The vertebrae is located at the top of your body and ends at your lower back.
A sacral vertebra is any of the five vertebrae which are fused to form the sacrum.
right above the tail bone
back
There are 5 different portions of the vertebra starting from top to bottom: 7 Cervical Vertebra 12 Thoracic Vertebra 5 Lumbar Vertebra 5 Sacral Vertebra 4 Coccygeal Vertebra
The body or centrum of the vertebra bears the most weight
This means that the lumbar vertebra #5 (the last one) is very small and not completely developed. S1 is the first sacral and is the same. The sacrum is composted of 5 fused vertebra. This may have produced some weakness in muscle movement or skin sensation.
a vertebra is more closely defined according to what part of the spine it's in. It may be cervical (neck), thoracic (chest), lumbar (abdomen), or sacral (hips).
Yes it's a bone. What else could it possibly be? There are about 33 during early development, and 26 by adulthood. Vertebrae in the sacral and coccygeal region fuse together.

5th lumber vertebrae and first sacral vertebra.
The projecting anterior edge of the body of the first sacral vertebra is called the sacral promontory etc
The fifth lumbar vertebra articulates with the first fused sacral vertebra of the pelvic girdle.
Cervical, thoracic, lumbar, sacral and coccygeal.
Yes, if the vertebra is in the lumbar region or the sacral region.

The anatomy books show what are normally seen, five vertebra... There are many variants in anatomy, and someone with four lumbar vertebras isn't abnormal, just someone who is a little different, but still normal. You might have something we call a "transitional" vertebra, such as an extra thoracic vertebra merged into a lumbar, or maybe a lumbar vertebra fused with a sacral vertebra... Still normal...
Bottle nosed dolphins (Tursiops truncatus) have 60-65 total vertebra (7 cervical vertebra, 13 thorasic, 14 lumbar, 0 sacral, and 26 caudal) in their spinal column. The first two vertebra (axis and atlas) are fussed.

A posterior annular tear is a tear in the ligament fibers that cover the inner core of a disc. The discs separate each vertebra in your spine. A posterior annular tear in the L5-S1 discs indicates the location in which these tears occur. L5 is the fifth and lowest of the lumbar vertebra and the S1 is the first and highest sacral vertebra.
