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.
This neuron leaves the cord through the ventral root of a spinal nerve, leaves the spinal nerve via a structure called the white ramus, then ends in an autonomic ganglion (either sympathetic or parasympathetic). In the ganglion, the visceral efferent 1 neuron synapses with a visceral efferent 2 neuron.
