contains the pituitary gland
The 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.

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.
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.
Three main division of the brain?
The three sections of the brain are:Cerebrum: the superior-most region of the central nervous system (CNS). It's divided into approximately symmetric left and right cerebral hemispheres, and controls all voluntary actions in the body.Cerebellum: region of the brain that plays an important role in motor control. It sits at the back of your head.Brain stem: is the posterior part of the brain, adjoining and structurally continuous with the spinal cord. The brain stem has many basic functions including heart rate, breathing, sleeping, and eating.
In which part of the can you find the pituitary gland?
The pituitary descends from the inferior anterior part of the hypothalamus in the brain. Is sits in a structure on the cranial floor called the sellae turcica (turkish saddle). It is surrounded by an iomportant ring of arterier called the circle of willis.
What are the functions of diencephalon in the brain?
The diencephalon is the region of the brain that sits on top of the brainstem, below the telencephalon. It includes the thalamus and hypothalamus. Parts of diencephalon perform numerous functions, from regulating wakefulness to the control of the autonomic nervous system.
What is pituitary of brain?
The pituitary of the brain sits in a tiny bony space called the sella turcica.
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.
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.
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.

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.
How does the brain lie?
the brain sits where your scull is at the top of your head stupid!!:)
What part of the body tells you to grow taller?
The pituitary gland controls growth. It is about the size of a pea and sits behind your eyes in the centre of your brain.
Which area of the brain works with the eyes?
The Optical lobe. (Or something like that) It sits at the back of your brain.
What bones form the floor of brain?
The bottom of the brain sits on the Occipital bone.
