OUR 5 SENSES BY: BRITTANY HANEMAN, JAYLA CAVE, COLIN HAMMINGSON, JOHN SANTIAGO, MICK RUIZ, AND ISAIAH BLACK.
Facts • We have almost 10,000 taste buds in our mouth • Taste is the weakest of the five senses • Girls usually have more taste buds then boys • Your taste buds become less sensitive when you become older and older
FACTS • A single taste bud contains fifty to 100 taste cells representing all its taste sensations • A single taste cell seems to be restricted to expressing only a single type of receptors. • Humans receive taste through sensory organs called taste buds. • Everything would taste the same without taste buds.
TONGUE section • Bitterness: is a taste to many that is unpleasant it helps prevent ingestion of toxic substances • Saltiness: suppresses bitterness and is commonly added to chocolates, fruits, and deserts. • Sour: is the basic taste that is considered agreeable in small amounts it wards off ingestion of harmful substances • Sweetness: rewards the consumption of energy rich sugars • Umami: has a mild lasting aftertaste found in foods like cheese, soy sauce, tomatoes, grains, and beans
facts • Our skin acts as the protective barrier between our internal organs and the outside world. • Hot, Rough, Pain, Wet, and Sharp. These are just a few of the sensations that you can feel using your sense of touch. • The nerve endings in the body tell you if something is hot or cold. • The sense of touch is due to the very sensitive neurons that respond to any deformation of the plasma membrane.
EXAMPLES • Your sense of touch helps you to feel things in your environment. This can help you to understand unfamiliar objects. EX: It can let you know when something is wrong. • Your sense of touch also helps you to move and interact with your environment. EX: Your sense of touch allows you to pick up an egg with just enough pressure so that you won't drop it
EXAMPLES OWWW!! wow!!! Smooth as a babies bottom.
Parts of the eye Light moves in a straight line First into the cornea The lens then directs the ray into the retina • The retina is a tissue at the back of the eye that is sensitive to light energy • The retina has two types of cells: One are the rods which respond to dim light and detect shape and motion The second are the cones- they respond to bright light and colors
facts • Most people blink every 2-10 seconds • One in twelve males are color blind • A baby sees the world upside-down because its brain isn’t smart enough to turn the images right side up
GETTING THE AIR IN • When you inhale air through your nose, the air enters the nasal passages and travels into your nasal cavity. The air then passes down your throat into the trachea on its way to the lungs. • When you exhale the old air from your lungs, the nose is the main way for the air to leave your body. But your nose is more than a passageway for air. The nose also warms, moistens, and filters the air before it goes to the lungs.
HOW YOUR NOSE WORK • The nose is made of two large passages through which you inhale and exhale air. The septum which is composed of thin bone and cartilage, divides the passages before they lead into four sinus cavities. These sinus cavities are located above, behind, and below your eyes. Your nose helps you to breathe, smell, and taste.
HOW YOUR NOSE WORKS: • Air is filled with molecules, whose emissions make their way into your nose where they connect with, and attach to, cilia. Cilia are the little hairs that line your nasal passage. Their function is to trap unwanted particles, such as dust and dirt, and to assist with your sense of smell.
WHAT IS SOUND • Sound is a type of energy that is produced by vibrations. When am object vibrates it causes air partials to vibrate. These air partials bump into other air partials close by. This movement is called sound waves, they keep going till the energy runs out. So if your ear is within range of the sound waves you are able to hear the sound. • In dry air at 32°F or 0°C, sound travels 1,086 feet or 331 meters every second! That’s longer than a football field and it only takes a second!
INNER EAR • The inner ear is a delicate and complicated part of the ear, it includes the cochlea and vestibular, labyrinth. • The Cochlea is one of the most well known parts of the inner ear, contains different fluids that are able to tell incoming sounds as brain waves transfer them from the ear and the brain. If the fluids mix this can cause inner ear rupture. • The Vestibular transfers data about head position to the brain. A disturbance in this part of the ear may cause dizziness. This system affects posture and balance. • The Labyrinth is a group of canals that are filled with fluid. It connects different parts of the inner ear and carries signals produced by the cochlea and the vestibular system.
MIDDLE EAR • The middle ear is in between the eardrum and the inner ear. It contains three tiny bones called the hammer, anvil, and stirrup or stapes. They are named for their shapes. • Sound which is carried through the air makes the eardrum vibrate. The vibrations are transmitted across the middle ear space by the tiny ear bones. Movement of the stapes bone produces waves in the liquid-filled inner ear. • The middle ear chamber is connected to the back of the nose by a small canal called eustachian tube. This maintains equal pressure between the middle ear and the outside environment
OUTER EAR • The outer ear consists of the auricle, the part of the ear that you can see contain the ear lobe and external canal. They collect sound waves and carry them toward the ear drum. • The main job of the outer ear is to collect sounds, whether they're your friend's whispers or a barking dog.
