Describe the gross anatomical features of a cross section of spinal cord

What will be an ideal response?


Gross anatomical features of the cross-sectioned spinal cord include the anterior median fissure (a deep groove along the anterior or ventral surface); the posterior median sulcus (a shallow longitudinal groove); white matter (dominated by myelinated axons); gray matter (composed of cell bodies of neurons, neuroglia, and unmyelinated axons); the central canal (a passageway containing cerebrospinal fluid); a posterior root of each spinal nerve (axons of neurons whose cell bodies are in the posterior root ganglion); the anterior root of each spinal nerve (the axons of motor neurons that extend into the periphery to control somatic and visceral effectors); posterior root ganglia (contain cell bodies of sensory neurons); and spinal nerves (contain the axons of sensory and motor neurons).
