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

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'.

Multiple choice biology soldiers of defense human lymphatic system lymph and its function lymph and tissue fluid

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.

Spaces surrounding the trabeculae of spleen are composed of.

  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.

Cords of billroth are found in

  1. Liver

  2. Kidneys

  3. Spleen

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

The Cords of Billroth (also known as splenic cords or red pulp cords) are found in the red pulp of the spleen between the sinusoids, consisting of fibrils and connective tissue cells with a large population of monocytes and macrophages. These cords contain half of the human body's monocytes as a reserve so that after tissue injury these monocytes can move in and aid locally sourced monocytes in wound healing.

Squamous epithelium forms inner lining of which of the following?
I. Blood vessels
II. Lung alveoli
III. Salivary duct

  1. I and II only

  2. II and III only

  3. I, II and III only

  4. II and IV only
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Squamous epithelium is a thin, flat layer of cells ideal for diffusion. It forms the inner lining of blood vessels (endothelium) and the alveoli of the lungs, where gas exchange occurs.

Multiple choice zoology some common diseases diseases caused by protozoa protozoan disease protozoa: benefits and harmful effects

Other than intestine, Entamoeba histolytica often gets lodged in 

  1. Brain

  2. Liver

  3. Lungs and Testes

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Entamoeba histolytica is a microscopic endoparasite of man and is commonly found in the lumen of the upper part of the large intestine, that is the colon. In chronic cases, they get into blood circulation and migrate to the spleen, liver, lungs, gonads, and brain, where they produce secondary complications.

Thus, the correct answer is option D.
