  2. stratum spinosum and stratum granulosum

  3. stratum granulosum and stratum corneum

  4. epidermis and dermis

D Correct answer
Explanation

The basement membrane is a thin sheet of fibers. It lies between the epidermis and dermis and keeps the outer layer adhered closely to the lower layer.

Multiple choice

The ducts in the male reproductive system are lined by ______________.

  1. simple squamous epithelium

  2. transitional epithelium

  3. cuboidal epithelium

  4. a pseudostratified columnar epithelium
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Yes, it is the correct answer. A pseudostratified columnar epithelium forms the linning of the respiratory tract and of the ducts in the male reproductive system.

Multiple choice

Which of the following corpuscles respond to deep pressure?

  1. Merkel's touch corpuscles

  2. Meissner's corpuscles

  3. Pacinian corpuscles

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

Yes, Pacinian corpuscles are simple nerve endings covered with multilamellar, ovoid structures resembling small onions. These corpuscles respond to deep pressure.

Multiple choice

The trigone is highly sensitive triangular structure of the urinary bladder in mammals. It lies _________-.

  1. in internal surface of fundus of bladder

  2. below apex of urinary bladder

  3. in the body of bladder

  4. below neck of bladder

  5. in the fundus of gallbladder
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The fundus of the urinary bladder is the base of the bladder formed by the posterior wall. The smooth muscle of bladder contracts to expel urine from the body. The trigone lies in the internal surface of fundus of bladder.

Multiple choice

  1. internal urethral orifice

  2. membranous part

  3. external urethral orifice

  4. prostatic portion of urethra

  5. base of the urethra
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

It is the part of the male urethra lying between the layers of the urogenital diaphragm and connects the parts of the urethra passing through the prostate gland and the penis. The second constriction of male urethra lies in membranous part.

Multiple choice

Consider the following statements regarding different types of animals-

  1. Cnidarians are acoelomate
  2. All sponges (Porifera) are marine
  3. Flatworms (Platy helminthes) can reproduce asexually
  4. In arthropods, fertilization is always internal Which of these statement is/are correct?

  1. 1, only

  2. 1 and 3

  3. 2, 3 and 4

  4. 2 and 4
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Cnidarians (jellyfish, sea anemones) have a simple body organization without a true coelom, making them acoelomate. Some sponges like Spongilla inhabit freshwater, so not all are marine. Flatworms can reproduce asexually through transverse fission. Many arthropods like crustaceans have external fertilization where eggs are released into water.

Multiple choice

Where is the vocal box present?

  1. It is present at the upper end of wind pipe.

  2. It is present at the lower end of wind pipe.

  3. It is present on the left side of wind pipe.

  4. It is present on the right side of wind pipe.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The voice box or larynx is located at the upper end of the windpipe (trachea), just below the epiglottis. This positioning allows it to protect the airway during swallowing while producing sound. Options B, C, and D incorrectly place it at the lower end or on the sides.
