What is the largest physical feature on earth? I only need the largest, its for my geography class. Also which is the smallest of the 4 major oceans. I can't find these answers anywhere, not even in my geography book.
Dorsal roots are fascicles of axons in the spinal cord that receive sensory information from the skin, muscle, and visceral organs that enter through the a point of entry called the dorsal root entry zone.
Structure [edit]. The axons of dorsal root ganglion neurons are known as afferents. In the peripheral nervous system, afferents refer to the axons that relay sensory information into the central nervous system (i.e. the brain and the spinal cord).
