what are the major functions of nervous system?
14349
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.

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.

Central Nervous System The brain is the body's main control center. The main function of the CNS is the integration and processing of sensory information. It synthesizes sensory input to compute an appropriate motor response, or output.

Functions of the nervous system are sensory input, integration, control of muscles and glands, homeostasis, and mental activity. Nerves carry the signals to the brain. Cells comprising the central nervous system and the peripheral nervous system are classified as neural tissue.

The nervous system controls: Sight, hearing, taste, smell, and feeling (sensation). Voluntary and involuntary functions, such as movement, balance, and coordination. The nervous system also regulates the actions of most other body systems, such as blood flow and blood pressure.

Of all the body systems, the nervous system is the major control system of homeostasis. It provides monitoring, response, and regulation of all systems in the human body and other organisms. It functions from the tiny level of individual cells to affecting the whole body at once. ... This is the process of homeostasis.

Divisions of the Nervous System 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.

The nervous system is a highly integrated system. The nervous system has three overlapping functions based on sensory input, integration, and motor output. At a more integrative level, the primary function of the nervous system is to control and communicate information throughout the body.

THE BASIC FUNCTIONAL UNIT OF THE NERVOUS SYSTEM IS THE NEURON. WHAT IS THE MAJOR FUNCTION OF THIS CELL TYPE? TO TRANSMIT AND GENERATE MESSAGES (NERVE IMPULSES) FROM ONE PART OF THE BODY TO ANOTHER.

The main function of the central nervous system is to process information from stimuli and respond. process information from responses and sense stimuli. sense stimuli and cause reactions in the body.

The somatic nervous system is part of the peripheral nervous system. Major functions of the somatic nervous system include voluntary movement of the muscles and organs and reflex movements. In the process of voluntary movement, sensory neurons carry impulses to the brain and the spinal cord.

Key Points The nervous system is a highly integrated system. The nervous system has three overlapping functions based on sensory input, integration, and motor output. At a more integrative level, the primary function of the nervous system is to control and communicate information throughout the body.

The nervous system helps the body to respond to internal and external stimuli. Sometimes the stimuli can be dangerous so the nervous system also protects the body. The basic unit of the nervous system is the neuron.

What does the nervous system do? The nervous system receives information about what is happening both inside and outside your body. It also directs the way in which your body responds to this information and helps maintain homeostasis.

Central Nervous System The main function of the CNS is the integration and processing of sensory information. It synthesizes sensory input to compute an appropriate motor response, or output.

The autonomic nervous system functions to regulate the body's unconscious actions. The sympathetic nervous system's primary process is to stimulate the body's fight or flight response.
