Which one of the following paris is incorrectly mathced?

Options

A. Glucagon-Beta cells(source)
B. Somatostatin-Delta cells (Source)
C. Corpus luteum-Relaxis (secretion)
D. Corpus luteum-Relaxin (secretion)

Explanation

To determine which pair is incorrectly matched, we will analyze each option provided:

1. **Glucagon secreted by the beta cells**:
- This statement is incorrect. Glucagon is actually secreted by the **alpha cells** of the pancreas, while **beta cells** secrete insulin. Therefore, this pair is incorrectly matched.

2. **Somatostatin secreted by the delta cells**:
- This statement is correct. Somatostatin is indeed secreted by the **delta cells** of the pancreas.

3. **Corpus luteum provides the hormone relaxin**:
- This statement is also correct. The corpus luteum does produce relaxin, which helps in relaxing the pelvic muscles during pregnancy.

After analyzing all the options, we conclude that the first option is the only incorrectly matched pair.

**Final Answer**: The incorrectly matched pair is **Glucagon secreted by the beta cells**.
