Sacral Canal

The sacrococcygeal canal (lat. canalis sacrocavernosus) is an unpaired paired canal from the group of two-osseous canals of the pelvic ring. Has a short and wide stroke. Due to this, the sacrococcygeal canal is located at an angle, which is most often 25°. Thanks to which it exits through the third intervertebral foramen of the sacral canal. It contains sciatic vessels, a plexus of nerves and a cavernous sinus, as well as other formations. The sacral muscle (m. sacrococcygeus), which ends in the coccyx, entwines only the upper part of the sacrococcygeal canal. Some researchers classify the sacrococcygeal canal as an intrapelvic vessel.
