Verified step by step guidance

Step 1: Begin by identifying the anatomical location mentioned in the question, the 'sella turcica.' The sella turcica is a saddle-shaped depression in the sphenoid bone located at the base of the skull.

Step 2: Understand the function of the sella turcica. It serves as a protective enclosure for an important endocrine gland, which is situated within this bony structure.

Step 3: Review the endocrine glands listed in the options: adrenal gland, thyroid gland, pituitary gland, and pineal gland. Determine which gland is anatomically located in the sella turcica.

Step 4: Recall that the pituitary gland, also known as the hypophysis, is housed in the sella turcica. It is a pea-shaped gland that plays a critical role in regulating various hormones in the body.

Step 5: Confirm that the other glands listed (adrenal gland, thyroid gland, and pineal gland) are located in different regions of the body. For example, the adrenal glands are above the kidneys, the thyroid gland is in the neck, and the pineal gland is in the brain but not in the sella turcica.
