Week three review

Which chemical sense is responsible for smell?

• olfaction

• gustation

• tastants

• odorants

Where are odorants detected?

• olfactory bulbs

• The brain

• mucus membrane lining the roof of the nose

• I don't know

Which afferent facial nerve is responsible for transducing the front 2/3 of the taste buds?

• Cranial nerve VII

• vagus nerve

• ganglia

• cranial nerve X

what way does the olfactory and gustatory senses project?

• ipsilaterally

• centrally

• contralaterally

• anterolateral

Where are the majority of the taste buds located?

• inner cheek

• papillae

• volatile

• received by the hypothalamas

Filiform, fungiform, foliate, and Circumvallate belong to which chemical sense?

• tastants

• olfactory

• gustation

• glomeruli

What type of neuron carries the taste message back to the brainstem?

• unipolar

• biploar

• psuedo- unipolar

• pyrimidal

Answer explanation

These are considered psuedo-unipolar because the cell bodies of all the taste buds are found in a cluster called a ganglia in which the interneuronal tracts or dendrites project from different locations and are associated with different cranial nerves which are sent to the brain stem.

What cranial nerve is responsible for olfactory senses to be relayed through the cribiform plate?

• CN II

• CN XII

• CN VII

• CN I

Basket like assemblage of all the odor receptor input found in the olfactory bulb in the base of the frontal lobe is called..

• mitral cells

• glomerulus

• cribiform

• turbinals
