The Organs of Sense

        The sense organs are the body organs by which humans are able to see, smell, hear, taste, and touch or feel. The five sense organs are the eyes (for seeing), nose (for smelling), ears (for hearing), tongue (for tasting), and skin (for touching or feeling).

About Five Sense Organs

Eyes (Sense of Sight/See)

1. Sight, also referred to as vision, is our ability to see.
2. Eyes are the visual sensory organs of the human body.
3. Human eyes vary in color depending on the amount of melanin in the body.
4. Our eyes are sensitive to images of light.
5. Blindness is the inability to see and he scientific study of sight is called optics.
   

Nose (Sense of Smell)

1. The sense of smell is also referred to as olfaction.
2. We have our olfactory system by which we smell and perceive different odors and scents. The nose can also be an organ to aid in our sense of taste.
3. Humans breathe through two holes called nostrils.
4. There are hundreds of olfactory receptors that interpret the smells around us.
5. Anosmia is the inability to smell.

Ears (Sense of Hear)

1. Hearing, also referred to as auditory perception or audition, is our ability to perceive sounds.
2. We have our auditory system by which we detect vibrations and hear sounds.
3. Vibrations are transmitted through a medium such as air. These vibrations are mechanically carried on from the eardrum through the tiny bones named the malleus, incus, and stapes.
4. Humans may experience hearing loss when the ability to hear is lost partially or completely.
5. Deafness is the inability to hear.

Tongue (Sense of Taste)

1. We have one tongue by which we perceive various tastes and flavors like sweet, salty, sour, and bitter.
2. The small bumps on the tongue are the papillae.
3. In between the papillae are the taste buds. Taste buds, also called gustatory calyculi, are the sensory organs on the tongue’s upper surface.
4. The different parts of the tongue detect distinct flavors: front for salty and sweet, back for bitter, and sides for sour.
5. Ageusia is the inability to taste.

Skin (Sense of Touch)

1. Our skin is the largest organ as it covers our whole body.
2. The receptors on our skin allow us to perceive texture, pain, temperature, pressure, and pain.
3. Touch is also referred to as tactician, somatosensation, or mechanoreception.
4. The sense of touch is activated by neural receptors found in the skin, and other surfaces like the tongue and hair follicles.
5. Tactile anesthesia is the inability to feel anything physically.
