Ans. There are three type of the muscle tissue. These are as under:-

1. Skeletal muscles tissue.

2. Cardiac muscle tissue.

3. Smooth muscles tissue.

Muscle tissue consists of cells called as muscle fibres that are specialized for contraction.  

The special features of the above muscle tissues are given as below:-

1. Skeletal muscles tissue:- These tissue attached to bones and long , cylindrical, striated fibres with many peripherally located nuclei.

They are voluntary in nature.

They are usually attached to bones by tendons.

They help in motion, posture, heat production and also in protection.

2. Cardiac Muscle tissue:- They form the wall of heart. They are also striated but involuntary. Its contraction is not consciously controlled. The cardiac muscle fibres are branched and usually have only one centrally located nucleus. They attach end to end by transverse thickening of the plasma mementos called interrelated discs.

Intercalated discs are unique feature of cardiac muscle tissue.

They help in the pumping of blood to all parts of body.

3. Smooth Muscle fibre:- A smooth muscle fibre is small, thickest in the middle and tapering at each end. It contains a single, centrally located nucleus. The fibres are involuntary and nonstriated. So they are called as the smooth.

These type of the muscles are found in the hollow internal structures such as blood vessels, airway to the lungs, stomach etc.
