Multiple choice biology breathing and respiration regulation of breathing human respiratory system contro and disorders of respiration

Larynx is a modified portion of

  1. Pharynx

  2. Trachea

  3. Bronchus

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

Larynx (voice box) is located between the pharynx and the trachea. It is the upper modified part of trachea and leads to trachea or windpipe. It has a framework of cartilage that protrudes in the front of the neck and sometimes is referred as the Adams apple. The larynx is considerably larger in males than in females; hence, the Adams apple is much more prominent in males. At the upper end of the larynx, vocal cords are present which help in production of speech. They are set into vibration by the flow of air from the lungs. A difference in the size of the larynx is what accounts for the difference between male and female voices; because male larynx is larger than a female larynx, usually male voice is lower in pitch. The nasal cavities, the sinuses, and the pharynx all serve as resonating chambers for speech, just as the cabinet does for a stereo speaker.

In humans, sound is produced by

  1. Syrinx

  2. Larynx

  3. Bronchus

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

In humans, the larynx is called the voice box. The larynx (voice box) is located between the pharynx and the trachea. It has a framework of cartilage, that protrudes in the front of the neck and sometimes is referred to as Adam's apple. The larynx is considerably larger in the male than in the female; hence, Adam's apple is much more prominent in the male. At the upper end of the larynx are the vocal cords, which serve in the production of speech. They are set into vibration by the flow of air from the lungs.

In humans, the larynx (voice box) is located between the pharynx and the trachea. It has a framework of cartilage that protrudes in the front of the neck and sometimes is referred to as the Adam's apple. The larynx is considerably larger in the male than in the female. Hence, the Adam's apple is much more prominent in the male. At the upper end of the larynx are the vocal cords, which serve in the production of speech. They are set into vibration by the flow of air from the lungs. A difference in the size of the larynx is what accounts for the difference between the male and female voices; because a man's larynx is larger than a womans, his voice is lower in pitch.

So, the correct answer is 'Larynx'

Adam's apple represents

  1. Arytenoid cartilage of larynx

  2. Cricoid cartilage of larynx

  3. Thyroid cartilage of larynx

C Correct answer
Explanation

The larynx (voice box) is located between the pharynx and the trachea. It has a framework of cartilage that protrudes in the front of the neck and sometimes is referred to as the Adam's apple. The larynx is considerably larger in the male than in the female; hence, the Adam's apple is much more prominent in the male. In human males ventral surface of thyroid cartilage make up the Adam's apple.

9 cartilages among them 3 are paired and 3 are unpaired occurs in

  1. Pharynx

  2. Larynx

  3. Glottis

  4. Bronchial tube
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • The larynx (voice box) is a cartilaginous box which helps in sound production.
  • It consists of 9 cartilages among them 3 are paired and 3 are unpaired.
  • Vocal cords are composed of twin infoldings of mucous membrane stretched horizontally across the larynx. They vibrate, modulating the flow of air being expelled from the lungs during phonation.
  • Hence vocal cords occur in Larynx.
  • So, the correct answer is 'Larynx'.

Arytenoid cartilage occurs in

  1. Larynx

  2. Nose

  3. Hyoid

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

The arytenoid cartilages are a pair of small cartilages, shaped roughly like three-sided pyramids, which are located toward the rear of the larynx and play a vital role in positioning and adjusting the vocal folds during speech.

So, the correct option is is 'Larynx'.

Two fibro-elastic strands of larynx extend between.

  1. Thyroid and cricoid

  2. Thyroid and arytenoid cartilages

  3. Cricoid and tracheal cartilaginous ring

  4. Santorini and thyroid cartilages
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The vocal cords (vocal folds) are two fibro-elastic bands located within the larynx. They stretch between the thyroid cartilage anteriorly and the arytenoid cartilages posteriorly.

_____ projects obliquely upwards behind the tongue and the hyoid bone, pointing dorsally.

  1. Epiglottis

  2. Glottis

  3. Larynx

  4. Pharynx
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
    • The epiglottis is a large, leaf-shaped piece of cartilage lying on top of the larynx. It projects obliquely upwards behind the tongue and the hyoid bone, pointing dorsally.
    • During swallowing of food the larynx elevates, causing the epiglottis to fall on the glottis (opening into larynx) like a lid, closing it off, this prevents food from entering the windpipe (trachea). Hence The structure which prevents the entry of food particles into the respiratory passage is Epiglottis.
    • So, the correct answer is 'Epiglottis'.

    Which of the following options is incorrect about the larynx (sound box)?

    1. It is a bony box.

    2. Glottis is the opening into the larynx.

    3. During swallowing of food glottis is covered by epiglottis to prevent food entry into the larynx.

    4. All of these.
    Reveal answer Fill a bubble to check yourself
    A Correct answer
    Explanation
    • Larynx is a cartilaginous box containing nine pieces of cartilages.
    • Glottis is the opening from where esophagus and trachea gets seperated.
    • To prevent food from entering into the larynx while swallowing, the epiglottis covers the opening of the larynx.
    • So, the correct option is (A).

    Signet ring cartilage of larynx is

    1. Cricoid

    2. Arytenoid

    3. Thyroid

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

    The cricoid cartilage is a ring of hyaline cartilage located at the inferior aspect of the larynx and is the only complete ring of cartilage around the trachea. It has the shape of a signet ring, with a broad portion posterior to the airway (lamina of cricoid cartilage) and a narrower portion circling anteriorly (arch of cricoid cartilage).
