21
Q

chemoreceptors in structures called blank in taste

A

taste buds

22
Q

taste buds on superior surface of tongue in blank

A

papillae

23
Q

epithelial projections where taste buds lie

A

papillae

24

gustatory pathway uses cranial nerves blank blank and blank

A

VII, IX, X

29
Q

gustatory pathway has blank fibers that synapse with blank in medulla

A

afferent, nucleus solitarius

30
Q

gustatory pathway goes to blank and blank

there are also blank in the external acoustic meatus

A

37
Q

two functions of external ear

A

protect middle/inner ear, limit microorganism growth, funnel vibrations, deny access to foreign objects
