What is the main structure of the central nervous system?
Central Nervous System Structure. The CNS has three main components: the brain, the spinal cord, and the neurons (or nerve cells). Each part of the CNS plays an important role in how the body functions, and the three components of the CNS work together to take in information and control how the body responds.
What is the basic structure and function of the nervous system?
The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body’s electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system.
What are the 3 major structures of the nervous system?
The central nervous system (CNS) is made up of the brain, cerebellum and the spinal cord.
What are the parts of the central nervous system its basic job?
The central nervous system (CNS) consists of the brain and the spinal cord. Our brains have two primary functions, which are to control behavior and to regulate the body’s physiological processes.
Which of the list of structures include all of the central nervous system?
The CNS consists of the two major structures: the brain and spinal cord. The brain is encased in the skull, and protected by the cranium. The spinal cord is continuous with the brain and lies caudally to the brain. It is protected by the vertebrae.
Which of the following are the basic element of nervous system?
* The basic elements of the nervous system is the nerve cells which are produced into long processes called axons along which the nerve impulses travel. The bodies of the nerve cells may be aggregated to form ganglia while bundles of axons may form the nerves.
What are the 4 main structures of the nervous system?
The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.
What is the structural organization of the nervous system?
Divisions of the 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 statement best describes the central nervous system?
Which best describes the central and peripheral nervous systems? The central nervous system processes stimuli information the body receives, and the peripheral nervous system senses stimuli and carries out the reaction.
What structures in the central nervous system have a role in the body’s voluntary movement?
The cerebrum is responsible for conscious sensation and voluntary movement, as well as advanced functions such as thinking, learning and emotion.
What are the three basic parts of the nervous system and how are they sorted?
The human nervous system is made up of three basic parts: the central nervous system, the peripheral nervous system, and the autonomic nervous system. Without a doubt, it is the most complex part of the human body, a masterpiece of nature.
What provides structural support in the central nervous system?
Glial cells of the (a) central nervous system include oligodendrocytes, astrocytes, ependymal cells, and microglial cells. Oligodendrocytes form the myelin sheath around axons. Astrocytes provide nutrients to neurons, maintain their extracellular environment, and provide structural support.
