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.
What is the key function of nervous tissue?
Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. It stimulates muscle contraction, creates an awareness of the environment, and plays a major role in emotions, memory, and reasoning.
What is the function of the nervous tissue quizlet?
To maintain body homeostasis with electrical signals, provide for sensation, higher mental functioning, and emotion response, and activate muscles and glands.
What are the two main functions of the basic nervous tissue?
Integration and communication are the two major functions of nervous tissue. Nervous tissue contains two categories of cells — neurons and neuroglia. Neurons are highly specialized nerve cells that generate and conduct nerve impulses.
What is the function of nervous tissue for Class 9?
The main function of nervous tissue is to receive stimuli and send signals to the brain and spinal cord. These signals are sent to the muscles via the nerves.
What is nervous tissue and its function Class 9?
Class 9 Biology Tissues. Nervous Tissue. NERVOUS TISSUE. The cells of nervous tissue are highly specialized and the cells of this tissue are called nerve cells or neurons. Nervous tissue stimulates and transmits the stimulus very rapidly from one place to another within the body.

Terms in this set (3)
- sensory input. when sensory receptors monitor changes that occur both inside and outside of the body.
- integration. when sensory information is interpreted and the appropriate response is taken.
- motor output. response that is performed by effectors- muscles or glands.
What are the 4 main functions of the nervous system?
The four main functions of the nervous system are:
- Control of body’s internal environment to maintain ‘homeostasis’ An example of this is the regulation of body temperature. …
- Programming of spinal cord reflexes. An example of this is the stretch reflex. …
- Memory and learning. …
- Voluntary control of movement.
What are the 3 major functions of the 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.
