The pituitary gland is also referred to as the master gland because it controls several other hormone glands in your body, including the thyroid and adrenals, the ovaries and testicles.

What does the pituitary gland do?

By detecting the levels of hormones produced by glands under the pituitary’s control (target glands), the hypothalamus or the pituitary can determine how much stimulation the target glands need.

The pituitary has two distinct parts:

1️⃣ Front (anterior) lobe, which accounts for 80% of the pituitary gland’s weight

2️⃣ Back (posterior) lobe

The lobes are connected to the hypothalamus by a thin stalk that contains blood vessels and nerve cell projections (nerve fibers, or axons). The hypothalamus controls the anterior lobe by releasing hormones through the connecting blood vessels. It controls the posterior lobe through nerve impulses.

The hormones produced by the pituitary are not all produced continuously. Most are released in bursts every 1 to 3 hours, with alternating periods of activity and inactivity. Some of the hormones, such as growth hormone, and prolactin, follow a circadian rhythm.

The levels rise and fall predictably during the day, usually peaking just before awakening and dropping to their lowest levels just before sleep.

The levels of other hormones vary according to other factors. For example, in women, the levels of luteinizing hormone and follicle-stimulating hormone, which control reproductive functions, vary during the menstrual cycle.

In summary

  • The pituitary gland is situated in the base of the brain  near the hypothalamus.
  • The hypothalamus controls the pituitary by sending messages.
  • The pituitary gland is also referred to as the master gland because it controls several other hormone glands in your body.
  • The pituitary has two distinct parts, anterior and posterior.
  • The hormones produced by the pituitary are not all produced continuously.
