5 facts about sense of smell
1 You can smell as fresh as a daisy every month and your scent cells are renewed every 28 days, so every four weeks you get a new “nose”.
2 Smell is the most sensitive of the senses. People can remember smells with 65% accuracy after a year, while visual recall is about 50% after three months.
Research has shown that smell is the sense most linked to our emotional recollection. So, when linked to a product, that can reap dividends.
Studies show that 75% of emotions are triggered by smell which is linked to pleasure, well-being, emotion and memory – handy when you want people to buy your products.
One of the most evocative smells from childhood is crayons.
A survey found that 85% of all people remembered their childhood when they caught the smell of Crayola crayons and the newer crayon-scented coloured pens.
3 The sense of smell gets bored easily. When entering a bakery or florist you are very aware of the aroma but by the time you reach the check-out you will no longer be able to smell the different aromas around you.
4 The sense of smell is the first of all our senses to develop. Even before we are born, our sense of smell is fully formed and functioning.
5 A woman’s sense of smell is much stronger than a man’s. It is heightened even more in the first half of the menstrual cycle and reaches its peak when she is most fertile.
5 facts about sense of hearing
1.The malleus, incus and stapes (otherwise known as the hammer, anvil and stirrup) are the smallest bones in the human body and are full size at birth. All three together could fit on a penny.

3.The cochlea (inner ear) is about the size of a pencil eraser.

4.The ear never stops working, even when people are asleep. The ear continues to hear sounds, but the brain shuts them out.

5.Ears are self-cleaning. Pores in the ear canal produce cerumen, or ear wax, and tiny hairs, called

    However, while the effects of these scents in the form of aromatherapy and essential oil candles have not been scientifically proven, there is a lot of evidence to suggest otherwise. Use of certain scents is said to have an effect directly on the human brain, by entering the body through scent receptors in the nose and mouth and then affecting the limbic system of the brain. They also can have a psychological effect. If a person always uses certain scented essential oil candles when they are relaxed in a bath, they will gradually associate that scent with a sensation of calm and relaxation. From that point onwards, it will induce the feeling of relaxation…

    A major breakthrough in understanding our sense of smell occurred in 1991 when Richard Axel and Linda Buck discovered the large family of genes that give us our sense of smell. (143) They discovered that there are a huge number of genes dedicated to olfactory sense. They also discovered that only three percent of our entire genome is dedicated to genes for detecting and processing different odors. For this discovery, Axel and Buck received and shared the Nobel Prize in 2004. (144)…

    The medical term for when an individual suffers a loss of their sense of smell is called anosmia. Anosmia can be caused by a nasal condition, brain injury, or in some rare circumstances a person can be born without a sense of smell which is referred to as congenital anosmia.

    Auditory System

    • 618 Words
    • 3 Pages

    To begin, energy from the environment stimulates the receptor cells in whichever sense organ is being used. If this information were auditory, the ear would convert sound waves in the air into electrical impulses that would further be interpreted by the brain as sound. A sound wave first enters the pinna, the fleshy part of the ear on the outside of the body. It then travels through the external auditory canal where it then meets the eardrum, a thin membrane in the outer ear. The eardrum then vibrates in response to the sound wave. What we hear will depend on the wavelength and frequency of the wave. The eardrum is connected to a group of three small bones call “the ossicles” in the middle ear. This group includes the malleus, incus and the stapes. These three bones, the smallest in the human body, protect the eardrum from more intense sounds and also deliver the vibrations to the base of the stapes. The stapes then sends the vibrations into the inner ear and interacts with the round window. The round window, a small membrane that allows liquid inside the inner ear to be displaced and receive the vibration. The vibration travels through the spiral structure of the inner ear called the cochlea and ends at the round window.…

    When the olfactory receptors located on the cilia are stimulated by chemicals dissolved in the mucus, they transmit impulses along the olfactory filaments, which comprise the olfactory nerve; this nerve conducts the impulses o the olfactory cortex of the brain. An "odor snapshot" is made in the olfactory cortex, which then becomes part of our long-term memory. The olfactory pathways are closely tied to the limbic system, the emotional-visceral part of the brain. Odors elicit strong emotional responses.…
