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 nervous system comprises of the nerves, brain, and the spinal cord.
What does the nervous tissue do in the nervous system?
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 3 types of nervous tissue?
Neurons, or nerves, transmit electrical impulses, while neuroglia do not; neuroglia have many other functions including supporting and protecting neurons.
What tissues are in the nervous system?
Nervous tissue, present in both the CNS and PNS, contains two basic types of cells: neurons and glial cells. A glial cell is one of a variety of cells that provide a framework of tissue that supports the neurons and their activities.
What are two differences between nervous and muscle tissue?
Muscle and nervous tissues rely on electrical activity to function. Muscle tissue generates force to provide movement, and nervous tissue is responsible for transmitting electrical and chemical signals throughout the body. Muscle and nervous tissues are considered excitable tissues.
Where is nervous tissue not found?
1 Answer. (c) Tendons are the connective tissue, which join skeletal muscles to bones, hence nervous tissue is absent is them. Nervous tissue is specialised to transmit messages within our body.
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.
How is nervous tissue formed?
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.
Which is the defining feature of nervous tissue?
Nervous tissue is characterized as being excitable and capable of sending and receiving electrochemical signals that provide the body with information. Two main classes of cells make up nervous tissue: the neuron and neuroglia (Figure 4.5. 1 The Neuron).
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 are the 3 major organs of the nervous system?
The nervous system in a human is made of the brain, spinal cord, sensory organs and all the neurons that serve as communication channels between the various organs of the body.
What are the two major subdivisions of the nervous system?
The nervous system as a whole is divided into two subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS).
What do both nervous tissue and muscle tissue have in common?
Nervous and muscular tissue both has the capability to sense and react to electrochemical stimuli.
Which tissue is responsible for the movement in our body?
The tissue responsible for movement in our body is the muscular tissue. Structurally, muscular tissue are elongated and are made up of several fibres of muscle cells.
What type of muscle tissue is only found in the heart?
Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control. Smooth muscle fibers are located in walls of hollow visceral organs, except the heart, appear spindle-shaped, and are also under involuntary control.
