Which is incorrect

Options

A. Glucagon is produced by pancreas
B. Androgen is produced by ovary
C. Thyroxine is secreted by thyroid
D. Oxytocin is produced by pituitary.

Answer

To determine which statement is incorrect, we will analyze each option step by step.

### Step 1: Analyze the first option
**Statement:** Glucagon is produced by the pancreas.

**Explanation:** Glucagon is indeed a peptide hormone that is secreted by the alpha cells of the islets of Langerhans in the pancreas. Therefore, this statement is correct.

### Step 2: Analyze the second option
**Statement:** Androgen is produced by the ovary.

**Explanation:** Androgens are primarily produced by the adrenal glands and also by the ovaries. Since the statement mentions that androgens are produced by the ovary, it is partially correct, but it does not mention the adrenal gland, which is a significant source. However, since androgens are produced in both locations, we can consider this statement as correct in a broader context.

### Step 3: Analyze the third option
**Statement:** Thyroxine is secreted by the thyroid.

**Explanation:** Thyroxine (T4) is indeed the main hormone secreted by the thyroid gland into the bloodstream. Thus, this statement is correct.

### Step 4: Analyze the fourth option
**Statement:** Oxytocin is produced by the pituitary.

**Explanation:** Oxytocin is produced by the hypothalamus and is then transported to the posterior pituitary gland, where it is stored and released into the bloodstream. Therefore, this statement is incorrect.

### Conclusion
After analyzing all the options, the incorrect statement is: **Oxytocin is produced by the pituitary.**

### Final Answer
The incorrect option is: **Oxytocin is produced by pituitary.**
