Question

The type of glands in which the entire glandular cell when filled with secretary products is discharged as a part of the secretion
A) Merocrine
B ) Holocrine
C) Exocrine
D) Apocrine

Answer 1

Hint: Glandular cells are multi layered cells present in the intestinal lining to help in the absorption of nutrients and their main function is secretion. Sebaceous glands are the main example of this.

Complete answer:
First of all, you should know what glandular cells are. Glandular cells are cuboidal shaped and multi layered cells and these cells have a single large nucleus. The basement membrane of glandular cells is always present and it is present in order to separate the epithelial tissue from the other tissues.
Their main function is secretion. These are present in intestinal lining and help in the absorption of nutrients and apart from this these cells also perform various reproductive functions. Entire glandular cells when filled with secretary products and get discharged as a part of secretion in holocrine glands and sebaceous glands use holocrine method of secretion.
So, if we look at options now. Option A is Merocrine. It is an incorrect option since in holocrine glands, the glandular cell is discharged as a part of secretion not in the merocrine gland and therefore it is incorrect and this option gets eliminated.
Moving to option B which is Holocrine. This option is the correct one since glandular cells when filled with secretary products get discharged as a part of secretion in holocrine glands. Therefore, it is the correct option.
Moving to option C which is Exocrine, it is incorrect one since glandular cells are not discharged as a part of secretion in this gland.
Last option D is Apocrine, it is also incorrect because glandular cells are not discharged as a part of secretion in this gland.

Thus, the correct option is B which is Holocrine.

Note: The entire glandular cells break down and the products are discharged as the secretion in the holocrine glands. Mainly the sebaceous glands uses the holocrine glands in secretion. These cells are uninucleated and their main function is secretion.
