Communication and coordination system of the body. Seat of intellect and reasoning. Consists of the brain, spinal cord, and nerves. Spinal Cord Anatomy. Extends from the foramen magnum of the skull to the first or second lumbar vertebra. Provides a two-way conduction pathway from the brain to and from the brain. 31 pairs of spinal nerves arise from the spinal cord. The Nervous System: Communication. Neurons are masses of nerve cells that transmit information. Three main components:. (1) Cell Body – contains the nucleus and two extensions. (2) Dendrites – shorter, more numerous, receive information.
