The pituitary gland is within the sella turcica or the hypophyseal fossa. This structure is present near the center at the base of the cranium and is fibro-osseous. The anatomical boundaries of the gland have clinical and surgical significance. Sella turcica is a concave indentation in the sphenoid bone.
What is the structure of pituitary gland?
The pituitary gland is a pea-sized oval structure, suspended from the underside of the brain by the pituitary stalk (known as the infundibulum). It sits within a small depression in the sphenoid bone, known as the sella turcica (”Turkish saddle”).
Where does the pituitary gland sit?
Your pituitary (hypophysis) is a pea-sized endocrine gland at the base of your brain, behind the bridge of your nose and directly below your hypothalamus. It sits in an indent in the sphenoid bone called the sella turcica.
What brain structures are near the pituitary gland?
The pituitary gland is small and oval-shaped. It’s located behind your nose, near the underside of your brain. It’s attached to the hypothalamus by a stalklike structure. The hypothalamus is a small area of your brain.
What structure is found anterior to the pituitary gland?
Located at the base of the brain, the pituitary gland is protected by a bony structure called the sella turcica of the sphenoid bone. Median sagittal through the hypophysis of an adult monkey.

What is the structure and function of pituitary gland?
The pituitary gland, also known as the hypophysis, is a small, pea-sized gland located at the base of our brains. It is referred to as the “master gland” of the human body, as it releases a variety of hormones that circulate our system and aid in maintaining our internal homeostasis.
What happens if your pituitary gland isn’t working properly?
For example, if the pituitary gland does not produce enough growth hormone in a child, they may have a permanently short stature. If it doesn’t produce enough follicle-stimulating hormone or luteinizing hormone, it might cause problems with sexual function, menstruation, and fertility.

Hypopituitarism is an underactive pituitary gland that results in deficiency of one or more pituitary hormones. Symptoms of hypopituitarism depend on what hormone is deficient and may include short height, infertility, intolerance to cold, fatigue, and an inability to produce breast milk.
Is there a blood test for pituitary function?
Blood tests help doctors detect many hormonal abnormalities associated with pituitary tumors. For example, a blood test can reveal high levels of the hormone prolactin, which occurs in a condition called hyperprolactinemia. This can indicate the presence of a pituitary tumor called a prolactinoma.
What is the role of pituitary gland?
The pituitary gland is referred to as the “master gland” because it monitors and regulates many bodily functions through the hormones that it produces, including: Growth and sexual/reproductive development and function.

Can you live without a pituitary gland?
The pituitary gland is called the master gland of the endocrine system. This is because it controls many other hormone glands in the body. According to The Pituitary Foundation, without it, the body wouldn’t reproduce, wouldn’t grow properly and many other bodily functions just wouldn’t function.
How can you tell if a pituitary tumor is benign or malignant?
How is pituitary cancer diagnosed? MRI or CT scans can detect tumors in the pituitary gland. And blood and urine tests can determine hormone levels. Even under a microscope, it’s difficult to recognize the difference between a cancerous and a noncancerous pituitary tumor.
