Then, two axial sections of the spinal cord and adjacent structures allow the organisation of a spinal nerve to be displayed with its various branches (sensitive posterior root, anterior motor root, meningeal branch, muscular branches, intercostal nerves) and represent the different spaces and meninges covering the spinal cord (epidural space, subdural space, subarachnoid space, pia mater, spinal dura, arachnoid spinal). White matter looks white because of the myelin sheath covering its axons. Learn anatomy faster and Start Now < Note that not all of the spinal nerves arise from the cord at the level of the vertebrae between which they pass. Because the spinal nerves contain both sensory and motor fibers, they are considered a mixed nerve, as opposed to either a sensory or motor nerve. Last Updated 01 March, 2023. This online quiz is called THORACIC SPINAL CORD (CROSS SECTION, VENTRAL VIEW). The gray matter forms the interior of the spinal cord; it is surrounded on all sides by the white matter. The final diagram represents a reflex arc. The arterial supply of the spinal cord is shown on three different illustrations: an anterolateral view of the thoracic spine showing the emergence of the anterior spinal artery from the root and intercostal arteries), an axial section showing the branches of costal arteries destined for spinal cord and muscle and finally an overview of the A pair of transverse processes extend laterally from the vertebral arch while a spinous process protrudes posteriorly from the posterior of the arch. The plexuses are complex networks, with four or more spinal nerve rami contributing to each of the four main plexuses, and with several nerves arising from each. In various regions of the body, the anterior rami from several spinal nerves join together and then branch again, in a complex network of nerves called a plexus. This gray matter occupies a butterfly-shaped cross-section in this mature spinal cord. 22 terms.
