coccygeal nerve การใช้

The coccygeal nerve is the 31st pair of spinal nerves.
In the nervous system, Rhazes stated that nerves had sacral, and 3 coccygeal nerves.
The nerves divide into branches and the branches from different nerves join with one another, some of them also joining with lumbar or coccygeal nerve branches.
However, adhering to the outer surface of the filum terminale are a few strands of nerve fibres which probably represent rudimentary second and third coccygeal nerves.
