types of spinal instrumentation. The Kaneda device is used to treat fractured thoracic or lumbar vertebrae when it is suspected that bone fragments are present in the spinal canal.
The human adult vertebral column consists of 26 bones. There are 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, and 2 that are collections of fused bones, the sacrum and the coccyx. An infant may have 32, 33, or 34 spinal bones present at birth.
There are normally thirty-three (33) vertebrae in humans, including the five that are fused to form the sacrum (the others are separated by intervertebral discs) and the four coccygeal bones that form the tailbone. The upper three regions comprise the remaining 24, and are grouped under the names cervical (7 vertebrae), thoracic (12 vertebrae) and lumbar (5 vertebrae), according to the regions they occupy. This number is sometimes increased by an additional vertebra in one region, or it may be diminished in one region, the deficiency often being supplied by an additional vertebra in another. The number of cervical vertebrae is, however, very rarely increased or diminished. With the exception of the first and second cervical, the true or movable vertebrae (the upper three regions) present certain common characteristics that are best studied by examining one from the middle of the thoracic region.

An African human is just like a human from any other part of the world. All humans have 33 Vertebrae split into 5 regions. The top 7 are called the Cervical Vertebrae, then Next 12 are called the Thoracic Vertebrae, then the 5 Lumbar Vertebrae. All the vertebrae mentioned so far are free individual bones that are joined at their Vertebral Bodies by special cartilagenous joints called Intervertebral Disks. The next region down is the Sacral region (or Sacrum) within which all 5 vertebrae are fused to form effectively one bone. And the final 4 vertebrae are also fused to oneanother to form a structure known as the Coccyx. This adds up to a total of 33 vertebrae, present in all healthy human being. In plainer terms, healthy babies are born with 33 vertebrae, and through fusion a healthy adult is left with 26.

Bugs fall within Insecta. As all insects present exoskeletons and do not have vertebrae, they are invertebrates.
Vertebral Column (26 bones) Location: Posterior midline of axial skeleton Description: Composed of 33 vertebrae & intervertebral disks (C2-S1), distributed in 5 regions • (C) 7 cervical vertebrae • (T) 12 thoracic vertebrae • (L) 5 lumbar vertebrae • (S) 5 sacral vertebrae, fused into single bone (sacrum) • (Co) 3-5 coccygeal vertebrae, variably fused • Has series of curvatures along length Also known as: "Spinal column", "spine", or "backbone"
