2748008: Spinal cord structure (body structure)

SNOMED CT Concept\Body structure (body structure)\Anatomical or acquired body structure (body structure)\Anatomical structure\...

\An anatomical structure that consists of the maximal set of organ parts so connected to one another that together they constitute a self-contained unit of macroscopic anatomy, distinct both morphologically and functionally from other such units. Together with other organs, an organ constitutes an organ system or a body part. An organ is divisible into organ parts but not organs (examples: femur, biceps, liver, heart, aorta, sciatic nerve, ovary).\Brain and spinal cord structure (body structure)\Spinal cord structure

\Body region structure\Structure of back of trunk and/or neck (body structure)\This volume includes the spinal column, its spaces and contents, notably the spinal canal, spinal meninges and spinal cord. It also includes the muscles associated with the spine within (and including) the anterior and posterior thoracolumbar fascia and its equivalent nuchal fascia in the neck. This region also includes the spinal ventral (anterior) and dorsal (posterior) roots, the dorsal root (spinal) ganglions and the spinal nerve trunks.\Structure of vertebral column and/or spinal cord (body structure)\Spinal cord structure
