wide, deep crease along the ventral surface of the spinal cord
anterior median fissure
The anterior median fissure is a deep groove that runs along the midline on the underside of the spinal cord. It separates the spinal cord into symmetrical left and right halves. This fissure is a critical landmark that allows for easy identification of the ventral (front) aspect of the spinal cord. It is an essential anatomical feature in the study of neuroanatomy and is particularly significant in understanding spinal cord injuries. The anterior median fissure provides a useful reference point for spinal cord surgeons who need to access specific regions of the spinal cord during surgical procedures. Additionally, it is also important to note that the anterior median fissure has connections to various sensory and motor pathways distributed throughout the spinal cord. Thus, any damage to this structure can have considerable implications for neural function, including motor and sensory deficits.
