, upon which, in the male, the spermatic cord rests.
- The superior crus (or medial, or internal pillar) is a broad, thin, flat band, attached to the front of the pubic symphysis and interlacing with its fellow of the opposite side.
