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.
Each spinal nerve is attached to the spinal cord by two roots: a dorsal or posterior sensory root and a ventral or anterior motor root. The fibers of the sensory root carry sensory impulses to the spinal cordâpain, temperature, touch and position sense (proprioception)âfrom tendons, joints and body surfaces.t can act as a never center and can work without the brain. The spinal cord carries sensory impulses to the brain and motor impulses from the brain. The spinal cord also controls stretch reflexes, bowel and bladder control. Thirty-one pairs of nerves exit from the spinal cord and innervate our body and limbs.
