The anterior intervertebral joints are secondary cartilaginous joints (symphysis) which are designed for strength and weight bearing.
The vertebrae are held together primarily by ligaments, which connect adjacent vertebrae, and intervertebral discs, which provide cushioning and support between them. The anterior and posterior longitudinal ligaments run along the spine, reinforcing stability. Additionally, the facet joints between the vertebrae allow for movement while maintaining structural integrity. Together, these components create a flexible yet stable spinal column.
The 33 vertebrae in the human spine are divided as follows: 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 5 sacral vertebrae (fused into the sacrum), and 4 coccygeal vertebrae (fused into the coccyx).
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.
a human being has 33 vertebrae all together including neck to spine and everything. and then for a humans neck is the same as a giraffe which is 7 vertebrae in their neck since they are both mammals the vertebrae are just different sizes.
The vertebrae are joined together by intervertebral discs, which act as cushions and allow for flexibility and movement of the spine. Ligaments, such as the anterior and posterior longitudinal ligaments, provide stability by connecting the vertebrae along their lengths. Additionally, facet joints between adjacent vertebrae enable articulation and support the spine's structural integrity. This combination of discs, ligaments, and joints allows for both mobility and support in the spinal column.

the sacral vertebrae, and think it's 4 to 5 that are fused together
There are 33 Vertebrae, starting from the top (just under skull) there are: 7 cervical vertebrae 12 thoracic vertebrae 5 lumbar vertebrae 5 sacral vertebrae (fused together) 4 coccygeal vertebrae (fused together)
remove the disc and put the two vertebrae back together. what happens to the nerve?
The 33 vertebrae in the human spine are divided as follows: 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 5 sacral vertebrae (fused into the sacrum), and 4 coccygeal vertebrae (fused into the coccyx).
The four vertebrae that are fused together are the sacral vertebrae, specifically S1 to S5, which form the sacrum. This fusion provides stability and support to the pelvis and the spine, playing a crucial role in weight-bearing and movement. In some individuals, the coccygeal vertebrae can also be fused, forming the coccyx or tailbone.
Its primary purpose is to act as a shock absorber between adjacent vertebrae. Spinal discs also act as ligaments that hold the vertebrae of the spine together

The atlas bone (named after Atlas in Greek mythology who held up the world). The first of the cervical vertebrae are the smallest vertebrae.
They are held together by ligaments.
The human spine consists of 33 individual vertebrae, categorized into five regions: cervical (7 vertebrae), thoracic (12 vertebrae), lumbar (5 vertebrae), sacral (5 fused vertebrae), and coccygeal (4 fused vertebrae). Each pair of vertebrae in the cervical, thoracic, and lumbar regions is separated by intervertebral discs that provide cushioning and allow for movement. The sacral vertebrae are fused to form the sacrum, while the coccygeal vertebrae form the coccyx, or tailbone. Together, these vertebrae protect the spinal cord and support the body's structure.
