Select the correct statement.

Options

A. Neural co-ordination is fast and long lived.
B. Hypothalamus forms the basal part of diencephalon.
C. GH-RH is released by pituitary gland.
D. Pars distalis is the part of neurohypophysis in pituitary gland

Answer

To solve the question, we need to analyze each of the four statements provided and determine which one is correct. Let's break down the statements step by step.

### Step 1: Analyze the First Statement
**Statement:** Neural coordination is fast and long-lived.
- **Analysis:** Neural coordination is indeed fast due to the rapid transmission of signals through neurons. However, it is typically short-lived because neural signals are quickly terminated after the response is generated.
- **Conclusion:** This statement is **incorrect**.

### Step 2: Analyze the Second Statement
**Statement:** The hypothalamus is part of the forebrain where neurosecretory cells are present, and it secretes hormones.
- **Analysis:** The hypothalamus is indeed a part of the forebrain and contains neurosecretory cells that produce hormones. It plays a crucial role in regulating various bodily functions through hormone secretion.
- **Conclusion:** This statement is **correct**.

### Step 3: Analyze the Third Statement
**Statement:** Growth hormone-releasing hormone (GHRH) is released by the pituitary gland.
- **Analysis:** GHRH is actually produced and released by the hypothalamus, not the pituitary gland. The pituitary gland releases growth hormone (GH) in response to GHRH.
- **Conclusion:** This statement is **incorrect**.

### Step 4: Analyze the Fourth Statement
**Statement:** Pars distalis is part of the neurohypophysis in the pituitary gland.
- **Analysis:** The pars distalis is actually part of the anterior pituitary, while the neurohypophysis refers to the posterior pituitary. Therefore, this statement is also incorrect.
- **Conclusion:** This statement is **incorrect**.

### Final Conclusion
After analyzing all four statements, the only correct statement is the second one regarding the hypothalamus.

### Answer:
The correct statement is: **The hypothalamus is part of the forebrain where neurosecretory cells are present, and it secretes hormones.**
