Other senses

Question 1

Gustation (TASTE)

Answer 1

Taste is a chemical sense because a substance is what is detected (not just energy like in sight and hearing).

This is done through our taste buds.

Question 2

Gustation (TASTE)

Answer 2

Taste buds regenerate
approximately every two weeks.

“Supertasters” are individuals with
more papillae (therefore, more taste
buds) on their tongues.

Question 3

TASTEs

Answer 3

Traditional taste sensations consisted of 4 tastes…
Sweet
Sour
Salty
Bitter
Umami: An inherent savoriness. Described as brothy or meaty
Astringent: Puckers the mouth, numbs tongue, constricts throat – present in unripe bananas, pomegranates, cranberries, red meat, burnt/smoked food

Question 4

Olfaction (Smell)

Answer 4

Like taste, smell is a chemical sense. Odorants (molecules of the object you are smelling) enter the
nasal cavity to stimulate 5 million receptors to sense smell. The olfactory epithelium is responsible for detecting odorants, and is at the roof of the nasal cavity about 7cm above & behind the nostrils. Human can detect about 10,000 odors

Question 5

Olfaction (Smell)

Answer 5

1 = Olfactory bulb
2 = Mitral celss
3 = Bone
4 = Nasal epithelium
5 = Glumerulus
6 = Olfactory receptor cells

Olfactory receptors in the nasal
cavity regenerate approximately
once a month.

Question 6

Smell and Memory

Answer 6

Notice where the hippocampus is.

Where’s the olfactory bulb?

Nice and close to where memories are made

Question 7

Sensory Interaction

Answer 7

When one sense affects another sense, sensory interaction takes place.

The taste of fruit interacts with its smell and its texture on the tongue to produce the taste.
