2. The spinal cord is a single structure, whereas the adult brain is described in terms of four major regions: the cerebrum, the diencephalon, the brain stem, and the cerebellum. The brain sends messages via the spinal cord to the body's peripheral nerves, which control the . In this section, we focus on the peripheral nervous system; later, we look at the brain and spinal cord. The brain and the body. The nervous system is an organ system in charge of sending messages to and from the brain and spinal cord to and from all parts of the body. In this section, we focus on the peripheral nervous system; later, we look at the brain and . It also controls the body's senses and memories. name the three parts of the brain. Name the part of the central nervous system that is displayed in this tissue section. These exclusively contain neurons with a pseudounipolar neuronal arrangement. Histological and Anatomical Review of the CNS The Central Nervous System. The nervous system tells the heart to beat, controls the lungs to breathe, controls the movement of the body, and how to think and learn. The nervous system absorbs information from its environment, analyses and interprets it, and then responds. The nervous system can be divided into two separate systems - the central nervous system and the peripheral nervous system. •Reabsorbed constantly by arachnoid mater and drained into veins. Further, the different parts of the brain work in the form of coordinated functional systems rather than as individual parts. All cells of the nervous system are made of neurons. 5. The brain contains about 86 billion nerve cells (neurons) and trillions of "support cells" called glia. The CNS is comprised of the brain and spinal cord; the PNS connects the CNS to the rest of the body. I can describe the functions of the nervous system. Match. The skull and the spine The two main parts of the central nervous system, the brain and the spinal cord are protected by the skull and the spinal column.skul. The term peripheral nervous system (PNS) refers to any part of the nervous system that lies outside of the brain and spinal cord. The brain is encased in the skull, and protected by the cranium. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body. The brain and spinal cord are inside your skull and vertebrae (the vertebrae make up your backbone). Peripheral Nervous System The peripheral nervous system is made up of thick bundles of axons, called nerves, carrying messages back and forth between the CNS and the muscles, organs, and senses in the periphery of the body . The spinal cord and the body. But at the same time, they function in an integrated manner in complex human actions.
