Integration and communication are the two major functions of nervous tissue. Nervous tissue contains two categories of cells — neurons and neuroglia
What are the 2 types of nervous tissue and their functions?
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 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 the nervous system?
First, the basic functions of the nervous system are sensation, integration, and response . Secondly, control of the body can be somatic or autonomic—divisions that are largely defined by the structures that are involved in the response.
What are the 2 major types of cells that form 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.
What are the three basic functions of the nervous system?
Remaining neurons, and associated cells, distributed throughout the body form the PNS. The nervous system has three broad functions: sensory input, information processing, and motor output .
What are the 3 types of nervous tissue?
- Endoneurium. ...
- Perineurium. ...
- Epineurium.
What is nervous tissue class 9?
They are highly specialised for being stimulated and then transmitting the stimulus very rapidly from one place to another. Brain,spinal cord,nerves are made up of nervous tissue. Nervous tissue contain unit cell called nerve cell or neurons. The impulses travel one one neuron to another neuron.
How many types of nervous tissue are there?
Nervous tissue is composed of neurons and supporting cells called neuroglia, or ” glial cells.” There are six types of neuroglia . Four are found in the central nervous system, while two are found in the peripheral nervous system.
What are the two main types of neurons?
- Sensory neurons. Sensory neurons help you: ...
- Motor neurons. Motor neurons play a role in movement, including voluntary and involuntary movements. ...
- Interneurons.
What is nervous system and its functions?
The nervous system is the major controlling, regulatory, and communicating system in the body . It is the center of all mental activity including thought, learning, and memory. Together with the endocrine system, the nervous system is responsible for regulating and maintaining homeostasis.
What is nervous system with diagram?
The Central Nervous System is the integration and command center of the body. It consists of the brain, spinal cord and the retinas of the eyes. The Peripheral Nervous System consists of sensory neurons, ganglia (clusters of neurons) and nerves that connect the central nervous system to arms, hands, legs and feet.
What is the most important part of the nervous system?
The brain and the spinal cord make up the central nervous system. The nervous system is the most complex and highly organized body system. It receives information from the sensory organs via nerves, transmits the information through the spinal cord, and processes it in the brain.
Which organ is formed by nervous tissue?
The nervous system consists of the brain, spinal cord , sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.
What is the difference between the nervous tissue and nervous system?
The main difference between nervous tissue and nervous system is that the nervous tissue is one of the four types of tissues in animals , making up the nervous system, whereas the nervous system is the complex system of nerves and cells, which coordinate the functions of the body in response to different responses.
What are the characteristics of nervous tissue?
- Nervous tissue compensates for nervous system CNS and PNS.
- Contains two different cells – neurons and glial cells.
- It consists of dendrites, ends of the cell body, axons, and nerves.
- The neurons secrete chemical neurotransmitters that stimulate other neurons as a result of stimuli.
