Growth hormone is also known by which other name?

Growth hormone is commonly referred to as somatropin. This name is used in both human medicine and veterinary applications to refer to the polypeptide hormone produced by the anterior pituitary gland that stimulates growth, cell reproduction, and cell regeneration. Somatropin plays a crucial role in growth regulation and metabolism in humans.

The other options represent different hormones and have distinct functions within the endocrine system. Oestrogen is primarily a female sex hormone involved in the regulation of the menstrual cycle and fertility. Prolactin is a hormone that stimulates milk production in mammals following childbirth. Thyroid hormone encompasses a group of hormones produced by the thyroid gland, which are involved in regulating metabolism, energy generation, and overall growth and development in the body. Recognizing the functions and roles of these different hormones highlights the specificity of somatropin as an agent related specifically to growth and development.
