Spinal cord regions, diagram
Spinal cord regions. Diagram of a sagittal section through the human skull and backbone, showing the five main regions of the spinal cord and the numbered nerves associated with them. The regions are colour-coded, from top to bottom: cervical (green), thoracic (orange), lumbar (purple), sacral (red), coccygeal (green). The spinal nerves branch out from the spinal cord to supply different regions of the body. They general ennervate adjacent areas, but sometimes can supply areas relatively far away, and trapped nerves in the neck and lower back can cause pain in the arms and legs. Humans have 31 spinal nerves

EDITORS COMMENTS
This print showcases a detailed diagram of the spinal cord regions, providing an insightful glimpse into the complex anatomy of the human body. In this sagittal section through the skull and backbone, we can observe five distinct regions of the spinal cord, each color-coded for clarity. From top to bottom, these regions are identified as cervical (green), thoracic (orange), lumbar (purple), sacral (red), and coccygeal (green). The numbered nerves associated with each region further emphasize their significance in our nervous system. As these spinal nerves branch out from the cord, they supply various parts of our body. While they generally innervate adjacent areas, it is fascinating to note that sometimes they can extend their reach to relatively distant locations. However, this intricate network also highlights how trapped or compressed nerves in specific areas such as the neck or lower back can cause discomfort and pain in seemingly unrelated parts like arms and legs. With 31 spinal nerves present in humans, this illustration serves as a valuable resource for those interested in biology and neurology alike. Its anatomical accuracy combined with vibrant colors make it an engaging piece of art that captures both scientific precision and aesthetic appeal.
