Course

The nerve to quadratus femoris is a sacral plexus nerve. It arises from the ventral divisions of the fourth and fifth lumbar and first sacral nerves: it leaves the pelvis through the greater sciatic foramen, below the piriformis muscle, and runs down in front of the sciatic nerve, the superior and inferior gemellus muscles, and the tendon of the obturator internus, and enters the anterior surfaces of the muscles; it gives an articular branch to the hip-joint.

gollark: Applications have to handle them differently, and the kernel does too.
gollark: There's a significant difference between "send datagram" and "push to a stream" and, i don't know, "wait for an inbound TCP connection".
gollark: Still, though, I don't think having all this stuff as read/writeable "files" when the semantics are different is good.
gollark: I basically just want to receive packets from ff02::aeae port 44718 on all interfaces and send them too, and I can't tell what operations that maps to.
gollark: It does seem like the primitives are very irritating to make this multicasting thing work properly with.
