It is the center of all mental activity including thought, learning, and memory. Leave an answer. It receives information from the sensory organs via nerves, transmits the information through the spinal cord, and processes it in the brain. The CNS consists of the brain and spinal cord. There are three major parts to the human brain: the cerebrum, the cerebellum, and the brain stem. For example, the lymph nodes, spleen, thymus as well as the lymphatic tissue found in the small intestine (Peyer's patches) and throat (adenoid tonsils, palatine and tubal tonsils), to name a few, all represent lymphatic organs. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. Each subdivision has structural and functional characteristics that distinguish it from the others. The brain is one of the most important organs in the human body system. Organ Systems. These vital organs are surrounded and protected by the bones of the skull and vertebral column. The CNS contains the brain and spinal cord.The PNS consists mainly of nerves, which are long fibers that connect the CNS to every other . It then sends a message back through the nerves to tell the body how to react. (c) When the sense organ in our body is affected, it sends the message to the brain in the form of electrical impulses through the sensory neurons. Colloquially, the SNS governs the "fight or flight" response while the PNS controls the "rest and digest" response. The PNS consists mainly of nerves, which are enclosed bundles of the long fibers or axons, that connect the CNS to every other part of the body.
