Structure
The anococcygeal nerve arises from a small plexus known as the coccygeal plexus. It pierces the sacrotuberous ligament to supply the skin in the region of the coccyx as well as the sacrococcygeal joint.
gollark: Hmm, so it's nonvolatile and accessible to things and then contains arbitrary headers.
gollark: Well, I don't care enough.
gollark: > Laptops, notebooks and netbooks are difficult to support and we recommend to use the vendor flashing utility. The embedded controller (EC) in these machines often interacts badly with flashing, either by blocking all read/write access to the flash chip or by crashing (it may power off the machine or mess with the battery or cause system instability). Fascinating.
gollark: It does not see flash.
gollark: Possibly.
