APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The spine is made up of 33 vertebrae. More than 13 million neurons are found in the spine. Adults only have 26 vertebrae because bones fuse together as we age. There are 220 ligaments in the spine.

Detailed explanation-2: -Vertebrae are the 33 individual bones that interlock with each other to form the spinal column. The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2). Only the top 24 bones are moveable; the vertebrae of the sacrum and coccyx are fused.

Detailed explanation-3: -The vertebral column is also called the spinal column or backbone. It’s made up of 33 vertebrae that are separated by spongy disks and classified into 4 distinct areas. The cervical area consists of 7 bones in the neck.

Detailed explanation-4: -In humans, it is composed of 33 vertebrae that include 7 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 4 coccygeal.

Detailed explanation-5: -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. The cervical section of the spine is made up of the top seven vertebrae in the spine, C1 to C7, and is connected to the base of the skull.
