Quick Answer: What is the structure and function of nervous tissue?

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 structure of nervous?

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 are the structural characteristics of nervous tissue?

It consists of nerve cells or neurons, all composed of an axon. Axons are long stem projections that arise from the cell and are responsible for interacting with other cells called the Target cells, thus passing on impulses. The main component is the cell body that contains the nucleus, cytoplasm, and organelles.

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 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 is the function of nervous system?

Your nervous system is your body’s command center. Originating from your brain, it controls your movements, thoughts and automatic responses to the world around you. It also controls other body systems and processes, such as digestion, breathing and sexual development (puberty).

What is the structure of nervous tissue class 9?

1)It consist of cell body which contain central nucleus and cytoplasm from which long thin hair like part arises called dendrons. 2)The axon is a single,long,cylindrical structure that conduct electrical impulses away from neuron’s cell body. 3)The dendrons further branches into dendrites.

What are the main structures of a neuron?

A neuron has three main parts: dendrites, an axon, and a cell body or soma (see image below), which can be represented as the branches, roots and trunk of a tree, respectively. A dendrite (tree branch) is where a neuron receives input from other cells.

What is a neuron write the structure and function of a neuron?

Nervous system cells are called neurons. They have three distinct parts, including a cell body, axon, and dendrites. These parts help them to send and receive chemical and electrical signals.

What is neuron write the structure and function of neuron Class 9?

Neuron comprises dendrite, axon and cell body. Dendrites receives messages from the surrounding and sends it to the cell body. Cell body consists of nucleus, mitochondria and other organelles. Axon transmits the message away from the cell body and pass it to the next receiving neuron.

What is the function of nerve cell class 8?

Function of nerve cells: The function of the nerve cell is to receive and transfer messages, it helps to control and coordinate the working of different parts of the body.

What are the three major functions of nervous tissues?

Functions of the Nervous System

The nervous system has 3 main functions: sensory, integration, and motor.

What is the function of nervous tissue in the skin?

The sensory nerves in the epidermis serve to sense and transmit heat, pain, and other noxious sensations. When these nerves are not functioning properly they can produce sensations such as numbness, pins-and-needles, pain, tingling, or burning.
