What is the function of the obturator foramen?

Answer 1

According to Gray's Anatomy, the obturator foramen is contained by sometimes called pelvic region of the trunk) is the lower part of the trunk, between the abdomen and the lower limbs (legs).

The pelvis includes several structures:

The bony pelvis, or pelvic skeleton, the part of the skeleton connecting the sacrum region of the spine to the femurs.

Subdivided into the pelvic girdle (the two hip bones, which are part of the appendicular skeleton) and the pelvic region of the spine (sacrum, and coccyx, which are part of the axial skeleton)

The pelvic cavity, typically defined as a small part of the space enclosed by the pelvic skeleton, delimited by the pelvic brim above and the pelvic floor below; alternatively, the pelvic cavity is sometimes also defined as the whole space enclosed by the pelvic skeleton, subdivided into:

The greater or false pelvis, above the pelvic brim

The lesser or true pelvis, below the pelvic brim

The pelvic floor or pelvic diaphragm, below the pelvic cavity

The perineum, below the pelvic diaphragm

In the human, the pelvic skeleton is formed in the area of the back (posterior dorsal), by the sacrum and the coccyx (the caudal portion of the axial skeleton), and laterally and anteriorly (forward and to the side), by a pair of hip bones, the lower extremity, (parts of the appendicular skeleton).

In an adult human being, the pelvic skeleton is thus composed of three large bones, and the coccyx (3-5 bones);

However, before puberty, each hip bone consists of three discrete (separate) bones - the ilium, ischium, pubis - that have yet to fuse at adulthood; thus, in puberty, the human pelvic skeleton can comprise more than 10 bones, depending upon the composition of the person's coccyx.

Answer 2

The obturator foramen is a hole created by the ischium and pelvis bone of the pelvis. Its function is to let nerves and muscles pass through.
