What are the 12 vertebrae?
The T9, T10, T11, and T12 vertebrae form the base of the thoracic spine. The thoracic spine consists of a total of 12 segments between the cervical spine and the lumbar spine. .. Correlation between these levels of spinal cord and nerves, along with the rest of the thoracic spine, helps control the trunk.
Where is the 12th vertebra?
In many respects, T12 is a hybrid vertebra with both thoracic and lumbar anatomical features. The T12 vertebra is located in the spinal column of the thoracic (or trunk) region below the T11 vertebra and above the first lumbar vertebra (L1).
Number of vertebrae in each section of the spinal column?
The spinal column (VC) is composed of 33 vertebrae [cervical spine (C), 7; chest (T), 5; lumbar spine (L), 5; sacrum (S), 5; coccyx , 4], interconnected by intervertebral discs (excluding C1 and C2) and stabilized by the spinal ligaments.
What are 24 vertebrae?
The adult spinal column consists of 24 vertebrae, as well as the sacrum and coccyx. The vertebrae are divided into three areas: the cervical vertebrae C1 to C7, the thoracic vertebrae T1 to T12, and the lumbar vertebrae L1 to L5.
