The pituitary gland is a small, pea-sized organ located at the base of the brain that plays a crucial role in regulating critical body functions and general wellbeing. Often referred to as the “master gland,” it governs the activity of most other glands in the endocrine system and influences important processes like growth, metabolism, reproduction, and stress response.
What does the pituitary gland do?
As the master gland, the pituitary regulates various processes by secreting hormones into the bloodstream. Key roles include:
- Growth hormone (GH) - Stimulates growth in childhood and maintains tissues and organs
- Prolactin (PRL) - Initiates and sustains breast milk production after pregnancy
- Thyroid stimulating hormone (TSH) - Triggers thyroid gland to release thyroid hormones
- Adrenocorticotropic hormone (ACTH) - Prompts adrenal gland to produce cortisol
- Follicle stimulating hormone (FSH) and luteinizing hormone (LH) - Regulates sexual development and reproduction
How does it interact with other glands?
The pituitary communicates with the
hypothalamus as well as other glands like the
thyroid, adrenals and
gonads. It responds to hormonal signals from the hypothalamus by releasing hormones to target organs. This is known as the hypothalamic-pituitary axis.
What happens if the pituitary malfunctions?
When the pea-sized pituitary gland doesn’t function properly, it can give rise to several medical disorders:
- Gigantism - Excessive growth hormone causes abnormal growth
- Dwarfism - Insufficient growth hormones limit growth
- Infertility issues - Imbalanced sexual hormones disrupt ovulation, sperm production
- Thyroid disorders - Under- or over-secretion of TSH affects thyroid
