The 30-Second Exam Hall Shortcut: ⚡ Spot the False Prolactin Claim!

⏱️ Save ~50 seconds

Pituitary gland DOES secrete prolactin! Statement (d) claiming it does NOT is FALSE!

1 Read Statement (d): "It does not secrete prolactin". False! Prolactin (PRL) is secreted by pars distalis of adenohypophysis to regulate mammary gland development.

2 Since (d) is false, eliminate Option (3) immediately.

3 Check (a): Pituitary is divided into adenohypophysis (anterior) and neurohypophysis (posterior) -> TRUE.

4 Check (b): Secretes Follicle Stimulating Hormone (FSH, gonadotropin) -> TRUE.

5 Check (c): Secretes Melanocyte Stimulating Hormone (MSH from pars intermedia) -> TRUE.

6 Statements (a), (b), and (c) only are correct -> Option (2) in 15 seconds!

🛡️

Why You Can 100% Trust This Shortcut: NCERT Endocrine System verbatim: Pars distalis produces GH, PRL, TSH, ACTH, LH, and FSH; Pars intermedia produces MSH.

Step-by-Step Rigorous Workflow & Mathematical Proof

Step 1

Evaluate Statement (a): Anatomical Division of Pituitary

The pituitary gland (hypophysis) is lodged in a bony cavity called sella turcica and is attached to the hypothalamus by a stalk. Anatomically, it is divided into two main lobes: 1. Adenohypophysis: Comprising pars distalis (anterior pituitary) and pars intermedia. 2. Neurohypophysis: Pars nervosa (posterior pituitary).

\text{Pituitary Gland} = \text{Adenohypophysis} + \text{Neurohypophysis}

• Statement (a) is correct.

Step 2

Evaluate Statement (b): Secretion of FSH

Pars distalis region of the anterior pituitary secretes gonadotropins, specifically Luteinizing Hormone (LH) and Follicle Stimulating Hormone (FSH), which stimulate gonadal activity.

\text{Pars Distalis} \longrightarrow \text{FSH (Follicle Stimulating Hormone)}

• Statement (b) is correct.

Step 3

Evaluate Statement (c): Secretion of MSH

Pars intermedia secretes only one hormone in humans, called Melanocyte Stimulating Hormone (MSH), which acts on melanocytes to regulate skin pigmentation.

\text{Pars Intermedia} \longrightarrow \text{MSH (Melanocyte Stimulating Hormone)}

• Statement (c) is correct.

Step 4

Evaluate Statement (d): Secretion of Prolactin

Prolactin (PRL) is a primary peptide hormone secreted by the lactotroph cells of the pars distalis of the adenohypophysis. It regulates the growth of mammary glands and milk formation. Statement (d) asserts that the pituitary "does not secrete prolactin", which is scientifically false.

\text{Pituitary secretes Prolactin (PRL)} \implies \text{Statement (d) is FALSE}

• Therefore, statements (a), (b), and (c) only are correct.

4-Option Deep Scan

1 A

✗ Incorrect

Verdict & Scientific Reason:

Incomplete. Neglects statement (c), which is true (MSH is secreted by pars intermedia of pituitary).

⚠️

Student Fallacy (Why candidates pick this trap): Forgetting that pars intermedia is part of the pituitary gland.

2 B

✓ 100% Correct

Verdict & Scientific Reason:

Exact match: Statements (a), (b), and (c) are true; (d) is false because prolactin is a pituitary hormone.

💡

Why this is airtight: None; comprehensive endocrine knowledge.

3 C

✗ Incorrect

Verdict & Scientific Reason:

Incorrect. Statement (d) is completely false.

⚠️

Student Fallacy (Why candidates pick this trap): Believing prolactin comes from the ovaries or placenta instead of the anterior pituitary.

4 D

✗ Incorrect

Verdict & Scientific Reason:

Incomplete. Fails to include the valid anatomical division in statement (a).

⚠️

Student Fallacy (Why candidates pick this trap): Overlooking the anatomical division of the pituitary.

⚠️

NTA Trap Alert: Missing Negative Phrasing in Statement (d)

Statement (d) says "It DOES NOT secrete prolactin". Students who know prolactin is related to milk often misread it as "It secretes prolactin" and mark (d) as true!

🛡️ How to avoid the -1 mark: Watch out for words like "does not". Pituitary DOES secrete prolactin, so statement (d) is FALSE.
