The Englishman coming up behind her seized her where he could, in the region of her coccyx and her left rib cage.
Fracture of the coccyx may be due to a direct blow, or may occur during parturition.
Also note how much longer and more solid the sacrum (with its attached bone, called the coccyx) is in the male pelvis.
The bone immediately below the sacrum, called the coccyx, is essentially the representative of the tail in man.
Joined to the lower end of the sacrum is the coccyx, or cuckoo-bone, a tapering series of little bones.
Running along each side of the spine, from the base of the skull to the coccyx, is a chain of nerve knots, or ganglia.
The coccyx has the importance of being a real and actual caudal appendage, reduced in man to its simplest anatomical expression.
I believe the Os coccyx gives attachment to certain muscles, but I can not doubt that it is a rudimentary tail.
The coccyx bears a distinct dorsal ridge and has a bicondylar articulation with the sacrum.
The bones were in perfect condition, even the coccyx being intact.
1610s, from Latin coccyx, from Greek kokkyx "cuckoo" (from kokku, like the bird's English name echoic of its cry), so called by ancient Greek physician Galen because the bone in humans supposedly resembles a cuckoo's beak.

The small triangular bone located at the base of the spinal column, formed by the fusion of four rudimentary vertebrae, and articulating above with the sacrum. Also called tailbone.
