Question

Our sensory organs are quite delicate organs, we should therefore take full care of them. Suggest, in brief, the ways in which we should take care of, the these organs.

Answer 1

• Eyes are organs of the visual system. They provide organisms with vision, the ability to receive and process visual detail, as well as enabling several photo response functions that are independent of vision. Eyes detect light and convert it into electro-chemical impulses in neurons.

• The ear is the organ of hearing and, in mammals, balance. In mammals, the ear is usually described as having three parts—the outer ear, middle ear, and the inner ear. The outer ear consists of the pinna and the ear canal.

• The tongue is a muscular organ in the mouth of most vertebrates that manipulates food for mastication and is used in the act of swallowing. It is of importance in the digestive system and is the primary organ of taste in the gustatory system.

• A nose is a protuberance in vertebrates that houses the nostrils, or nares, which receive and expel air for respiration alongside the mouth. Behind the nose are the olfactory mucosa and the sinuses.

• The skin is the largest organ of the body, with a total area of about 20 square feet. The skin protects us from microbes and the elements, helps regulate body temperature and permits the sensations of touch, heat, and cold.

• The human eye is an organ which reacts to light and pressure. As a sense organ, the mammalian eye allows vision. Human eyes help to provide a three dimensional, moving image, normally colored in daylight.
• The semicircular canals or semicircular ducts are three semi-circular, interconnected tubes located in the innermost part of each ear, the inner ear. The three canals are the horizontal, superior and posterior semicircular canals. The human nose is the most protruding part of the face that bears the nostrils and is the first organ of the respiratory system. The nose is also the principal organ in the olfactory system.
