What are the main functions 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 Points

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?

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 main function of the nerves in the nervous system?

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 five main functions of the nervous system?

Central Nervous System – what does the brain and spinal cord do?

  • maintaining homeostasis.
  • interpreting sensory information.
  • creating motor responses (movement)
  • learning.
  • thinking.
  • talking.

What are the 3 types of nervous tissue?

Your nervous system is involved in everything your body does, from regulating your breathing to controlling your muscles to sensing heat and cold. There are three types of nerves in your body: autonomic nerves, motor nerves, and sensory nerves.

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 is Class 9 muscle tissue?

Muscular tissue consists of elongated cells, also called muscle fibres. This tissue is responsible for movement in our body. Main function of muscular tissues is to provide movement to the body. Muscles contain special proteins called contractile proteins, which contract and relax to cause movement.

Why the blood is called connective tissue?

Blood is considered a connective tissue because it has a matrix. The living cell types are red blood cells, also called erythrocytes, and white blood cells, also called leukocytes. … Erythrocytes (red blood cells), the predominant cell type, are involved in the transport of oxygen and carbon dioxide.

What are the 3 basic 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.

What is nervous system with diagram?

The nervous system has two main parts: The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.

What is the basic structure and function of the nervous system?

The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body’s electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system.

What is the function of human nervous system?
