What is the function of nervous tissue for Class 9?

Nervous or the nerve tissue is the main tissue of our nervous system. It monitors and regulates the functions of the body. Nervous tissue consists of two cells: nerve cells or neurons and glial cells, which helps transmit nerve impulses and also provides nutrients to neurons.

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?

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 nerves?

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 is the function of nervous tissue quizlet?

To maintain body homeostasis with electrical signals, provide for sensation, higher mental functioning, and emotion response, and activate muscles and glands. Central nervous system and Peripheral nervous system. The PNS is divided into somatic and autonomic branches.

What is the main function of tissue?

Epithelial tissues act as coverings, controlling the movement of materials across their surface. Connective tissue binds the various parts of the body together, providing support and protection. Muscle tissue allows the body to move and nervous tissues functions in communication.

What are the 3 types of nervous tissue?

There are three types of nerves in your body: autonomic nerves, motor nerves, and sensory nerves. SOURCES: National Institute of Neurological Disorders and Stroke: “NINDS Peripheral Neuropathy Information Page.” Neuropathy Association: “About Peripheral Neuropathy: Facts.”

What are the characteristics of nerve tissue?

Nervous tissue contains two categories of cells — neurons and neuroglia. Neurons are highly specialized nerve cells that generate and conduct nerve impulses. Neuroglia are supporting cells that provide physical sport, remove debris, and provide electrical insulation.

What is nervous tissue and its types?

Structure. Nervous tissue is composed of neurons, also called nerve cells, and neuroglial cells. Four types of neuroglia found in the CNS are astrocytes, microglial cells, ependymal cells, and oligodendrocytes. Two types of neuroglia found in the PNS are satellite cells and Schwann cells.

What are the 3 main functions of 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.

Why are nerves so important?

The nervous system helps all the parts of the body to communicate with each other. It also reacts to changes both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages.

What is the main function of nerve cells?

Neurons, also known as nerve cells, send and receive signals from your brain. While neurons have a lot in common with other types of cells, they’re structurally and functionally unique. Specialized projections called axons allow neurons to transmit electrical and chemical signals to other cells.

What are the 4 types of nerves?

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.
