Spinal anatomy 

encompasses the anatomy of all osseous and soft tissue structures of the spine, the spinal cordand its supporting structures.

This anatomy section promotes the use of the Terminologia Anatomica, the global standard for correct gross anatomical nomenclature. 

Overview

The spine is located in the midline posteriorly, extending from the base of the skull to natal cleft, supporting the head, shoulder girdle, rib cage, and attaching to the pelvis. 

It is composed of 24 vertebraeseparated by intervertebral discs, with additional sacral and coccygeal segments which are usually but, variably, fused. The vertebrae are grouped together into groups based on similar osteology and regional relations; cervical spine (7 vertebrae), thoracic spine (12 vertebrae), and lumbar spine (5 vertebrae). The sacrum has five fused vertebral segments and the coccyx has a further 3 to 5 vertebral segments. 

The spinal cord descends in the vertebrae within the spinal canal.

Head and neck anatomy 

is important when considering pathology affecting the same area. In radiology, the 'head and neck' refers to all the anatomical structures in this region excluding the central nervous system, that is, the brain and spinal cord and their associated vascular structures and encasing membranes i.e. the meninges. Many pathologies are confined to a particular area of the head and neck making separation of this section of the human body exceptionally useful.

Neuroanatomy 

encompasses the anatomy of all structures of the central nervous system, which includes the brain and the spinal cord, and their supporting structures.

Abdominal and pelvic anatomy 

encompasses the anatomy of all structures of the abdominal and pelvic cavities.
