kyphosis, lordosis and scoliosis
Overall, sacral vertebrae problems are not common in horses. However, it is possible for the sacral vertebrae to become fractured, dislocated or infected, all of which can compress the pelvic limb spinal nerves that run through the sacral vertebrae.
The median sacral crest on the sacrum is a bony ridge formed by fusion of sacral vertebrae, indicating where the individual vertebrae once were. In contrast, the median sacral crest on lumbar vertebrae does not exist, as lumbar vertebrae do not fuse in the same way as sacral vertebrae.

The lumbar vertebrae come next, followed by the sacral.
the sacral vertebrae, and think it's 4 to 5 that are fused together
sacrum and coccyx
A sacral vertebra is one of the bones in the spine located in the lower back, just below the lumbar vertebrae. There are typically five sacral vertebrae that are fused together to form the sacrum, which connects the spine to the hip bones. The sacral vertebrae play a role in supporting the weight of the body and protecting the spinal cord.
No, lampreys do not have sacral vertebrae. They are jawless fish belonging to the class Agnatha and possess a primitive vertebral column made up of cartilaginous structures called arcualia, rather than true vertebrae like those found in more advanced vertebrates. Consequently, they lack the specialized sacral vertebrae that support the pelvic girdle in higher vertebrates.
The five types of vertebra are the:cervical vertebrae (neck)thoracic vertebrae (chest)lumbar vertebrae (back)sacral (pelvis)coccyx (tailbone)
sacral hiatus
The sacral vertebrae, typically comprising five fused vertebrae (S1-S5), form the sacrum, a triangular bone located at the base of the spine. This fusion provides structural stability and support for the pelvis, connecting the spine to the hip bones. Additionally, the sacral vertebrae have unique features such as the sacral canal and foramina, which allow for the passage of nerves and blood vessels. Their fusion and shape contribute to weight distribution during standing and movement.
