Quick Answer: 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 the 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 are the two main functions of nervous tissue?

Key Takeaways

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 are the three functions of nervous tissue?

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.

What is the function of nervous tissue quizlet?

– Is found in the brain, spinal cord, and nerves and is characterized by the ability to conduct electrical signals called action potentials. – Nervous tissue consists of neurons, which are responsible for its conductive ability, and support cells called neuroglia.

What are 5 functions of the nervous system?

5 Major Functions of Nervous System

  • Detection of both internal environment and external environmental changes of the body.
  • Conduction of Information.
  • Integration of Information.

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 nerves and what are their functions?

A nerve is a bundle of fibers that receives and sends messages between the body and the brain. The messages are sent by chemical and electrical changes in the cells, technically called neurons, that make up the nerves.

What is the most important function of the nerves?

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 three functions of the nervous system quizlet?

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 is the main function of the nervous system and how is it structured?

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).
