In cross section of the spinal cord, the gray matter, which might remind one of a butterfly, is divided into regions know as horns. The white matter, in comparison, is divided into regions know as columns. Identify ALL of the answers that correctly match the region with the correct function. A) Letter A. is the posterior horn and is responsible for sensory processing. B) Letter C. is the anterior horn and sends motor signals to the skeletal muscles. C) Letter B. is the lateral horn and sends signals to the internal organs of the body. D) Letter D. is the posterior column, composed of the axons of ascending tracts of nervous fibers that carry sensory information to the brain. E) Letter E. is the lateral column, composed of axons of descending tracts that carry directions from the brain to the motor neurons in the appendages.
