Which one is primary sex organ? 

  1. Penis

  2. Scrotum

  3. Testis

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

The primary sex organ in the male is testis. Besides producing sperms they also produce hormones. Penis and prostate are examples of secondary sex organs. The scrotum is not a sex organ.

Hence, option 'Testis' is correct.

Testes are masses of coiled

  1. Uriniferous tubules

  2. Malpighian tubules

  3. Vasa efferentia

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

The tubular structures present inside the testis are known as seminiferous tubules. These tubules are responsible for producing the sperm cells through a process called spermatogenesis. 

The uriniferous tubule is  a urine-bearing tubule in a nephron of a kidney. Malpighian tubules are slender tubes normally found in the posterior regions of arthropod alimentary canals. 
Vasa efferentia is the several highly convoluted tubules that lead from the  testis. 
Therefore, the correct answer is option D.

Testes are placed inside the

  1. Abdominal cavity

  2. Urinary bladder

  3. Scrotum

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

The testes are located outside the abdominal cavity in a pouch of skin called the scrotum. This placement is essential because sperm production requires a temperature slightly lower than the core body temperature.

Head of epididymis present at head of testis is

  1. Caput epididymis

  2. Cauda epididymis

  3. Vas deferens

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

Head of the epididymis of the sperm which receives spermatozoa via the efferent ducts of the mediastinum of the testis which is also called as Caput epididymis.

So the correct option is 'Caput epididymis.'

Mammary glands are without teats in

  1. Prototheria

  2. Metatheria

  3. Eutheria

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

Monotremes or Prototheria are mammals that do not give birth to live young ones. Instead, they lay eggs and nurse them after they have hatched. They have mammary glands but no teats. They simply pour milk onto their skin and it gets collected in a pouch where the babies can drink it from.

So the correct answer is 'Prototheria'.

Cloaca is

  1. Common aperture for digestive and urinary systems

  2. Common aperture for digestive, urinary and reproductive systems

  3. Common chamber in which reproductive, urinary and digestive tracts open

  4. Common chamber for digestive and urinary tracts
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Cloaca is a chamber or cavity that acts as an exit channel in organisms like reptiles, birds and amphibians.

It is a common chamber where reproductive, urinary and digestive tracts open.
So the correct answer is 'Common chamber in which reproductive, urinary and digestive tract open'

Choose the correct answers from the alternatives given.
Generally the breathing system in birds:

  1. is identical to the human breathing system

  2. is merely accelerated by the flight muscles

  3. resembles the positive pressure system of a frog

  4. requires a flow-through bronchi-lung so constant oxygen absorption can meet the high oxygen demand
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Unidirectional flow means that air moving through bird lungs is largely 'fresh' air & has a higher oxygen content.  So, in bird lungs, more oxygen is available to diffuse into the blood. 

So the correct answer is "requires a flow-through bronchi-lung so constant oxygen absorption can meet the high oxygen demand".

Which structure gives us ability to speech?

  1. Epiglottis

  2. Vocal cord

  3. Larynx

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

The vocal cord has two small bands of muscle within the larynx. These muscles vibrate to produce the voice. It is a V shape inside larynx. When we talk, the vocal cord tightens up and move closer together and air from lungs forced between them and make then vibrate, producing the sound.

So the option B, Vocal cord is correct.

Choose the correct answer from the alternatives given.
Which of the following is the cartilaginous structure that folds down to meet the uprising larynx to close off the airway during swallowing?

  1. Trachea

  2. Epiglottis

  3. Cricoid cartilage

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

A flap-like epiglottis closes the opening to the larynx during swallowing to prevent swallowed matter from entering the trachea (airway). So, the correct option is 'Epiglottis'.
