A specific hormone is responsible for causing a disease that is characterized by excessive urination . The urine analysis of such a person reveals that the urine is dilute , has high pH and secretion of hormone from

Options

A. The gland which is heterocrine in nature
B. The gland which stores the hypothalamic
C. The gland situated on the dorsal side of the forebrain.
D. The gland which is influenced by the hypothalamic hormones

Answer

To solve the question, we need to analyze the information provided and identify the specific hormone and the gland responsible for the symptoms described.

### Step-by-Step Solution:

1. **Understand the Symptoms**: The question mentions excessive urination, dilute urine, and high pH. These symptoms suggest a problem with water reabsorption in the kidneys.

**Hint**: Look for conditions that lead to increased urine output and changes in urine composition.

2. **Identify the Disease**: The symptoms described are characteristic of a condition known as diabetes insipidus. This condition is primarily caused by a deficiency of the hormone vasopressin (also known as antidiuretic hormone, ADH).

**Hint**: Consider diseases that affect hormone levels and lead to polyuria (excessive urination).

3. **Determine the Hormone**: Vasopressin is produced in the hypothalamus and stored and released from the posterior pituitary gland. A deficiency in this hormone leads to the inability to concentrate urine, resulting in dilute urine and excessive urination.

**Hint**: Think about where vasopressin is produced and stored in the body.

4. **Identify the Gland**: The posterior pituitary gland is responsible for the secretion of vasopressin. Therefore, the correct answer to the question regarding the gland involved is the posterior pituitary.

**Hint**: Recall the functions of the pituitary gland and its relationship with the hypothalamus.

5. **Review the Options**: Based on the analysis, the correct answer is the gland that stores and releases vasopressin, which is the posterior pituitary gland.

**Hint**: Cross-check the options provided in the question to ensure the correct gland is identified.

### Final Answer:
The specific hormone responsible for causing the disease characterized by excessive urination is vasopressin, and it is secreted by the posterior pituitary gland. The disease is known as diabetes insipidus.
