APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -In a human vertebral column, there are normally 33 vertebrae. The upper 24 pre-sacral vertebrae are articulating and separated from each other by intervertebral discs, and the lower nine are fused in adults, five in the sacrum and four in the coccyx, or tailbone.

Detailed explanation-2: -The human spine consists of 24 articulating vertebrae grouped into cervical, thoracic, and lumbar regions. Nine more vertebrae make up the sacrum and coccyx. Typical vertebrae consist of the anterior vertebral body and the posterior section, which contains the vertebral foramen through which the spinal cord passes.

Detailed explanation-3: -The adult vertebral column consists of 24 vertebrae, plus the sacrum and coccyx. The vertebrae are divided into three regions: cervical C1–C7 vertebrae, thoracic T1–T12 vertebrae, and lumbar L1–L5 vertebrae.

Detailed explanation-4: -The 24 movable vertebrae are the 7 cervical (neck), 12 thoracic (back of chest), and 5 lumbar (loin). The remaining vertebrae include 5 fused sacral, and between 3 and 5 fused caudal.

Detailed explanation-5: -The first 24 vertebrae are called “articulating” and the last 9 are called “fused.” In addition to the distrinction between articulating and fused, vertebrae are divided into five different categories. They are: cervical veretebrae, thoracic vertebrae, lumbar vertebrae, sacrum and coccyx.
