Multiple choice biology windows of knowledge human tongue organ of taste tongue : the organ of taste

Each taste bud has a cavity with a pore called as the

  1. Gustatory pore

  2. Taste pore

  3. Papilla pore

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Papillae give the tongue its rough texture. The surface of the papillae is covered by thousands of taste buds.
Taste buds have the taste sensors or the taste receptors inside them.
Each taste bud has a cavity with a pore called as the taste pore.
Inside each cavity is taste receptor cells or gustatory receptor cells, bathed in saliva.
Each receptor cell has a free hair-like cilium also called as the taste hair which projects into the outer taste pore.
Additionally, each receptor cell has a nerve fibre called as the gustatory nerve extending from its base to the taste centre of the brain.

Which of the papillae are not found in human?

  1. Fungiform papillae

  2. Circumvallate papillae

  3. Foliate papillae

  4. None of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Humans possess fungiform, circumvallate, and foliate papillae. Since all these are found in humans, the statement that none of the above are missing is technically true, or the question is flawed.

Which of the following separates the two parts of the tongue?

  1. Papillae

  2. Lingual septum

  3. Terminal sulcus

  4. Lingual sulcus
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

  • Terminal sulcus of the tongue is a V-shaped groove, with a posteriorly oriented apex, on the surface of the tongue, marking the separation between the anterior (oral or horizontal) and the posterior (pharyngeal or vertical) parts of the tongue. Hence, Terminal sulcus separates the two parts of the tongue.
So, the correct answer is 'Terminal sulcus'.

Which of the following is the supporting cell for taste receptor?

  1. Cuboidal cells

  2. Columnar cells

  3. Ciliated cells

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The taste buds are comprised of two main type of cells, receptor cell and the supporting cell. The receptor cells are neurosensory. They have one free end and the other nerve ending travelling to the taste area of the brain. The supporting cells are the columnar cells. These cells are present between the receptor cells. These cells are about 40 in number. 

Thus, the correct answer is option B.

Which of the following states the location of taste buds on the tongue?

  1. Pouches

  2. Papillae

  3. Palate

  4. Pupillae
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

  • Lingual papillae (singular papilla) are the small, nipple-like structures on the upper surface of the tongue that give it its characteristic rough texture.
  •  The four types of papillae on the human tongue have different structures and are accordingly classified as circumvallate (or vallate), fungiform, filiform, and foliate. All except the filiform papillae are associated with taste buds. Hence, Papillae states the location of taste buds on the tongue.
 So, the correct answer is 'Papillae'.

Fungiform papillae carry which of the following cranial nerve?

  1. VII

  2. IX

  3. X

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Fungiform papillae contain taste buds (especially for bitter taste), temperature receptors and have a good blood supply. They are scattered over the top and sides of the tongue, mainly towards the tip.
  • Cranial nerves are the nerves which arise from the brain and spinal cord. The facial nerve is the 7th cranial nerve it arises from the pons of the brain stem.
  • The fungiform papillae are innervated by the VII cranial nerve. Hence through 7th cranial nerve fungiform papillae send sensory signals of taste to the brain stem.
  • So, the correct answer is 'VII'.

The cranial nerve that carries information of taste from epiglottis is

  1. VII

  2. IX

  3. X

  4. VIII
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The taste receptor cells send information detected by clusters of various receptors and ion channels to the gustatory areas of the brain via the seventh, ninth and tenth cranial nerves. The X nerve or vagus nerve carries information from the back of the oral cavity and the epiglottis.

So, the correct answer is option C.

Surface for attachment of tongue is

  1. Palatine

  2. Sphenoid

  3. Pterygoid

  4. Hyoid apparatus
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • A single U-shaped bone which is present at the base of the buccal cavity is called as Hyoid. Hyoid bone occurs in the skull.
  • The hyoid bone is also called and lingual or tongue bone. The term hyoid apparatus refers to the bones of the tongue.
  • The primary function of the hyoid bone is to serve as an anchoring structure for the tongue. Hence surface for attachment of tongue is Hyoid apparatus.
  • So, the correct answer is 'Hyoid apparatus'.

Taste buds are located on

  1. Palate

  2. Tongue only

  3. Pharynx

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
A. Palate is the roof of mouth that separates the cavity of mouth from the nose.
B. Tongue is a muscular and movable organ which is attached to the floor of mouth.
C. Pharynx is the part of alimentary canal that connects nose and mouth to the oesophagus.
Taste buds or receptors sense the salty, sour, sweet and bitter taste and are located on palate, tongue, pharynx, upper oesophagus and cheeks.
Hence, all the options are correct.
So, the correct answer is 'All of the above'.

  4. Receptors in skin
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
A. Rod cells of eye are photoreceptors which are associated with vision under low light.
B. Cone cells of eye are photoreceptors which are associated with daylight vision and colour vision.
C. Taste buds of tongue are gustatoreceptors that sense different tastes.
D. Receptors in skin are tangoreceptors that sense touch.
So, the correct answer is 'Taste buds of tongue'.
