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 are the two types of tissue found in the nervous system?
There are two types of nervous tissue : 1) neurons and 2) neuroglia . Neurons (Figure 5) actually transmit the impulses. Neuroglia (Figure 6) provide physical support for the neural tissue , control tissue fluids around the neurons , and help defend the neurons from invading organisms and xenobiotics .
What are the types of nervous tissues?
Nervous tissue is grouped into two main categories: neurons and neuroglia. Neurons, or nerves, transmit electrical impulses, while neuroglia do not; neuroglia have many other functions including supporting and protecting neurons.
What are the three 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 are the 2 different types of neurons?
Types of neurons

- Motor neurons. …
- Interneurons. …
- Neurons in the brain.

What is an example of nervous tissue?
Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. … The cells in nervous tissue that generate and conduct impulses are called neurons or nerve cells. These cells have three principal parts: the dendrites, the cell body, and one axon.
Where is nervous tissue not found?
Solution : Tendons are the connective tissue, which join skeletal muscels to bones, hence nervous tissue is absent is them .
What is nervous tissue with diagram?
Nervous tissue is one of four major classes of tissues. It is specialized tissue found in the central nervous system and the peripheral nervous system. It consists of neurons and supporting cells called neuroglia. The nervous system is responsible for the control of the body and the communication among its parts.
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 nervous tissue 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 difference between nervous tissue and nervous system?
Nervous tissue: It is a tissue made up of a number of nerve cells. It works to perform a particular function. … Nervous system: It is a group of nervous tissue that manages a number of nervous tissue.It has a definte function that is to manage the tissues that transmit messages to the whole body.
Which body part is not composed of nervous tissue?
So, the correct answer is ‘Tendons’
What is the basic unit of nervous tissue?
The basic unit of the nervous system is a nerve cell, or neuron. The human brain contains about 100 billion neurons.
What type of neurons are in the brain?
There are three major types of neurons: sensory neurons, motor neurons, and interneurons. All three have different functions, but the brain needs all of them to communicate effectively with the rest of the body (and vice versa).
What is the most common type of neuron?
Interneurons. Interneurons are neural intermediaries found in your brain and spinal cord. They’re the most common type of neuron. They pass signals from sensory neurons and other interneurons to motor neurons and other interneurons.
What is the gap between two neurons called?
Synapse, also called neuronal junction, the site of transmission of electric nerve impulses between two nerve cells (neurons) or between a neuron and a gland or muscle cell (effector). A synaptic connection between a neuron and a muscle cell is called a neuromuscular junction.
