Choose the correct answer from the alternatives given.
The Adams apple is formed predominantly, by which of the following structures?

  1. Larynx

  2. Pharynx

  3. Oesophagus

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

The Adam's apple is a laryngeal protrusion that is formed by the angle of the thyroid cartilage surrounding the larynx and is seen especially in males. So, the correct option is 'larynx'.

Nasal chamber is divided in tow parts by?

  1. Sphenoid bone

  2. Palatine bone

  3. Mesethemoid cartilage

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

The nasal cavity is divided into two lateral halves by the nasal septum, which is formed by the vomer, the perpendicular plate of the ethmoid bone, and the septal cartilage.

Tuberculum and capitulum are related to

  1. Skull

  2. Pelvic girdle

  3. Ribs

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

At the spinal column, the rib starts with the rib head (caput costae or capitulum). The rib bone progresses backwards via the rib neck (collum costae) to the rib tubercle (tuberculum costae). This is where the rib body (corpus costae) begins, which curves round to the front with the rib angle (angulus costae).

What do the trachea and bronchi possess in their wall  of the respiratory tract in man?

  1. C-shaped cartilagenous rings

  2. C-shaped bony rings

  3. V-shaped bony rings

  4. V-shaped cartilagenous rings
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The trachea, primary, secondary and tertiary bronchi, and initial bronchioles are supported by incomplete cartilaginous rings. 


So, the correct answer is 'C-shaped cartilaginous rings'

Lingula structure originates from

  1. Superior side of left lung

  2. Superior side of right lung

  3. Inferior side of right lung

  4. Inferior side of left lung
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

  • The left lung is divided into two lobes, an upper and a lower, by the oblique fissure, which extends from the coastal to the mediastinal surface of the lung both above and below the hilum.
  •  The left lung, unlike the right, does not have a middle lobe, though it does have a homologous feature, a projection of the upper lobe termed the "lingula". 
  • Its name means "little tongue". Hence, the Lingula structure originates from the Superior side of the left lung.
So, the correct answer is 'Superior side of left lung'.

In nasal passage, the turbinal bones are present in which of the following groups?

  1. In all vertebrates

  2. Amphibia

  3. Mammals

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

In mammals, the nasal chambers are called as nasal vestibules. The nasal vestibules are formed by invagination of skin in embryonic stage and hence nasal vestibules have hair and sebaceous glands. In this manner dust particles cannot cross nasal vestibules. The remaining part of nasal chamber is surrounded by three types of bones- nasal, maxilla and ethmoids. At several places in the nasal passage these bones form outgrowths. These outgrowths are called turbinal bones. Due to these outgrowths, the nasal passage is long and spiral. This helps in making the temperature of air equal to body temperature before it reaches the lungs and does not allows unwanted particles like dust to reach lungs.

Therefore, the correct answer is option C.

Name the organ which divides to form bronchi. 

  1. Larynx

  2. Nose

  3. Tubes

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

A trachea is a connects the larynx and the lungs. It is made up of cartilaginous rings which prevent it from collapsing. It divides into bronchi which further separates to form bronchioles and terminates into air filled lobes known as alveoli.

So, the correct answer is option D.

Trachea is lined with incomplete rings of

  1. Fibrous cartilage

  2. Calcified cartilage

  3. Elastic cartilage

  4. Hyaline cartilage
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
The trachea is also called as windpipe. It is a cartilaginous tube which connects pharynx and larynx to the lungs, allowing passage of air. The wall of the trachea is lined by C shaped incomplete cartilaginous rings to protect it from collapsing during the breathing process due to pressure exerted on its walls by the air. These incomplete rings are made up of hyaline cartilage.
So, the correct answer is 'Hyaline cartilage'.

Choose the correct answer from the alternatives given.
The is an airway that connects the nose and mouth with the

  1. oral cavity; larynx

  2. trachea; pharynx

  3. pharynx; trachea

  4. pharynx; larynx
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The trachea or the windpipe is an airway that is a cartilaginous tube that connects the pharynx and larynx to the lungs, allowing the passage of air. It connects the nose and the mouth with the pharynx and larynx. So, the correct option is 'pharynx; larynx'.

Choose the correct answer from the alternatives given.
Simple squamous non-ciliated epithelium is found in

  1. alveoli

  2. bronchi

  3. bronchioles

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

Simple squamous non-ciliated epithelia are found in capillaries, alveoli, and other tissues where rapid diffusion is required. Cells are flat with flattened and oblong nuclei. It is also called pavement epithelium due to its tile-like appearance. The bronchi are lined by ciliated, pseudostratified columnar epithelium and bronchioles are lined by simple cuboidal epithelium. So, the correct option is 'alveoli'.
