Question

state functions of epithelial tissue, muscular tissue, nervous tissue and connective tissue

Answer 1

Hey here is your answer.


Epithelial tissue: it helps to form covering of entire surface of the body and lines the internal organs.

Muscular tissue: it helps in the movement of the body or limbs is brought about by contraction and relaxation of contractile proteins present in muscle cells.


Nervous tissue: it helps to receive message through the dendrites and send them to the axon.


Connective tissue: it helps to connect different tissue and organs. It provides support to different parts of the body by forming packing around different organs of the body.

Answer 2

Your answer :

Animal Tissue

Animals are made up of different kinds of tissues which are responsible for performing specific functions.
Example : Blood, Lymph help to carry substances like food materials, CO2, O2 etc.

On the basis of their function they perform they are classified into 4 types :

1. Epithelial Tissue

Functions :

It forms an internal lining of elementary canal another internal organs and protect these organs.
Epithelial covers the body surface as an outer layer of skin and provides protection to the tissue lining from any injury, bacterial attack and harmful chemicals.
They help to remove nitrogen waste products of the body.

2. Connective Tissue

Functions :

Connective tissue of animals serve the function of joining one tissue with the another forming a sheet and packing a material separating them from the other material.
The major function of connective tissue is binding, supportive and packing together different organs of the body.
The space between the cells is filled with a jell-like matrix which is made up of carbohydrates.
In the case of bones or cartilages the matrix is solid and in the case of blood the matrix is fluid.

3. Mascular Tissue

Functions :

The muscles of the mascular tissue are long and narrow since these cells are elongated. They are also known as muscle fibres.
It can contain one or more nucleoid.
Since the muscle cells of the body are responsible for the movement of the body parts and help in the locomotion of organisms. These movements are carried about by contraction and relaxation.
Muscles contain special proteins called contractile proteins which cause the movement.

4. Nervous Tissue

Functions :

They contain densly packed nerve cells called nueron present in brain, spinal cord and sense organ.
They help in the conduction in the pulses they receive stimulus from the body and conduct impulses which travel one nueron to another.
The signal that passes along the nerve fibre is called nerve impulse which allow us to move our muscles when we want.
The functional combination of nerve and muscle tissue is important for animals as it allows animals to move rapidly in response to stimuli.

Hope this helps.

Have a nice day =)
