What are the 3 components 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 nervous system with diagram?
The Central Nervous System is the integration and command center of the body. It consists of the brain, spinal cord and the retinas of the eyes. The Peripheral Nervous System consists of sensory neurons, ganglia (clusters of neurons) and nerves that connect the central nervous system to arms, hands, legs and feet.
What are the two major divisions of the nervous system?
The nervous system as a whole is divided into two subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS).
What is the main function of the nervous system quizlet?
The primary function of the nervous system is to collect a multitude of sensory information; process, interpret, and integrate that information; and initiate appropriate responses throughout the body. Name the main parts of the nervous system.
Why is the nervous system important quizlet?
The nervous system is one of the most important systems of the body: controls and coordinates the functions of all other systems, making them work harmoniously and effectively. Principle parts are the brain, spinal cord, and nerves.
What is the main function of the nervous system?
The nervous system is the major controlling, regulatory, and communicating system in the body. It is the center of all mental activity including thought, learning, and memory. Together with the endocrine system, the nervous system is responsible for regulating and maintaining homeostasis.
What are the two parts of the nervous system quizlet?
The Nervous System is divided into two parts. What are they? 1) The CNS (Central Nervous System) and 2) The PNS (Peripheral Nervous System. The CNS consists of only two parts – name them.
What are the common signs and symptoms of nervous system disorders quizlet?
Signs and symptoms include: neck and back stiffness, lethargy, visual disturbances, muscle aches, mental confusion, coma and death. Tonic clonic (grand mal)- loud cry, fall to floor, loss of consciousness, stiff body, biting of tongue, cyanosis, incontinence, amnesia of event.
What are the two components of the central nervous system quizlet?
The central nervous system is comprised of the brain and the spinal cord.
What is nervous system and its function?
The nervous system is involved in receiving information about the environment around us (sensation) and generating responses to that information (motor responses). The nervous system can be divided into regions that are responsible for sensation (sensory functions) and for the response (motor functions).
What are the three main parts of the nervous system and what is their function?
The Central and Peripheral Nervous Systems
The nervous system has three main functions: sensory input, integration of data and motor output.
What are the three main functions of a nervous system?
The nervous system has three broad functions: sensory input, information processing, and motor output. In the PNS, sensory receptor neurons respond to physical stimuli in our environment, like touch or temperature, and send signals that inform the CNS of the state of the body and the external environment.
