Vertebrae are the bones that comprise the spine of animals with backbones.
Earthworms do not have bones, vertebrae and thus are invertebrates. in=not + vertebrate=bones/vertebrae
The vertebrae consist of the vertebral body, spinous process, transverse process, and articular processes. There are 33 vertebrae in total, including 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 5 sacral vertebrae (fused into the sacrum), and 4 coccygeal vertebrae (fused into the coccyx).
Irregular bones.
There are irregular bones, these bones are your vertebrae
Both humans and giraffes have the same number of neck vertebrae, which is seven. However, in giraffes, these vertebrae are much longer, allowing for their long necks. The difference in neck length is due to the size and shape of the vertebrae rather than the number of bones.
The bones of the spine are called vertebrae. There are 33 total vertebrae in 5 regions: cervical (7), thoracic (12), lumbar (5), sacral (5), and coccygael (4). (The 5 bones of the sacral region are fused, as are the 4 bones of the coccygeal region.)
The cervical vertebrae are the spinal bones of the neck.
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.
