Question

Q.8 Compare on the basis of matrix and function in between Epithelial, connective, Muscular & Nervous

tissues.​

Answer 1

Answer:

The connective tissue is composed of different cells and a larger amount of extracellular matrix. The cells of the epithelial tissue are arranged cellular sheets either in single or multiple layers. The cells in the connective tissue are scattered throughout the matrix in no particular arrangement.

Answer 2

Epithelial Tissue

$\bigstar$ Epithelial tissue is commonly known as Epithelium.

$\bigstar$ Epithelium is made up of one or more layers which lines the internal and external surface of many body parts.

$\bigstar$ Cell are compactly packed with little intercellular matrix.

$\bigstar$ Epithelial tissue is classified into two groups - simple epithelium and compound epithelium.

Connective Tissue

$\bigstar$ Connective tissue is the most abundant tissue in the body of complex organisms.

$\bigstar$ Connective tissue is made up of three components : Matrix, cell and fibres.

$\bigstar$ Matrix is mainly a mixture of protein and polysaccharides.

$\bigstar$ Except blood in all connective tissue the cells secrete fibres made of structural proteins called elastin. These fibres provide strength, elasticity and flexibility to the tissue.

Muscular tissue

$\bigstar$ All types of movement done by the body is with the help of muscular tissue.

$\bigstar$ They are made up of long cylindrical and fibre like cells.

$\bigstar$ Muscle fibres in a muscle are present in the form of bundles.

$\bigstar$ The muscle fibres help in exhibiting contraction and relaxation.

Nervous tissue

$\bigstar$ Nervous tissue is specialised to transmit message in the body. They have specialised cells called neurons.

$\bigstar$ Brain, spinal cord and nerves are all composed of nervous tissue.

$\bigstar$ The neuroglial cell which constitutes the rest of the Neural system protects and supports neurond.
