The temporal bone is divided into several main parts/portions 1-3:. squamous part (temporal squama); petrous part (petrous pyramid); tympanic part The frontal nerve is the largest and main branch of the ophthalmic division of the trigeminal nerve (V1).. Gross anatomy. The frontal nerve divides off the ophthalmic division superiorly just before entering the orbit through the superior orbital fissure outside and superolateral to the tendinous ring, where it lies between the lacrimal nerve and the superior ophthalmic vein. Sphenoid bone Body. The body is the most centrally positioned portion.Anteriorly it contributes to the nasal cavity, laterally it builds the medial wall of the optic canal. Superiorly the body forms the sella turcica, the hypophyseal fossa and the dorsum sellae.. They contain the anterior and posterior clinoid processes respectively. The clivus slopes posterior to the body.

The term 'empty sella' was first used by Bush in 1951 to describe a peculiar anatomical condition, observed in 40 of 788 human cadavers, particularly females, characterized by a sella turcica with an incomplete diaphragm sellae that forms only a small peripheral rim, with a pituitary gland not absent, but flattened in such a manner as to form a thin layer of tissue at the bottom ... Pituitary gland or hypophysis cerebri is one of the most important endocrine gland in animal body. This gland lies in the body depression of the sphenoid bone (sella turcica) of skull. You will find the two main part of pituitary gland - adenohypophysis and neurohypophysis. The sella turcica is a saddle shaped cavity which is within the body of the sphenoid and contains the pituitary gland. Its name is from the 'Turkish saddle' which was used by soldiers during the times of the Ottoman Empire and was famous for having four corners.

It is nearly surrounded by bone as it rests in the sella turcica, a depression in the sphenoid bone.The gland is connected to the hypothalamus of the brain by a slender stalk called the ... skeletal, endocrine. Human Organ Systems Diagram - Human Organ Systems Chart - Human anatomy diagrams and charts explained. This diagram depicts Human Organ ... Schematic diagram depicts the blood supply to the adenohypophysis. Blood enters the hypothalamus at the median eminence by way of branches from superior hypophyseal artery. Within the inferior hypothalamus, there is a primary capillary venous plexus. The pituitary gland is located in the pituitary fossa (sella turcica) of the sphenoid bone. Superiorly, the pituitary gland is covered by the circular diaphragma sellae of dura mater. Anteroinferiorly, the gland faces the sphenoid sinus, anterosuperiorly the optic chiasm and laterally the cavernous sinus . Pituitary Hormones. The pituitary gland Pituitary gland The pituitary gland, also known as the hypophysis, is considered the "master endocrine gland" because it releases hormones that regulate the activity of multiple major endocrine organs in the body. The gland sits on the sella turcica, just below the hypothalamus, which is the primary regulator of the pituitary gland.

At the medial of the basisphenoid bone of cow skull anatomy, you will find deep sella turcica (pituitary fossa). The wing of the sella turcica is small but forms the prominent thick pterygoid crest. Two foramina occur on either side of the pterygoid crest. You will find a sizeable rounded foramen orbitorontundum rostrally.

The nasal cavity is a roughly cylindrical, midline airway passage that extends from the nasal ala anteriorly to the choana posteriorly.[1] It is divided in the midline by the nasal septum. On each side, it is flanked by the maxillary sinuses and roofed by the frontal, ethmoid, and sphenoid sinuses in an anterior to posterior fashion.[1] While seemingly simple, sinonasal anatomy is composed of ...

The middle cranial fossa is a paired structure that fuses medially to form the sella turcica. Each side of the middle cranial fossa consists of the sphenoid and one temporal bone. [3] The middle cranial fossa is bound anterolaterally by the lesser wings of the sphenoid and anteromedially by the limbus of the sphenoid. [4]

In the north estern corner of Italy, close to Austria and Slovenia, are the limestone mountains known as the Julian Alps. They have become famous for the exciting trekking and climbing opportunities in what is some of the finest mountain scenery in Europe. Characterised by high mountain lakes, peaceful alpine valleys and rugged limestone peaks, the Julian Alps boast the presence of a large wildlife, most notably the famous "ibex Montasio".

The pituitary gland is a small endocrine organ that controls a multitude of important functions in the body. It is divided into an anterior lobe, intermediate zone, and posterior lobe, all of which are involved in either hormone production or hormone secretion. The pituitary gland is termed the "Master Gland" because it directs other organs and endocrine glands to either suppress or induce ...
