Fungiform

Question 21

Leaf-like; lateral
margins; most taste buds
degenerate in early
childhood

Answer 21

Foltate

Question 22

thread-like structures contains tactile receptors but no taste buds(mastication or chewing)

Answer 22

Filiform

Question 23

Gastatory pathway:1st

Answer 23

Taste Receptors: Taste buds on the tongue contain taste receptor cells

Question 24

Gastatory pathway:2nd

Answer 24

Cranial Nerves: Sensory neurons from the taste buds transmit signals to the brain via cranial nerves VII (facial), IX (glossopharyngeal), and X (vagus).

Question 25

Gastatory pathway:3rd

Answer 25

Brainstem: The signals reach the nucleus of the solitary tract in the medulla oblongata.

Question 26

Gastatory pathway:4th

Answer 26

Thalamus: From the medulla, the signals are relayed to the ventral posterior medial nucleus of the thalamus.

Question 27

Gastatory pathway:5th

Answer 27

Gustatory Cortex: The thalamus sends the signals to the gustatory cortex in the cerebral cortex, where taste is perceived and interpreted.
