SMELL
After detecting an odor, the receptor cells send a signal through this nerve directly to the brain.
Olfactory nerve
This muscular organ in the mouth contains the taste buds and moves food around to mix it with saliva.
TONGUE
The skin has two main layers: the outermost layer is the epidermis and the inner layer is this one.
dermis
People who suffer from anosmia (the total loss of the sense of smell) often complain that they have also lost most of this other sense, even though their taste buds still function.
TASTE
A common and temporary medical condition, such as a cold or the flu, that can cause a temporary loss of taste and smell.
flu/cold
These are the two external openings of the nose through which air and odor molecules enter the nasal cavity.
NOSTRIL
These small bumps on the surface of the tongue contain the structures that allow us to taste food.
PAPILLAS
This organ, the largest in the human body, contains specialized touch receptors.
SKIN
If you could only use your sense of taste, and not your sense of smell, you could only say this about a cup of black coffee.
bitter
A serious skin injury, caused by heat, that damages touch receptors and requires immediate medical attention.
BURN
This moist mucus inside the nasal cavity helps to trap odor molecules before they reach the receptors.
MUCUS
These small bumps on the surface of the tongue contain the structures that allow us to taste food.
taste buds
Name three different things that the sense of touch allows us to feel, besides pressure.
temperature, pain, texture, or vibration
This type of receptor, found in the skin, detects temperature changes, telling you if something is hot or cold.
thermoreceptor
A simple and common way to take care of your sense of smell and prevent irritation caused by harsh chemicals.
wear a mask
The name of the specialized cells that have tiny hairs (cilia) to capture odor molecules and convert the chemical signal into an electrical message.
The ability to detect this taste, often associated with salty foods like cheese or meat broth, was added as the fifth basic taste.
umami
This concept explains why you can feel the light touch of a feather on your arm, but barely notice the constant pressure of your clothes.
SENSORY ADAPTATION
The total number of specialized cells on the tongue that detect taste, which can regenerate every 10 to 14 days.
taste buds (10,000)
A good habit for the senses of taste and touch in the mouth is to avoid eating or drinking things that are extremely...
spicy (or hot)
This part of the brain is the first stop for olfactory signals, located just above the nasal cavity, and organizes the signals before sending them to the cerebral cortex.
OLFACTORY BULB
Name the five main types of tastes that the human tongue can detect.
sweet, sour, salty, bitter and umami
These small structures are found in the dermis, the outermost layer of the skin, and help regulate body temperature by releasing a salty liquid onto the skin's surface.
Sweat glands
Name the three layers of the skin, from the outermost to the innermost.
Epidermis, dermis and hypodermis.
Name one habit that helps protect the tongue from harmful bacteria and acids, ensuring that the taste buds remain healthy.
