Q
Taste bud
A
Sensory receptors in the bumps (papillae) on the tongue

Q
Process of tasting
A
- Taste buds detect specific molecule dissolved in the saliva
- Taste cells within taste buds detect molecules from one of the four basic tastes
- Impulses from taste bud are sent to the brain stem, the thalamus, then the gustatory area of the parietal lobe which is responsible for perception of taste.
9
Q
Olfactory Cells
A
Specific chemoreceptors, lining the upper nasal cavity.
10
Q
Process of smelling
A
- Particles bind to olfactory cells
- Ion channels in the cell membrane open, generating an action potential in the olfactory cells (directly linked to the olfactory bulb of the brain)
- Impulse is sent to emotional centres of the brain (limbic system) and the frontal lobe, where perception of odour occurs
