Detailed explanation-1: -The anterior median fissure provides a groove in which the anterior spinal artery sits. From here, it provides the anterior part of the spinal cord. It is sourced from the segmental medullary arteries and the segmental spinal arteries which are sourced from the intercostal arteries.
Detailed explanation-2: -: a groove along the anterior midline of the spinal cord that incompletely divides it into symmetrical halves.
Detailed explanation-3: -Along the posterior median line of the spinal cord is a fissure called the posterior (dorsal) median sulcus. In the gray matter on the median lines lies a small central canal. This canal (filled with cerebrospinal fluid) runs the length of the spinal cord and is continuous with the ventricles of the brain.
Detailed explanation-4: -Anatomically, the spinal cord runs from the top of the highest neck bone (the C1 vertebra) to approximately the level of the L1 vertebra, which is the highest bone of the lower back and is found just below the rib cage.
