What are the two parts of the central nervous system quizlet?
The CNS consists of only two parts – name them. The CNS is divided into the brain and spinal cord.
What two systems make up the nervous system?
The brain and spinal cord make up the central nervous system. Nerves everywhere else in the body are part of the peripheral nervous system.
What are the two major types of cells in the nervous system?
Cells of the Nervous System. There are two broad classes of cells in the nervous system: neurons, which process information, and glia, which provide the neurons with mechanical and metabolic support. Three general categories of neurons are commonly recognized (Peters, Palay, & Webster, 1976).
What is the main function of the peripheral nervous system?
Peripheral nerves reside outside your brain and spinal cord. They relay information between your brain and the rest of your body. The peripheral nervous system is divided into two main parts: Autonomic nervous system (ANS): Controls involuntary bodily functions and regulates glands.
What are the 3 functions of the central nervous system?
The CNS is comprised of the brain, cerebellum and spinal cord. Remaining neurons, and associated cells, distributed throughout the body form the PNS. The nervous system has three broad functions: sensory input, information processing, and motor output.
Which organ is part of our nervous system?
The brain and the spinal cord are the central nervous system. The nerves that go through the whole body make up the peripheral nervous system.
What is the relationship between the two parts of the nervous system?
If the central nervous system is the command centre of the body, the peripheral nervous system (PNS) represents the front line. The PNS links the CNS to the body’s sense receptors, muscles, and glands.
