In many ways, the T12 is a hybrid vertebra with the anatomical features of both a thoracic and lumbar vertebra. The T12 vertebra is located in the spinal column of the thoracic (or trunk) region inferior to the T11 vertebra and superior to the first lumbar (L1) vertebra.

What are the 5 sections of the spine?

The spine is composed of 33 bones, called vertebrae, divided into five sections: the cervical, thoracic, and lumbar spine sections, and the sacrum and coccyx bones.

Your spine serves many important functions, including connecting your brain to other parts of your body and providing structural support. You can’t live without a spine. Some conditions, such as SCI and spina bifida, can affect the spinal cord, leading to symptoms like partial or complete loss of movement or sensation.

What are the 3 regions of the spine?

The normal anatomy of the spine is usually described by dividing up the spine into three major sections: the cervical, the thoracic, and the lumbar spine. (Below the lumbar spine is a bone called the sacrum, which is part of the pelvis). Each section is made up of individual bones, called vertebrae.

How is spine divided?

The spine itself has three main segments: the cervical spine, the thoracic spine, and the lumbar spine. The cervical is the upper part of the spine, made up of seven vertebrae (bones). The thoracic is the center portion of the spine, consisting of 12 vertebrae. The lower portion of the spine is called the lumbar spine.

How many bones are in the spine?

The average person is born with 33 individual bones (the vertebrae) that interact and connect with each other through flexible joints called facets. By the time a person becomes an adult most have only 24 vertebrae because some vertebrae at the bottom end of the spine fuse together during normal growth and development.

How many spinal nerves are there?

There are 31 pairs of spinal nerves and roots. Eight pairs of cervical nerves exit the cervical cord at each vertebral level. One member of the pair exits on the right side and the other exits on the left. The first cervical root exits above the C1 vertebra.

What is the spinal canal made of?

The vertebral canal is composed of the vertebral foramen located in the cervical, thoracic, and lumbar vertebrae. The vertebral or spinal canal typically ends at the level of the L2 vertebra, where the spinal cord gives off multiple branching spinal nerve and nerve rootlets known as the cauda equina.
