ANATOMY

Detailed explanation-1: -What Does the Endocrine System Do? Endocrine glands release hormones into the bloodstream. This lets the hormones travel to cells in other parts of the body. The endocrine hormones help control mood, growth and development, the way our organs work, metabolism, and reproduction.

Detailed explanation-2: -Puberty occurs when a part of the brain called the hypothalamus releases gonadotropin-releasing hormone (GnRH). This hormone stimulates the pituitary gland (a small gland at the base of the brain) to release two other hormones: luteinizing hormone (LH) and follicle-stimulating hormone (FSH).

Detailed explanation-3: -Summary: Puberty is initiated by gonadotropin-releasing hormone from the hypothalamus followed by a complex sequence of endocrine changes and is regulated by both genetic and environmental factors.

Detailed explanation-4: -It happens when the pituitary gland releases sex hormones called gonadotropins, which stimulate the development of the ovaries in girls and testes and boys, which in turn triggers the female sex hormone estrogen in girls and the male sex hormone testosterone in boys.

Detailed explanation-5: -The glands and organs that make hormones and release them directly into the blood so they can travel to tissues and organs all over the body. The hormones released by the endocrine system control many important functions in the body, including growth and development, metabolism, and reproduction.
