What is the importance 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 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 are the tissues in the nervous system?

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 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 main features of nervous tissue?

Key Points

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 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 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 is nervous tissue and its function?

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.

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 the difference between nervous system and nervous tissue?

Nervous tissue is made up of nerve cells called as neurons, whose primary function is to carry messages from one body part to another. The different nervous tissues which work together in the body make up the nervous system, which is essential for proper functioning of the body.

What is nervous tissue made of?

Nervous tissue is made up of cells called neurons and neuroglia.

Does the heart have nervous tissue?

Normally, we do not think of the heart as a sensory organ, but it possesses a rich supply of heterogeneous nerve endings that communicate the mechanical and chemical state of the heart to the brain via both the vagus nerves and the spinal cord.

What is the main cell of the nervous tissue?

Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the “conducting” cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell.
