what is sacralizatoin of the fifth lumbar vertebra?

In addition to the first answer, yes it is where the lowest vertebrae has fused with the sacral bone.  (Meaning tail bone.)  It's not an uncommon thing really.  \n\nIn January of 2005 I had my L4/L5 and L5/S1 (Meaning Lumbar vertebrae #5 and my Sacral bones) fused together intentionally.  This is an area that gets a tremendous amount of stress and pressure, leading to the most common form of lower back pain and back trauma.  It seems your body did the natural thing to strengthen that region - by connecting the two bone sections together to give you a stronger lower back which will help avoid nerve damage from a bulging or ruptured disc.\n\nIt sounds more frightening than it is...but it seems your body had a good defense mechanism.  As long as you're not suffering sciatic pain and muscle weakness in your legs, there's noting to worry about.

I would look here for your answer and/or a link that could get you your answer http://en.wikipedia.org/wiki/Vertebrate\n\nGood Luck!!!

First off, it's only the number of _cervical_ (neck) vertebrae of mammals that is fixed at 7, not all the other vertebral types. There are exceptions, such as the tree sloths with 6 or 9 vertebrae, and a manatee species with 6, but the number 7 is consistent in most species of mammals, from giraffes (although there was an interesting question about it here) to dwarf shrews. \n\nA recent hypothesis (1999) about the fixed nº of cervical vertebrae is related to evolutionary developmental (evo-devo) aspects. Apparently, in mammals the genes that regulate the development of the skeleton (Hox genes) are also linked to the proliferation of cell lines (which is in turn related to the origin of cancer). Thus, any change in the nº of vertebrae could bring about deletereous (negative) changes in the control of cell multiplication, and would be constrained by natural selection because although the fixed nº of cervical vertebrae is not particularly advantageous, the possibility of tumor development is decidedly disadvantageous.\n\nAnd with respect to canislupus' question: If there is such a constraint, maybe the different number of cervical vertebrae in sloths and manatees gives advantages that offset the potential problems. In the case of sloths, I can easily see that more vertebrae enable greater rotation angle of the head (these animals are very impressive when they move). In the case of manatees, I cannot think of an evident advantage, but then again, I don't know much about manatees.\nSee the article at the first link.\n\n------------\nUpdate: I've checked other sources and it appears that both manatees and sloths share one trait: low basal metabolism. This could allow changes in the regulatory Hox gene without the threat of cancer (see second link)\n------------\nUpdate 2: Canislupus, this is new knowledge for me too. That's why I like Answers :-)

G'day Richard K,\n\nThank you for your question.\n\nDeep-seated is correct. It means deeply-rooted or deep beneath the surface.\n\nI have attached sources for your reference.\n\nRegards

...\n\nThe bony arches of the vertebrae have two types of projection: one, called the spinous process, extends backwards from the arch in the mid-line (it is these spinous processes which are felt all down the back); the other, the transverse processes, extend laterally on each side from a position posterior to the intervertebral foramen.\n\nIf one now considers the vertebral column as a structural unit, one sees the column of vertebral bodies anteriorly, joined by the intervertebral discs as bricks are joined by mortar, with the bony arches behind. These bony arches have paired pedicles which enclose the intervertebral foramina on each side just behind the vertebral bodies. Farther back on each side one encounters the transverse processes, and finally in the mid-line of the back, the spinous processes. The whole column is bound together with various ligaments of great strength, on the anterior and posterior surfaces of the vertebral bodies and on the bony arches, their processes, and their joints. The muscles further strengthen and cushion the vertebral column.\n\nWithin the vertebral column, the circles formed by the bony arches described above are aligned to constitute a canal, called the spinal canal. The spinal canal contains the spinal cord, the trunk of nerves which is in continuity with the brain above. Neither the brain nor the spinal cord are in contact with the bones which protect them. These delicate nerve structures are completely enveloped by three concentric membranes, the meninges; respectively, the dura mater, the arachnoid, and the pia mater.\n\n...

they are called Dimples of Venus or Sacral Dimples... "The two dimples in most everyone's back (historically known as the "dimples of Venus") are where the sacrum joins the hipbones, called the sacroiliac joint"\n\nThe phrase 'dimples of Venus' refers to the pair of sagittally symmetrical indentations sometimes visible on the human lower back, just above to the gluteal cleft. The dimples are directly superficial to the two sacroiliac joints, the sites where the sacrum attaches to the ilium of the pelvis.\n\nThis term, while ostensibly informal, is not strictly slang, but is a historically accepted name within the medical profession for the superficial topography of the sacroiliac joints. \n\nDimples of Venus are rapidly gaining cultural momentum as a feature which men find particularly attractive in females

Interesting question. In anatomy, they name structures typically but you are looking for the names to the space outside the body above or around structures. The lumbar region is where you would find the small or hallow of the back and the lateral to the group of bones that forms the tarsus is where the small of the ankle would be located. \n\nThe suprasternal notch is actually part of the sternum and therefore named. The hallows both of the back and the ankle are formed by the articulations or the way several things fit together on the body and therefore not. They are not, in an anatomical sense, specific enough to anything.

There is no F.  The vertebrae are divided into C (cervical), T (thorax), L (lumbar), S (sacral) and O (coccyx)

L4 or L5 region - could be a strain of the joint but could also be disc damage \n\nclearly it is impinging on your nerves - ice the area and use ibuprofen \n\nseek medical or chiropractor help
