Question

Feeling the tremors of an earthquake a scared resident of the seventh floor of a multistoried building starts climbing down the stairs rapidly. Identify the correct hormone which is responsible for the initiation of this action?

• A. Glucagon
• B. Adrenaline
• C. Thyroxine
• D. Gastrin

Answer 1

The correct option is B

Adrenaline

The correct option is B.

Explanation for correct option:

1. Adrenaline is a catecholamine that is rapidly secreted from the adrenal medulla during an emergency.
2. This hormone causes an increase in heart rate and respiratory rate, as well as increased alertness, sweating, and pupillary dilation.
3. It also promotes glycogenolysis, which raises blood glucose levels.

Explanation for incorrect options:

Option A:

1. Glucagon is a hormone produced by the pancreas that aids in the regulation of our body's blood glucose (sugar) levels.
2. Glucagon raises blood sugar levels in the body and keeps them from falling too low.

Option C:

1. The thyroid gland produces the thyroxine hormone, which contains iodine.
2. Thyroxine speeds up chemical reactions in cells and aids in the regulation of growth and development.
3. Since it can affect the whole system of the body so proper thyroxine levels are critical for health.

Option D:

1. Gastrin hormone stimulates gastric juice secretion and is secreted into the bloodstream by the stomach wall in response to food presence.
2. It is found in the G cells of the duodenum and the antrum of the stomach.

Final Answer: The correct hormone which is responsible for this action by the resident is the Adrenaline hormone.
