Gustatory Receptors (Remember using GT almost like GTA where G is for gustatory and T for taste)

Fungiform papillae, Circumvallate papillae and Foliate papillae
(just remember it's fungi, circle and foil)

small, on entire surface of tongue (remember using: fugi = mushroom and they are small and everywhere)

Inverted “v” near back of tongue (Remember using: It has V in it indicating it is V shape)

Located in the the corners of tongue (think of foil wrap, they are around the food, so foliate is in the corners)

- Sweet
- Salty
- Umami (savory)
- Sour
- Bitter
(Remember using BUSSS, (yes it has 3 s))

Substances dissolved in saliva enter the taste pore

Substances become attached to chemoreceptor molecules on the cell membrane

There is a change in membrane permeability

There is depolarization of the taste cells

The information is sent via the facial and glossopharyngeal nerves to the brainstem, thalamus, and gustatory cortex in the cerebral cortex at the frontal and temporal lobes.

Odorant binding to G protein (smell = odor so it's odorant)

An odor-producing molecule becomes bound to a receptor

The cilia of the olfactory neurons depolarize

Action potentials are initiated in the olfactory neurons

The signal is sent to the olfactory tract via the olfactory bulb

The nerve fibers of the olfactory tract take the information to the olfactory cortex in the temporal lobe of the brain.
