Introduction:
Gustatory cells are the specific receptor cells, which respond to the chemicals that are dissolved in the saliva present in taste buds of the tongue. The hairs or the microvilli of these cells project through the taste pore and gets depolarized on stimulation. The impulses are then transmitted to the brain.
Answer to Problem 1MC
Correct answer:
Gustatory cells are the epithelial cells.
Explanation of Solution
Explanation for the correct answer:
Option (d) mentions that gustatory cells are the epithelial cells. The specific taste receptor cells, which respond to the chemicals dissolved in the saliva, are the gustatory cells. These are epithelial cells of body present in the skin, blood vessels, urinary tract, or organs. Hence, option (d) is correct.
Explanation for incorrect answers:
Option (a) mentions that gustatory cells are the bipolar neurons. Gustatory cells are the specific taste receptor cells, while the bipolar neurons are found in the olfactory system and the eye’s retina. So, it is an incorrect option.
Option (b) mentions that gustatory cells are the multipolar neurons. Gustatory cells are the specific taste receptor cells, while the multipolar neurons are found in the brain and spinal cord. So, it is an incorrect option.
Option (c) mentions that gustatory cells are the unipolar cells. The unipolar cells transduce the stimulus related to sound, light and temperature. Whereas, the gustatory cells are the taste receptor cells. So, it is an incorrect option.
Hence, options (a), (b), and (c) are incorrect.
The gustatory cells are the specific taste receptor epithelial cells that responds to the chemicals, which are dissolved in the saliva.

- The eye doctor uses an Acetylcholine-receptor blocker to maximally dilate the pupils; this allows the doctor to peer deep into the posterior eye-ball and observe the retina. Considering these facts, which nervous system is usually controlling the pupil diameter? (Which nervous system is “Acetylcholinergic"?) a. Somatosensory nervous system b. Sympathetic nervous system c. Reticular attenuating nervous system d. Parasympathetic nervous systemarrow_forwardSelect the statement that best describes the organization of the somatosensory cortex. a. A distorted neural representation of the body space is due to differences in the number of neurons that code high- and low-resolution areas. b. None of the answers. c. The body area is represented by a single map in the primary somatosensory cortex (S1). d. A secondary somatosensory cortex is unnecessary since all somatosensory information is processed in the primary somatosensory cortex (S1). e. A proportional neural representation for each region of the body yields a realistic map of body space.arrow_forwardDescribe the passage of information through the nervous system using a specific example. Be sure to include in detail: A. The collection of stimuli at the sense organ and receptors involved as well as graded potential. B. The passing of the impulse along ascending pathways C.

- What does the neuron composition of the dorsal root ganglion tell you about sensory coding in the somatosensory system? a. The large axon sizes have a slower conduction velocity than small axon sizes. b. The uniform axon sizes for all neurons indicate that they have the same conduction velocity. c. Multiple modalities or sensations can be detected from the skin. d. Only a single modality or sensation can be detected from the skin. e. Processing must occur directly in the skin since the neurons in the dorsal root ganglion are second order neurons.arrow_forwardLidocaine is an anesthetic that is used to prevent the propagation of action potentials.
