Abstract

The objective of this chapter is to introduce the sensory organs. Humans have five basic senses following as touch, sight, hearing, smell and taste. The sensing organs associated with each sense send information to the brain to help us understand and perceive the world around us. Skin is the covering of the entire external surface of the body, including external auditory meatus and outer surface of tympanic membrane. It is continuous with mucous membrane at the orifices of the body. The ear is the organ of hearing and maintenance of balance. Eyeball is the organ of vision. It is like a spherical ball about 2.5 cm in size. It is made up of three layers such as outermost layer, middle layer, and innermost layer. In this chapter, short essay type questions are also provided.
