Back 16

reduced # of taste buds genetcially

Front 17

Insula

Back 17

interpretation of taste

Front 18

Where is the piriform cortex and what is it involved in?

Back 18

It is located on the inferior portion of the frontal lobe and is involved in the olfactory pathway

Front 19

Olfactory fibers from the hair cells of the nose pass through what structure before synapsing with the olfactory bulbs?

Back 19

Cribriform plate

Front 20

Where do the processes of the medial olfactory stria travel?

Back 20

Bilaterally to the piriform cortices and septal nuclei and ipsilaterally to the uncus, entorhinal cortex, ans amygdala.

Front 21

Where do the processes of the lateral olfactory stria travel?

Back 21

Ipsilaterally to the uncus and amygdala

Front 22

Which structures are involved with interpretation of odors (pleasant vs. noxious, etc)

Back 22

Piriform cortex, septal nuclei, and uncus.

Front 23

Which sturcutre is involved with olfactory memory?

Back 23

Front 24

What structure relays olfactory info from the hippocampus to the hypothalamus?

Back 24

The fornix

Front 25

What structure relays olfactory info from the amygdala to the hypothalamus?

Back 25

The stria terminalis

Front 26

What are the 3 types of cells in taste buds?

Back 26

sustentacular cells, receptor cells, and basal cells.

Front 27

Taste from anterior two-thirds of the tongue

Back 27

fibers travel in the chorda tympani of the facial nerve. Cell bodies are found in the geniculate ganglion of CN VII

Front 28

Taste from the posterior one-third of the tongue

Back 28

fibers travel in the glossopharyngeal nerve. Cell bodies are found in the inferior ganglion (petrosal ganglion) of IX

Front 29

Taste from the area adjacent to the epiglotis

Back 29

Fibers travel in the vagus nerve and cell bodies are found in the inferior ganglion of X

What is Argyll Robertson pupil?

Back 32

small pupils that constrict when objects are brought near to them but not as a response to increased light (neurosyphilis)
