Is epithelial tissue nervous tissue?
Note that epithelial tissue originates in all three layers, whereas nervous tissue derives primarily from the ectoderm and muscle tissue from mesoderm. View this slideshow to learn more about stem cells.
How is the nervous tissue different from other tissues?
Nervous tissue the most complex of the four basic tissues, is composed of nerve cells, the neurons and supporting cells, the neuroglia. Unlike other basic tissues, the nervous tissue almost lacks intercellular substance.
What is the major difference between epithelial tissue and other types of tissue in the body?
The main difference between epithelial and connective tissue is that epithelial tissue lines the cavity and the surfaces of organs and blood vessels throughout the animal body whereas connective tissue supports, connects and separates different types of tissues and organs in the body.
What is meant by epithelial tissue?
An epithelium is a type of animal tissue made up of densely packed cells (called epithelial cells) that rest on a basement membrane. Its function is to act as a covering or lining of various bodily surfaces and cavities.
What is the difference between neurons and neuroglia?
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 characteristics of the 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.
Which cells form the nervous tissue?
Nervous tissue is composed of neurons and supporting cells called neuroglia, or ” glial cells.”
What is nervous tissue class 9th?
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 is the difference between epithelial tissue and connective tissue class 9?
Epithelial tissue is avascular with no blood supply. Connective tissue is vascular and thus are rich in blood vessels, except for cartilages and tendons. Epithelial tissue also doesn’t have nerve supplies. Connective tissue is innervated except for cartilage.
