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.
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.
Where is hypothalamus stored?
The hypothalamus is located in the brain, specifically at the base and is part of the diencephalon. It sits below the thalamus and plays a crucial role in regulating various bodily functions, including hormone production, temperature regulation, and hunger.
Where is the brain lodged in human body?
The brain is located within the cranial cavity, which is a protective structure formed by the bones of the skull. It sits at the top of the central nervous system and is responsible for controlling various bodily functions, thoughts, emotions, and behaviors.
What is pituitary of brain?
The pituitary of the brain sits in a tiny bony space called the sella turcica.
What bony depression of the cranial floor does the pituitary sit?
The pituitary gland sits in the hypophyseal fossa, which is a bony depression on the cranial floor at the base of the brain. It is located in the sphenoid bone, specifically in the sella turcica region.
What is the same of the gland that sits in the sella turcica?
The gland that sits in the sella turcica is called the pituitary gland. It is often referred to as the "master gland" because it produces and regulates hormones that control various bodily functions.
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.
Where does the pituitary gland sit?
The pituitary gland is located at the base of the brain, just below the hypothalamus and behind the bridge of the nose. It is housed within a bony structure called the sella turcica, which protects the 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.
What bones would most likely be involved in surgery to remove a tumor on the pituitary gland?
The sphenoid bone would most likely be involved in surgery to remove a tumor on the pituitary gland. The pituitary gland sits in a bony structure called the sella turcica, which is part of the sphenoid bone at the base of the 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.
What is the site of the sella turcica?
The sella turcica is located on the sphenoid bone, specifically within the body of the sphenoid bone called the "hypophysial fossa" or "pituitary fossa." It is a saddle-shaped depression where the pituitary gland sits within the skull.
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.
