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

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'.

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'.

Bitter taste is perceived by buds present on the tongue at.

  1. Posterior part

  2. Tip

  3. Lateral side

  4. Ventral side
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Bitter taste receptors are concentrated at the posterior part (back) of the tongue. This is thought to be an evolutionary mechanism to trigger a gag reflex for potentially toxic substances.

Which of the following is an incorrect match? 

  1. Filiform papillae: Smallest and most numerous, found mainly in the centre of tongue

  2. Fungiform papillae: Most numerous, near the base of tongue

  3. Foliate papillae: Not developed in the adult human tongue

  4. Vallate papillae: Largest papillae , each surrounded by a circular groove
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In tongue, small structures called papillae are present. They are mainly of four types- filiform papillae, fungiform papillae, foliate papillae, circumvallate papillae. Most of them are associated with taste buds. The filiform papillae are the smallest amongst the four and are most numerous. They are scattered throughout the dorsal surface of the tongue and not just at the center of the tongue.

So, the correct answer is 'Filiform papillae: Smallest and most numerous, found mainly in the centre of tongue'.

All of the following organs in the human body are located both on the right and the left sides, except

  1. Spleen

  2. Kidneys

  3. Lungs

  4. Eyes
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The spleen is the largest organ in the lymphatic system. It is an important organ for keeping bodily fluids balanced, but it is possible to live without it. The spleen is located under the ribcage and above the stomach in the left upper quadrant of the abdomen. So, the correct option is "A" (Spleen).

Arzygrophillic fibers are present in

  1. In spleen

  2. In tendons

  3. In ligament

  4. In bloood vessel
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Reticular fibers (type III collagen) are thin collagen fibers not typically detected with routine H & E staining. However, these fibers stain black with silver stain and are often called argyrophilic fibers. The spleen demonstrates the supportive network of reticular fibers present in many organs. In this slide, the delicate reticular fibers are black and the thick collagen fibers are red/brown.

So, the correct option is 'In spleen'.

The tissue which forms the basic structure of lymphoid organs, spleen etc., is

  1. Lymphoid tissue

  2. Cartilage tissue

  3. Elastic tissue

  4. Areolar tissue
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The tissue, which forms the basic structure of lymphoid organs, spleen etc., is lymphoid tissue. Cells and organs that make up the lymphatic system, such as white blood cells (leukocytes), bone marrow, and the thymus, spleen, and lymph nodes. Lymphoid tissue has several different structural organizations related to its particular function in the immune response. The most highly organized lymphoid tissues are in the thymus and lymph nodes, which are well-defined encapsulated organs with easily identifiable architectures. In the spleen, the lymphoid tissue is a cylinder of loosely organized cells surrounding small arteries.

When there is a sudden loss of blood from the body, the organ which supplies blood is?

  1. Spleen

  2. Heart

  3. Liver

  4. Lung
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The spleen is the largest lymphatic organ in the body and is positioned in the superior abdomen. The spleen plays important roles in regard to red blood cells and the immune system. It removes old red blood cells and holds a reserve of blood, which can be valuable in case of hemorrhagic shock, blood loss and also recycles iron. It purifies the blood and helps the immune system to recognize and attack foreign antibodies and disease. The spleen is composed of the red and white pulp. The white pulp produces and grows immune cell as well as blood cells. On the other hand, the red pulp is responsible for purifying the blood and removing dead or old blood cells.

  1. White pulp

  2. Red pulp

  3. White pulp and red pulp

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

The spleen contains white pulp (lymphoid tissue) and red pulp (vascular tissue). The trabeculae provide structural support, and the spaces between them are occupied by these two types of pulp.
