Senses Review

Taste buds are located inside raised bumps on the tongue called ________.

Match the following types of tongue papillae to their shape and location:

Groups:

(a) Fungiform

,

(b) Foliate

,

(c) Circumvallate

,

(d) Filiform

• located at back of tongue

• located on entire surface of tongue

• located at front of tongue

• mushroom-shaped

• flat-shaped

• dome-shaped

• cone-shaped

• located on sides of tongue

Which of the following tongue papillae are involved with the sense of taste? (select 3)

• fungiform

• foliate

• cicumvallate

• filiform

Put the steps of tasting in order:

• Food molecules are dissolved by saliva

• Dissolved food molecules enter the tongue papillae and reach the taste buds

• Food molecules bind to receptors on the gustatory cell hairs

• Activated cells form nerve impulses carried by facial nerves

• Gustatory cortex receives nerve impulses and interprets the pattern as taste

The gustatory sense involves which of the following tastes? (select all that apply)

• Sweet

• Sour

• Salty

• Bitter

• Umami

Odor molecules enter through the ​nasal (a)   where particles are filtered out. They pass through a large chamber behind the nose called the nasal​ (b)   . The cavity acts to warm and humidify air before it passes into the ​ (c)   .

• vestibule
• cavity
• lungs

Odor molecules travel to the roof of the ​ (a)   to a region called the ​ (b)   . This structure features millions of sensory receptors called ​ (c)   . The molecules then bind to receptors found on ​ (d)   . The activated sensory receptors generate ​ (e)   .

• olfactory epithelium
• nasal cavity
• olfactory neurons
• olfactory cilia
• nerve impulses

​ (a)   , caused by odor molecules activating sensory receptors, travel along axons to a small region called the ​ (b)   . The bulb relays the stimulus along the ​ (c)   , which travels to the ​ (d)   . A brain region called the ​ (e)   interprets the nerve impulses as smell.

• olfactory bulb
• olfactory nerve
• brain
• olfactory cortex
• Action potentials

Which of the following is the best definition for combinational diversity in the olfactory sense.

• The olfactory system's ability to detect thousands of smells because each odorant molecule binds with multiple olfactory neurons

• The olfactory system's ability to detect taste through smell because odorant molecules bind to a single neuron

• The olfactory system's ability to detect odors based on color
• The olfactory system's ability to detect only pleasant odors
