The squamous epithelium is mainly involved in

  1. Protection

  2. Absorption

  3. Secretion

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Squamous epithelium is a type of epithelium tissue. The cells of this tissue are thin, flat and closely packed. These are found in cavities of mouth, oesophagus, alveoli and blood vessels. This tissue gives protection against mechanical injury and also blocks the entry of pathogens or germs. 

So, the correct option is 'Protection'.

Multiple choice evs science of kitchen sense of touch, smell and taste types of taste components and importance of food

On which part of the tongue, most of the taste get detected?

  1. Front

  2. Back

  3. Left

  4. Right
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • The upper surface of the tongue has small projections called papillae, some of which bear taste buds.
  • About 50 -150 taste cells are found in a taste bud. These cells detect all 4 tastes i.e sweet, sour, salty and bitter.
  • The taste buds for "sweet" are on the tip of the tongue; the "salt" taste buds are on either side of the front of the tongue; "sour" taste buds are behind this; and "bitter" taste buds are way in the back.
  • Most of the taste gets detected in the front part of the tongue because most of the taste buds are present in the front region of the tongue.
  • So, the correct answer is 'Front'.

The upper surface of tongue is called as

  1. Papillae

  2. Lingual septum

  3. Dorsum

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

The tongue is a muscular structure which is present in the oral cavity. The upper surface of the tongue is called as the dorsum. There are papillae on the dorsum. These are raised and elevated structures on the upper region of the tongue. There are several taste receptors on the papillae. The taste receptors help in detection of taste. 

Thus, the correct answer is option C.

Salty taste is perceived by the taste buds located on 

  1. Tip of the tongue

  2. Sides of the tongue

  3. Back side of the tongue

  4. Both A and B
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The four basic kinds of tastes are: sweet, salty, sour and bitter. The salty/sweet taste buds are located near the front of the tongue, the sour taste buds line the sides of the tongue, and the bitter taste buds are found at the back of the tongue. The center of the tongue has few taste buds. 

Thus, the correct answer is option A.

Which of the following act as a receptor on the tongue to taste?

  1. Taste buds

  2. Salivary gland

  3. Sensation

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
The tongue is composed of voluntary muscle. The superior surface consists of stratified squamous epithelium, with numerous papillae. These are taste buds. Taste buds contain sensory receptors called taste receptors for the sense of taste. They contain chemoreceptors which are sensitive and are by very small amounts of chemicals that enter the pores dissolved in saliva. So, the answer is B.

Multiple choice biology for the continuity of generation reproductive systems different stages of growth reproductive system in humans

Spot the odd one out from the following structures with reference to the male reproductive system.

  1. Rete testis

  2. Epididymis

  3. Vasa efferentia

  4. Isthmus
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Females have two oviducts (or Fallopian tubes). Each oviduct has three regions, infundibulum, ampulla and isthmus. Isthmus is the narrow part closest to uterus, while infundibulum is the first part of oviduct that is encountered by released ova.

Given below are the three statements each with two blanks. Select the option which correctly fills up the blank in any two statements. (A) Each seminiferous tubule is lined on Its inside by two types of cells called (i) and (ii) .
(B) The seminiferous tubules open into the  (i)  through  (ii).
(C) The enlarged end of penis called the   (i)   is covered by a loose fold of skin called the   (ii)  

  1. (A)-(i)spermatogonia, (ii) follicular cells

    (B)-(i) vas deferens, (ii) urethral meatus

  2. (B)-(i) vasa efferentia, (ii) rete testis

    (C)-(i) glans penis, (ii) foreskin

  3. (A)-(i) spermatogonia, (ii) Sertoli cells

    (C)-(i) urethral meatus, (ii) scrotum

  4. (A)-(i) spermatocytes, (ii) oogonia

    (B)-(i) rete testis, (ii) vasa efferentia
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The seminiferous tubule is present in the testicular lobule and is highly coiled and produces sperms. The seminiferous tubule opens into the vasa efferentia (small ducts) through the rete testis (a network of interconnecting tubules where the straight seminiferous tubules empty). The enlarged part of the penis or the male genitalia is called the glans penis or head of the penis (sensitive bulbous structure at the distal end of the human penis) and is covered by a foreskin (prepuce) a double-layered fold of smooth muscle tissue, blood vessels etc, to protect the glans penis and urinary meatus. 

So, the correct option  is, (B)-(i) vasa efferentia, (ii) rete testis (C)-(i) glans penis, (ii) foreskin.
