Sacrum
The vetebrae of the lower back are called lumbar vertebrae. Lower than that, the vertebrae are fused together in the sacrum, and the lowest part of the spine is the tailbone or coccyx.
There are 5 regions in the spine:cervical (7 vertebrae)thoracic (12)lumbar (5)sacral (5 fused)coccygeal (4 fused)
An animal with a backbone is called a vertibrate.
The sacrum is located in the lower part of the back, between the two pelvic bones. It is a triangular-shaped bone situated at the base of the spine, just above the tailbone (coccyx).

The back bone, or vertebral column, is made up of bones called vertebrae. There are 33 vertebrae in 5 regions: cervical (7 bones), thoracic (12), lumbar (5), sacral (5 fused), coccygeal (4 fused).
Spinal vertebra are called just that. There are subdivisions: cervical (neck), thoracic (chest), and lumbar (lower back). There are two sets that have fused in the adult: the sacrum and the coccyx (tail bones).
The vertebrae in the lower back are called the Lumbar vertebrae. They are L1, L2, L3, L4 and L5.
The vetebrae of the lower back are called lumbar vertebrae. Lower than that, the vertebrae are fused together in the sacrum, and the lowest part of the spine is the tailbone or coccyx.
the calvarium of the adult scull is fused, in the fetus the bones making up the skull are not fused (not joined together), also the're actually quiet a lot of space around the bones - called fontanelles or "soft spots" on a baby's head that you can feel on the back of the head in many babies until 6-9 months or so and on the front of many babies until 15-18 months or so.

vertebrae
What is often called the spine refers to a group of bone known as the vertebral column. This column is composed of vertebrae, the sacrum, and the coccyx. 2nd Answer: The spine is more specifically composed of the neck bones, or "C" vertebrae, so-called because their true names are "Cervical". There are 5 of these, the top two being also called the Atlas and the Axis. Next, named after the thorax of the body are the thoracic, or "T" vertebrae. There are 12 of these, T-1 through T-12. The small of the back, or Lumbar area, is composed of 5 "L", or Lumbar bones. The two spinal section between the 2 rear bones of the hips is actually part of the spine: The Sacrum. There are usually 5 "S" or Sacral vertebrae, and they are usually all fused together in adulthood. They sit like a wedge between the hipbones. And at the very bottom are the 3 or 4 bones of the coccyx, or "Tailbone". These coccygial bones are also fused together by adulthood.
