Which hormone is an example of a steroid hormone?

• A. Insulin
• B. Estrogen
• C. Cortisol
• D. Adrenaline

Answer: (B)

The hormone that serves as an example of a steroid hormone is estrogen. Steroid hormones are derived from cholesterol and are characterized by their ability to easily pass through cell membranes due to their lipophilic nature. Once inside a target cell, they can bind to intracellular receptors and initiate changes in gene expression, leading to various physiological effects. Estrogen plays a crucial role in the regulation of the female reproductive system, including the menstrual cycle and development of secondary sexual characteristics. Like other steroid hormones, it is involved in numerous bodily processes, including metabolism, immune response, and the maintenance of bone density. Understanding hormone classifications is essential in physiology because it helps to clarify how different types of hormones interact with cells and how they exert their effects throughout the body.
