The term synapse was first discovered in 1897 by neurophysiologist Charles Sherrington. The gap between two neurons across which impulses are conducted is known as a synapse. Synapse is a structure that permits a neuron to pass an electrical or chemical signal to another cell. It is important for neuronal function. Thus, the correct answer is option B.
Destruction of the anterior horn cells of the spinal cord would result in loss of
Anterior horn cells are the ventral (front) grey matter section of the spinal cord which contains motor neurons that affect the skeletal muscles. It is also known as anterior grey column, ventral horn. The anterior grey column is the column where the cell bodies of alpha motor neurons are located. The destruction of the anterior horn cells of the spinal cord would result in loss of voluntary motor impulses because it is mainly related to motor impulses.
