Almost all the joints between vertebrae are movable. The joints between the cervical vertebrae and lumber vertebrae have fairly good movement. Between thoracic vertebrae only you have less movement. But then they do move on each other.
between the vertebrae
Humans typically have 33 vertebrae, but only 24 of these are movable. The first 7 are cervical vertebrae in the neck, followed by 12 thoracic vertebrae in the mid-back, and 5 lumbar vertebrae in the lower back. Below the lumbar region are the sacrum and coccyx, which are fused vertebrae.
The lower lumbar vertebrae are the most stress bearing vertebrae.
Cartilaginous are slightly movable, but the most prominent type of movable joints are synovial joints, such as the knee and shoulder, which are very movable.
A typical horse has around 54 to 60 vertebrae in its spine. This includes 7 cervical vertebrae (neck), 18 thoracic vertebrae (chest), 6 lumbar vertebrae (lower back), 5 sacral vertebrae (pelvis), and 16-18 coccygeal vertebrae (tail). The exact number can vary slightly among individual horses.

between the vertebrae
The spine is composed of 33 movable segments called vertebrae. These vertebrae are divided into five regions: cervical (7 vertebrae), thoracic (12 vertebrae), lumbar (5 vertebrae), sacrum (5 fused vertebrae), and coccyx (4 fused vertebrae).
The lumbar vertebrae are the largest segments of the movable part of the vertebral column
The human spine typically consists of 33 vertebrae, but 26 of these are often referenced when considering the vertebrae that contribute to the movable sections of the spine. This includes 7 cervical, 12 thoracic, and 5 lumbar vertebrae. The remaining vertebrae are fused into the sacrum and coccyx. These 26 vertebrae play a crucial role in providing support, flexibility, and protection for the spinal cord.
allow only slight movement.The joints present between the vertebrae of the backbone and the joints between the ribs and the breastbone are the examples of slightly movable joints.
Classified by type of cartilage: Fibrous joints-immovable such as sutures in the skull. Cartilaginous- partially movable such as vertebrae. Synovial- Freely movable such as knee and finger joints. Classified by functional use: synarthrosis - permits little or no mobility (mostly fibrous joints as in the skull). amphiarthrosis - permits slight mobility (mostly cartilaginous joints as with vertebrae) diarthrosis - freely movable (synovial joints used in body movement)
Your spine is an elaborate unit structurally consisting of 33 vertebrae, 24 movable and 9 fused, and 23 intervertebral discs. In between each of the 24 movable vertebrae, except between C1/C2 (atlas and axis), discs are situated. These discs allow for the mobility, curvature, and shock absorption qualities of the spine. The vertebrae themselves are the main structures that protect the spinal cord via the posterior arch, consisting of pedicles and laminae. Therefore, the vertebrae protect the integrity of the spinal cord, but the discs are the structures responsible for the motion of the spine.
The 12th vertebra, known as the lumbar vertebra (L1), is not fused with any other vertebrae. It is the last of the five lumbar vertebrae in the lower back and is characterized by its larger size compared to the thoracic vertebrae above it. Unlike the sacral vertebrae, which are fused together, L1 remains a separate and movable vertebra, allowing for flexibility and support in the lumbar region.

What are movable fin and movable exhausts use for? [Improve]
No, the backbone is not a joint. It is made up of individual bones called vertebrae that are connected by ligaments and do not move independently. The backbone provides structure and support to the body and protects the spinal cord.
