The hormones secreted from posterior lobe of pituitary gland are

Options

A. short peptides
B. long peptides
C. amino acid derivatives
D. polypeptides

Answer

To answer the question regarding the hormones secreted from the posterior lobe of the pituitary gland, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Pituitary Gland Structure**:
- The pituitary gland consists of two main lobes: the anterior lobe and the posterior lobe. Each lobe has different functions and secretes different hormones.

2. **Focus on the Posterior Lobe**:
- The posterior lobe of the pituitary gland is responsible for the secretion of specific hormones. It does not produce hormones itself but stores and releases hormones produced in the hypothalamus.

3. **List the Hormones Secreted by the Posterior Lobe**:
- The two primary hormones secreted from the posterior lobe are:
- **Vasopressin (also known as Antidiuretic Hormone or ADH)**: This hormone helps regulate water balance in the body by controlling the amount of water reabsorbed by the kidneys.
- **Oxytocin**: This hormone plays a crucial role during childbirth and lactation. It stimulates uterine contractions during labor and promotes milk ejection during breastfeeding.

4. **Summarize the Functions of Each Hormone**:
- **Vasopressin**: Regulates water retention and salt balance in the body.
- **Oxytocin**: Facilitates childbirth and lactation, and is also involved in social bonding.

5. **Conclude the Answer**:
- Therefore, the hormones secreted from the posterior lobe of the pituitary gland are **Vasopressin (ADH)** and **Oxytocin**.

### Final Answer:
The hormones secreted from the posterior lobe of the pituitary gland are **Vasopressin (ADH)** and **Oxytocin**.
