What is a nerve where are they found?
Nerves that connect the spinal cord with other parts of the body are called spinal nerves. The brain communicates with most of the body through the spinal nerves. There are 31 pairs of them, located at intervals along the length of the spinal cord (see Overview of Spinal Cord Disorders.
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.
What tissue are nervous tissue?
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 and its types?
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.
Where is nervous tissue not found?
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. It contains highly specialised unit cells called nerve cells or neurons.
Are nerves tissues?
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.
Where nervous tissue is not found?
How are nervous tissues protected class 10?
The nervous tissue are protected by skull. Nervous tissue is one of four major classes of tissues and makes up the central nervous system and the peripheral nervous system.
Is nervous tissue a connective tissue?
Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The word “neuroglia” means “nerve glue.” These cells are nonconductive and provide a support system for the neurons. They are a special type of “connective tissue” for the nervous system.
Where are epithelial tissues located?
the body
Epithelial tissues are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands.
Is nervous tissue found in tendons?
The internal tendon bulk is thought to contain no nerve fibres, but the epitenon and paratenon contain nerve endings, while Golgi tendon organs are present at the myotendinous junction between tendon and muscle.
Which part is not found in central nervous system?
The correct answer is b. The satellite cells are the cell types that are not found in the central nervous system.
Where in the body are peripheral nerves found?
Peripheral nerves reside outside your brain and spinal cord . They relay information between your brain and the rest of your body. The peripheral nervous system is divided into two main parts: Autonomic nervous system (ANS): Controls involuntary bodily functions and regulates glands.
Where are the nerve cells found in the body?
There are four types of glial cells in the central nervous system; astrocytes, oligodendrocytes,microglial cells, and ependymal cells. Astrocytes are found in the brain and spinal cord, and have a starlike appearance.
Which cells make up nervous tissue?
As previously mentioned, in addition to neurons, glial cells are the other major cell type that make up the nervous system. Glial cells are also called neuroglia. Although they are not as well known as neurons, they make up about 90\% of cells within the CNS.
Where are involuntary or smooth muscles found?
The work of smooth and cardiac muscles is involuntary. Smooth muscle can also be found in the respiratory tract, the reproductive systems of both women and men, the ciliary muscle of the eye, and the urinary bladder. Most blood and lymphatic vessels in the human body are lined with smooth muscle cells, allowing them to constrict and dilate.
