Ovary(Endocrine Gland), FSH(Hormone), Stimulates follicular development(Function)

Show Answer

Correct Answer :

Option C

Leydig cells(Endocrine Gland), Androgen(Hormone), Initiates the production of sperms(Function)

Solution :

The correct option is: Leydig cells (Endocrine Gland), Androgen (Hormone), Initiates the production of sperms (Function).

Let us break down why this option is correct and evaluate all the choices step-by-step to understand their biological functions:

1. Understanding Leydig Cells, Androgens, and Spermatogenesis (The Correct Option):
Leydig cells (also known as interstitial cells of Leydig) are located in the connective tissue surrounding the seminiferous tubules in the testes. They act as endocrine cells by secreting male sex hormones, primarily testosterone, which is a type of androgen. Androgens play a crucial role in male reproduction; specifically, they act locally on the seminiferous tubules to stimulate and initiate spermatogenesis (the production of sperms). Thus, this matching is physiologically accurate.

2. Analyzing the Incorrect Options:
Let's analyze the other options to understand why they are incorrect matching pairs:

Sertoli cells, Testosterone, Development of secondary sexual characteristics: Sertoli cells are "nurse" cells located within the seminiferous tubules that support spermatogenesis. They do not secrete testosterone; testosterone is secreted by Leydig cells. Additionally, the development of male secondary sexual characteristics is regulated by testosterone, but Sertoli cells do not produce it.
Placenta, Estrogen, Initiates secretion of milk: Although the placenta secretes estrogen and progesterone during pregnancy, it does not initiate the secretion of milk. The hormone responsible for initiating milk secretion is prolactin, which is produced and released by the anterior pituitary gland.
Ovary, FSH, Stimulates follicular development: Follicle-Stimulating Hormone (FSH) is indeed responsible for stimulating follicular development in the ovaries. However, FSH is synthesized and secreted by the anterior pituitary gland, not the ovary itself. The ovary acts as the target organ for FSH rather than its endocrine gland of origin.
