The skin

The skin has a very rich supply of sensory receptors . these detect stimuli that enable us to fell touch , pressure, pain, cold and heat .the skin can therefore be considered to be a sense organ, though it is not specialized in detecting only one type of stimuli like the other sense organs.
The function of skin is that it enable us fell touch, pressure,pain,heat,etc.

The nose
The nose is an organ use to smell . human being has a poor sense of smell and it easily gets fatigued. The nose help us to perceive smell we particular smell when the brain receive impulse from a certain combination of smell chemoreceptors. remember our sense of smell is not as acute as that of dogs.in some animals smell chemoreceptors are located on the skin, antennae or other part of the body.

The tongue
The tongue is an organ use to taste the tongue is divided into taste buds taste buds lie in groove on the surface of the tongue.there are four basic taste.they are sour,sweet, salty, and bitter.all flavours are a combination of these taste.
Sweet and salty taste at the front,
Sour at the side and
Better at the back of the tongue

The eye
The eye is an organ of seeing it is found in all vertebrate.
Each eye is a spherical organ know as the eyeball. It is located in a bony socket in the skull . We blink automatically every two to ten seconds each eyeball is attached to the eye socket by six sets of muscles. The wall of the eyeball consists of there layers
The outermost sclera,
The middle choroid, and
The innermost retina
The eye perform two function which is image formation and accommodation.

The ear

Source
The ear is an organ of hearing and balance. The ear show how sound waves produced by a vibrating object reach the ear where they stimulate mechanoreceptors.these send impulse to the brain which interpret them enabling us to hear sound. Many terrestrial mammals use their sense of hearing widely to monitor their surrounding, particularly to detect sources of danger the ear is also sensitive to the position and movements of the body in space and so helps us to maintain our balance
The care of the ear are.

Don't use sharp or pointed objects for example biro or pencil while cleaning or scratching the ear.

The ear should be cleaned with cotton wool.

So we have to take care of the sense organ because it is very important to our body
