Where does the pituitary gland sit?
Pituitary gland sits just below the hypothalamus over sella turcica at the base of skull.
Were is the pituitary?
The pituitary gland is a small endocrine gland in the brain. It sits a bony structure on the cranial floor called the Sella Turcica, which translates to Turkish saddle, named for the shape of the structure. When looking at the blood vessels of the brain the pituitary is very easy to locate. It sits in the middle of the circle of Willis, a ring a blood vessels at the heart of the 'lobster-like' network.
Where can a Pituitary gland tumor be located?
The pituitary gland, or hypophysis, is an endocrine gland about the size of a pea and weighing 0.5 g (0.02 oz.). It is a protrusion off the bottom of the hypothalamus at the base of the brain, and rests in a small, bony cavity (sella turcica) covered by a dural fold (diaphragma sellae). The pituitary fossa, in which the pituitary gland sits, is situated in the sphenoid bone in the middle cranial fossa at the base of the brain.
Which gland encircles the bladder in the male?
There is no gland that encircles the bladder. The prostate gland sits at the base of the bladder; maybe that is what you were referring to.
Is kidney inferior to the adrenal gland?
Yes, the adrenal glands sit on top of each of the kidneys. They are triangular in shape, while the kidneys are bean shaped. Source: A RN in NJ My head
What houses the pituitary gland?
The pituitary gland sits in a bony structure in the skull known as the sella turcica. The sella turcica, also known as "Turk's Saddle", is a depression in the sphenoid bone.
What part of the brain sits in the sella turcica?
contains the pituitary glandThe Sella Turcica is located on the superior surface of the Sphenoid Bone. The saddle shaped prominence is called the sella turcica. The seat of the saddle is called the hypophyseal fossa which forms the enclosure for the pituitary gland.
Where does the pituitary gland sit?
Pituitary gland sits just below the hypothalamus over sella turcica at the base of skull.
Which bone serves as an enclosure for the pituitary gland?
Sphenoid Bone. Along the midline within the cranial cavity, a portion of the sphenoid bone indents to form the "saddle-shaped" Sella Turcica. The pituitary gland occupies this depression. The Sphenoid bone also contains two sphenoidal sinuses.
What is pituitary of brain?
The pituitary of the brain sits in a tiny bony space called the sella turcica.

Describe the pituitary gland and its location?
The pituitary gland, or hypophysis, is found at the base of the brain below the hypothalamus and the two structures are connected via the infundibulum, or pituitary stalk, which carries both axons and blood vessels.The pituitary gland is about 1- 1.5 cm in diameter and weighs approximately 0.5g although it tends to weigh approximately 20% more in women and may increase by 10% during pregnancy. It sits in the sella turcica which is a depression of the sphenoid bone at the base of the skull and lies behind the sphenoid sinus.The top of the sella turcica is covered by a diaphragm, which has a foramen in the centre through which the infundibulum passes.Superior to the diaphragm is the optic chiasm.The pituitary gland can be divided into two functionally and embryologically distinct parts. These are the anterior pituitary, or adenohypophysis, and the posterior pituitary, or neurohypophysis.The anterior pituitary makes up 75% of the total weight of the pituitary. The pars distalis forms the major part of the gland. The pars intermedia is rudimentary in man. The pars tuberalis runs up the pituitary stalk.The posterior pituitary is made up of neuronal processes and glia as an extension of the hypothalamus and its major part is the pars distalis, which lies behind the anterior pituiary in the sella turcica.
What structure connects the pituitary gland to the brain?
In vertebrate anatomy the pituitary gland, or hypophysis, is an endocrine gland about the size of a pea and weighing 0.5 g (0.02 oz.), in humans. It is a protrusion off the bottom of the hypothalamus at the base of the brain, and rests in a small, bony cavity (sella turcica) covered by a dural fold (diaphragma sellae). The pituitary is functionally connected to the hypothalamus by the median eminence via a small tube called the infundibular stem (Pituitary Stalk). The pituitary fossa, in which the pituitary gland sits, is situated in the sphenoid bone in the middle cranial fossa at the base of the brain. The pituitary gland secretes six hormones that regulate homeostasis.
Empty sella syndrome?
DefinitionEmpty sella syndrome is a condition in which the pituitary gland shrinks or becomes flattened.Causes, incidence, and risk factorsThe pituitary gland is a small gland located at the base of the brain. It sits in a saddle-like compartment in the skull called the "sella turcica," which in Latin means "Turkish saddle."When the pituitary gland shrinks or becomes flattened, it cannot be seen on MRIscans, giving the appearance of an "empty sella." This is referred to as empty sella syndrome.The pituitary makes several hormones that control the other glands in the body, including the:Adrenal glandsOvariesTesticlesThyroidPrimary empty sella syndrome occurs when a hole in the membrane covering the pituitary gland allows fluid in, which presses on the pituitary.Secondary empty sella syndrome occurs when the sella is empty because the pituitary gland has been damaged by:A tumorRadiation therapySurgeryEmpty sella syndrome may be seen in a condition called pseudotumor cerebri. This is a condition seen most commonly in obese women.SymptomsOften, there are no symptoms or loss of pituitary function.Patients with empty sella syndrome may have symptoms caused by a partial or complete loss of pituitary gland function. For more information, see hypopituitarism.Symptoms include:Erectile dysfunction (impotence)HeadachesIrregular or absent menstruationLow sexual desire (low libido)Nipple dischargeSigns and testsPrimary empty sella syndrome is most often discovered during radiological imaging of the brain. Pituitary function is usually normal.The health care provider may test pituitary gland function to make sure that the gland is working normally.Sometimes tests for high pressure in the brain will be done, such as:Examination of the retina by an ophthalmologistLumbar puncture (spinal tap)The hormone prolactin is a little high in a small percentage of patients, which may interfere with the normal function of the testicles or ovaries.TreatmentFor primary empty sella syndrome:There is no specific treatment if pituitary function is normal.Medications, such as bromocriptine, which lower prolactin levels, may be prescribed if the prolactin levels are high and interfering with function of the ovaries or testes.For secondary empty sella syndrome:Treatment involves replacing the hormones that are lacking.Expectations (prognosis)Primary empty sella syndrome does not cause health problems, and it does not affect life expectancy.ComplicationsComplications of primary empty sella syndrome include mild hyperprolactinemia.Complications of secondary empty sella syndrome are related to the cause of pituitary gland disease or to the effects of too little pituitary hormone.Calling your health care providerContact your health care provider if you develop symptoms of abnormal pituitary function, such as a disrupted menstrual cycle or impotence.ReferencesMelmed S, Kleinberg D.

Which gland sits on the thyroid gland?
The parathyroids are tiny glands that sit up next to the thyroid gland.
Which gland encircles the bladder in the male?
There is no gland that encircles the bladder. The prostate gland sits at the base of the bladder; maybe that is what you were referring to.
