Explanation:

Aim: Preparation of temporary slide of animal tissues and their study.

Principle: Group of similar type of cells that perform a specific function, is called a

tissue. Tissues are organised in a specific proportion and pattern to form different

organs. There are four basic types of tissues : (i) Epithelial, (ii) Connective,

(iii) Muscular and (iv) Nervous.

The epithelium or epithelial tissue provides a covering or lining for some

parts of the body. Connective tissues have special function of linking and

supporting other tissues or organs of the body. Muscular tissue plays an active

role in all movements of the body. Nervous tissue controls the body's

responsiveness to changing conditions within and outside the body.

Requirement: Live material/concerned tissue, beakers, glass slides, coverslips,

watch glasses, dropping bottle, dropper, required stain, glycerine, NaCl solution

(0.9% w/v), needle, forceps, brush, toothpick, water, wash-bottle, dissecting tray,
