Which of the following horns has a spinal cord tract?
A. Anterior horn
B. Posterior horn
C. White matter
D. Grey matter

Hint: A horn is that part of the nervous tissue that has a spinal tract. Besides, it receives sensory info such as touch and sensation. These horns have sensory neurons in them that help perceiving.

Complete step by step answer: -Anterior horn cells are the ventral (front) gray matter section of the neural structure that contains motor neurons that affect the skeletal muscles. It's additionally referred to as anterior gray column, ventral horn. The anterior gray column is that the column wherever the cell bodies of alpha motor neurons are placed. The destruction of the anterior horn cells of the neural structure would end in loss of voluntary motor impulses as a result of it's primarily associated with motor impulses.
-The posterior horn is that part of substantial grey matter that has a spinal tract. It receives sensory data such as touch and sensation via sensory neurons from totally different components of the body. It's conjointly referred to as a dorsal horn due to its presence in the dorsal aspect of the body.
-White matter consists of the nerve fibers or the axons that are encircled with the physiologist Cells secreting the medullary sheath. Because the medullary sheath is formed from the fats, it seems white in color, and therefore the myelinated nerve fibers are known as the nervous tissue.
-The cerebrum is the largest part of the brain that helps within the interpretation of the information and generates nerve response. The outer portion of the neural structure seems gray and it's referred to as grey matter. It seems gray as a result of its sizable amount of neuron cell bodies and unmyelinated nerve fiber. The inner portion of the brain is thought of as nerve tissue because it contains terribly less somatic cell bodies and cases.

Hence, the correct answer is a posterior horn which is option B.

Note: Poliomyelitis typically referred to as infantile paralysis or poliomyelitis is an associated communicable disease caused by the enterovirus that affects the brain and medulla spinalis. In about 0.5 percent of cases, there's muscle weakness leading to an associate inability to maneuver.
