Question

identify the structure that has the arrow pointing to it.

anterior grey horn
posterior grey horn
dorsal root ganglia
central canal
anterior median fissure

Explanation:

• The posterior grey horn (also known as the dorsal horn) of the spinal cord is involved in sensory processing. In a cross - section of the spinal cord, it is located towards the back (posterior) part of the grey matter.
• The anterior grey horn (ventral horn) is associated with motor neurons. The dorsal root ganglia are outside the spinal cord proper (contain cell bodies of sensory neurons). The central canal is a small channel in the center of the spinal cord filled with cerebro - spinal fluid. The anterior median fissure is a groove on the anterior (front) surface of the spinal cord.

Answer:

Posterior grey horn
