2.
Are some taste preferences inborn?

Explanation

eg preference for sweet tastes for mother's milk and the aversion to bitter tastes for avoiding toxins. Experience can nevertheless modify taste preferences.

Submit
3. Does the body have the capacity to induce a preference for certain tastes due to deficiencies present?
Submit
4. Are the sensory cells in the taste bud efferent or afferent?

Explanation

These cells send the signal back to the CNS.

Submit
5. The anterior one third of the tongue is innervated by which cranial nerve?

Explanation

via chorda tympani

Submit
6. When the taste sense binds to a receptor the cell will
Submit
7. When a patient has anosmia, they have lost their sense of

Explanation

It is usually due to a disease of the olfactory nerves

Submit
8. The following are all examples of_______________:  i.e. taste, smell, carotid body receptors and osmoreceptors
Submit
9. The circumvallate papilla are found
Submit
10. Is smell directional or non-directional?
Submit
11. What cells are responsible for producing new olfactory receptor cells?
Submit
12. What receptors allow the body to ignore constant uninmportant information?

Explanation

With tonic receptors the parameters must constantly be monitored.

Submit
13. The primary gustatory area is near the sensory area for the

Explanation

It extends down into the insula. The insula is also part of the gustatory center.

Submit
14. New taste receptor cells differentiate from which types of cells?
Submit
15. Do olfactory neurons regenerate?

Explanation

They regenerate about every month.

Submit
16. The olfactory cell synapses with both the peri glomerular cell and _______ .

Explanation

The mitral cell will synapse with a granule cell

Submit
17. The olfactory nerves are
Submit
18. Are IP3 and cGMP involved in olfactory transdcution as well?
Submit
19. The posterior one third of the tongue is innervated by which cranial nerve?
Submit
20. Sustained stimulation will lead to ____________ .
Submit
21. What are the yellow colored cells?

Submit
22. What type of taste bud containing papillae are found at the most anterior part of the tongue, have one or more taste buds each and appear as cheryy red spots.
Submit
23. Which of the follwing basic tastes is associated with glutamate?
Submit
24. How many types of papillae on the tongue have taste buds?
Submit
25. The gland in this picture is known as the:-
Submit
26. Do the esophagus, larynx and pharynx have taste buds?

Explanation

as well as the soft palate.

Submit
27. The oropharynx and epiglottis are innervated by cranial nerve
Submit
28. Salt and sour taste senses are associated with:
Submit
29. What are the green colored cells? This section is from the nasal epithelium.
Submit
30. Which of the following either DO NOT adapt or adapt slowly?

Explanation

Phasic receptors adapt rapidly.

Submit
31. What are the medial, lateral and intermediate outcrops from the olfactory stalk known?

Explanation

At the tip of the stalk lies the olfactory bulb.

Submit
32. When considering how taste is perceived the taste stimuli interacts with channels or receptors that are located in the __________ .
Submit
33. Which receptors continually transmit signals for the duration of the stimulus?

Explanation

Phasic receptors will cease firing if the strength of a continuous stimulant remains constant

Submit
34. The first order neuron coming from the taste buds synapses on neurons located in the:-

Explanation

There are three neurons in the pathway before the signal arrives in the cortex.

Submit
35. Do all tastes result in increased calcium in the cell and subsequent release of the neurotransmiter?

Explanation

the fundamental system is the same for all the different types of taste. After calcium is released, calcium concentration increases, neurotransmitter is released and a signal is relayed to the CNS.

Submit
36. Taste receptors are clustered into organelles called
Submit
37. When the cell depolarizes in response to a taste receptor binding what second messenger is released?
Submit
38. The mitral cells send their signal to which stria?
Submit
39. Most revceptor/chanels are located on the _______________ which are located on receptor cells.
Submit
40. What is contained in a taste bud? check all that apply.
Submit
41. The primary center for olfaction is the ________ olfactory area.
Submit
42. Muscle stretch receptors and joint proprioreceptors are examples of tonic or phasic receptor types?

Explanation

This is because of the need to constantly update the CNS on the muscle length and joint position.

Submit
43. The pririform cortex and amydala and entorhinal areas are ______ that feed into the lateral olfactory area.

Explanation

These intergrate the signals coming into the lateral olfactory area and send them to the rest of the brain. They are located in the ancus.

Submit
44. What are the mechanisms of taste transduction? Check all that apply.
Submit
45. In a sensory pathway, what transduces the stimulus?
Submit
46. The third order neuronin olfaction will send axons up to where?
Submit
47. Taste receptor cells are continually replaced, every 10 to 14 days. Does this require any input from the sensory cells?
Submit
48. What papillae are found anterior to the fungiforms along the edge of the tongue and contain multiple taste buds?
Submit
49. Each taste bud contains: Check all that apply.
Submit
50. Taste and smell send messages to phylogenetically old areas of the brain that are associated with?  Check al that apply.
Submit
51. Which part of the olfactory system has the receptors for odorants?
Submit
52. In olfactory trasnduction, the G protein coupled receptors are related to
Submit
53. Are the receptor cells in the olfactory system derivatives of neuropeithelial cells?

Explanation

They are actual nerves in and of themselves.

Submit
54. What is the cortex where the perception of taste becomes conscious? Check al that apply.

Explanation

The insula is part of the primary gustatory complex.

Submit
