The Tale Of The Tail Bone

It is highly possible that the human ancestors descended from a species that once had a scum bag. There are no real answers just theories as to why humans have a coccyx, tailb ace. It has been said that the coccyx on a human is a fundamental structure, import that it is the remains of a body part that we once may have had during the process of evolution. Like the name suggest the tail raise could of real well have been a tail at iodin time. It is unclear as to how long it would have developed or grown. Which begs the question, did humans ever have a protruding tail? To understand that theory we have to understand the coccyx.
The coccyx is alike cognise as the human tailbone. It is a small, triangular bone located at the lower end of the vertebral column. The coccyx it attached at the end of the sacrum through a vestigial disc and is as well connected to the sacrum with ligaments. There is very exceptional movement between the coccyx and the sacrum.
The small coccyx consists of common chord to five (most often four) coccygeal vertebrae that usually begun fusing by the days of 26. The coccyx provides an attachment site for a number of ligaments and for musclebuilder that constricts the anal opening. The first two coccygeal vertebrae have transverse processes and unfused vertebral arches.



The prominent laminae of the first coccygeal vertebra are known as the coccygeal cornua; they curve the meet the cornua of the sacrum. The coccygeal vertebrae do not complete their fusion until late in adulthood. In males, the adult coccyx points anteriorly, whereas in females, it points inferiorly. In very fourth-year people, the coccyx may fuse with the sacrum. (Martini et al. 168).
Only about five percent of the populations have a coccyx in one piece, separate from the sacrum. The anterior surface of the coccyx is slightly concave. It is also marked with three transverse grooves which indicate the junction of contrasting segments. It gives attachment to the anterior sacrococcygeal ligament...If you want to get a fully essay, order it on our website: Orderessay
