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.
The dorsal root ganglia next to the spinal cord are involved with sensory function. The autonomic nervous system has autonomic ganglia that can be further divided into sympathetic and parasympathetic ganglia. The axons of neurons are typically grouped together to form nerve trunks. There are connective tissue layers that surround the peripheral nerves.
