Olfaction _ the thalamus as its first relay.

bypasses

New cards

Taste receptor cells are _ that use different transduction mechanisms for different taste categories.

non-neuronal sensory cells

3
New cards

Five taste categories:

Salt, sour/acid, sweet, bitter, and umami. Umami is associated with glutamate.

4
New cards

Taste buds contain _.

support cells and type 2 receptor cells

5
New cards

The receptor cells are _; they release _ onto _.

not neurons, ATP or serotonin, primary sensory neurons

6
New cards

ACh is _.

not a secondary messenger, it is a signaling molecule that binds to a recpetor.

7
New cards

How does Sweet, bitter, and umami flavors get tasted?

ligand binds to GPCR, gustductin transducers signal, Ca2+ gets released from ER, Na+ enters cell, ATP is released onto sensory neuron

8
New cards

How does sour get tasted>

H+ enters or affects the receptor cell and closes K+ channels, depolarizing the cell. Voltage-dependent Ca2+ entry then supports serotonin exocytosis onto the primary sensory neuron.
