Etuliitesanavartalo, also known as the anterior pituitary, is the front section of the pituitary gland, a small endocrine gland located at the base of the brain. It plays a crucial role in regulating a wide array of bodily functions by producing and secreting various hormones. These hormones are essential for growth, metabolism, reproduction, and stress response.

The anterior pituitary is composed of several types of endocrine cells, each responsible for synthesizing and releasing specific hormones. These include somatotrophs, which produce growth hormone (GH), crucial for bone and muscle development. Lactotrophs secrete prolactin, which stimulates milk production in females after childbirth. Gonadotrophs are responsible for producing follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which regulate the reproductive system in both males and females. Thyrotrophs produce thyroid-stimulating hormone (TSH), which controls the thyroid gland's hormone production. Finally, corticotrophs secrete adrenocorticotropic hormone (ACTH), which stimulates the adrenal glands to produce cortisol, a hormone involved in stress management and metabolism.

The activity of the anterior pituitary is regulated by the hypothalamus, a region of the brain located directly above it. The hypothalamus releases releasing and inhibiting hormones that travel through a specialized portal blood system to the anterior pituitary, either stimulating or suppressing the release of its hormones. This intricate feedback loop ensures that hormone levels in the body are maintained within a healthy range. Disorders affecting the anterior pituitary can lead to a variety of conditions, such as growth deficiencies, reproductive issues, and metabolic imbalances.
