Which gland is located on the undersurface of the brain in the sella turcica?

The pituitary gland is located in the sella turcica, a saddle-shaped depression in the sphenoid bone at the base of the skull. This gland plays a crucial role in the endocrine system by secreting hormones that regulate various bodily functions, including growth, metabolism, and reproduction. Its strategic positioning under the brain allows it to effectively communicate with the hypothalamus, which controls various hormonal functions and regulates the pituitary gland's activity.

In contrast, the thyroid gland is located in the neck, the adrenal glands are situated on top of each kidney, and the pineal gland is found deep within the brain. Each of these glands serves distinct physiological roles but does not reside in the sella turcica like the pituitary gland. Understanding the specific locations and functions of these glands is important for comprehending how they interact within the body's endocrine system.
