In any body locale where strength of interconnection is a requirement, dense connective tissues are found. Forces transmitted across tissues determine how the protein fibers are placed within each tissue type. For example, tendons and ligaments are cords of the body that must resist linear forces along their lengths.
The cervical spine in your neck is made up of seven bones called vertebrae, which are separated by discs filled with a cushioning gel-like substance. Your cervical discs both stabilize your neck and allow it to turn smoothly from side to side and bend forward to back.
Cervical. The first seven vertebrae, all in the neck. These are smaller and lightly built. Thoracic. Twelve vertebrae, each articulating with the twelve pairs of ribs. Lumbar. The lower five vertebrae, between the ribs and the sacrum.These have the largest vertebral bodies. Each of the three segments of the spine has a curve. The cervical spine and the lumbar curve both are convex anteriorly, while the thoracic spine curves the opposite way, convex posteriorly.Each vertebra is shaped a bit like a wedge to support these curves, especially noticeable with the five lumbar vertebrae.he first seven vertebrae, all in the neck.
