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 ventral root contains efferent (motor) fibers that carry messages from the spinal cord to the effectors. Cell bodies of the efferent fibers reside in the spinal cord gray matter. These roots become nerves that innervate (transmit nerve impulses to) muscles and organs throughout the body.ensory neurons connect sensory receptors to the CNS. The CNS processes the signal, and transmits a message back to an effector organ (an organ that responds to a nerve impulse from the CNS) through a motor neuron. The PNS has two parts: the somatic nervous system and the autonomic nervous system.
