APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -This is true of all cervical vertebrae except C7, whose transverse foramina contain only accessory veins. Another feature unique to the cervical vertebrae is the bifid spinous process (See “physiologic variants” section), which may serve to increase surface area for muscle attachment.

Detailed explanation-2: -The main anatomical characteristics of a typical cervical vertebra that separate it from other types of vertebrae are the small size, transverse foramina, saddle-shaped body, and bifid spinous process (Fig.

Detailed explanation-3: -Cervical vertebrae have unique anatomical features that distinguish them well from other spine areas. Their bifid spinous processes provide a space for nuchal ligamental attachment, and triangular vertebral foramina accommodate the thicker cervical spinal cord.

Detailed explanation-4: -6 – Cervical Vertebrae: A typical cervical vertebra has a small body, a bifid spinous process, transverse processes that have a transverse foramen and are curved for spinal nerve passage. The atlas (C1 vertebra) does not have a body or spinous process.

Detailed explanation-5: -The transverse foramen (foramen transversarium) of cervical vertebrae is an opening that is occupied by the vertebral artery and vein in the first six vertebrae and only the vertebral vein in the seventh. The vertebral artery is of particular importance because it serves the brain and spinal cord.
