What is the meaning of Planum sphenoidale?

What is the meaning of Planum sphenoidale?

The planum sphenoidale is a common term for the anterior horizontal part of the superior surface of the body of the sphenoid bone. It is known in the Terminologia Anatomica (2019) as the jugum sphenoideum or sphenoidal yoke 1.

What is the jugum sphenoidale?

Noun. jugum sphenoidale. (anatomy) The structure connecting the two wings of the sphenoid bone.

Where is sphenoid?

An unpaired bone located in the cranium (or skull), the sphenoid bone, also known as the “wasp bone,” is located in the middle and toward the front of the skull, just in front of the occipital bone.

What is olfactory groove meningioma?

The Mount Sinai Health System specializes in diagnosing and treating olfactory groove meningiomas, which are benign growths that form deep in the cranial cavity between the brow and nose in the front part of the base of the skull.

What is sphenoid wing meningioma?

Sphenoid wing meningiomas are slow growing tumors that originate from outer arachnoid meningeal epithelial cells. They are the most common tumor of the intracranial space to spread to the orbit.

What is the weakest part of the skull?

pterion
The pterion is known as the weakest part of the skull. The anterior division of the middle meningeal artery runs underneath the pterion.

What are the two bony structures that make up the nasal septum?

Anatomy The bony portion of the septum includes the perpendicular plate of the ethmoid bone, the vomer, and the maxillary crest, which has contributions from the maxillary and palatine bones. The quadrangular cartilage forms the caudal portion of the septum.

Does sphenoid bone move?

This pressure causes the spheno-basilar junction to move slightly posterior and inferior. On expiration, the spheno-basilar articulation relaxes as the pressure created by the inhaled air is exhaled. This release of pressure causes the spheno-basilar junction to move slightly anterior and superior.

Why is the sphenoid bone so important?

Sphenoid bone has many essential functions. It helps form the base and lateral sides of the skull in combination with the orbital floor. Its many articulations with other bones give the skull rigidity. It is an attachment site for many of the muscles of mastication.

What are the symptoms of an olfactory groove meningioma?

If you have an olfactory groove meningioma, you probably will not experience any symptoms until the tumor grows to a large size. Tumors in this location may cause symptoms such as loss of smell and taste, blurred vision, memory loss, headaches, fatigue, nausea and vomiting, and personality changes.

What causes olfactory groove meningioma?

Symptoms are caused by compression of brain or spinal cord. The tumor has a predilection for certain regions and produces symptoms and signs specific to the tumor’s location. The clinical course of a meningioma characteristically spans a period of years.

How do you know if your meningioma is benign?

If symptoms indicate the possibility of a tumor, a doctor may order a brain scan: an MRI and/or a CT scan. These will allow the doctor to locate the meningioma and determine its size. A biopsy may sometimes be performed. A surgeon removes part or all of the tumor to determine whether it is benign or malignant.

What does the sphenoid bone do?

Sphenoid Bone: The sphenoid bone is a bone in the cranium and skull and is a part of the skeletal system. The sphenoid bone’s functions include protecting the brain and forming a part of the orbits of the eyes. Conditions that can afflict the sphenoid bone include trauma and basilar skull fracture.

Where is sphenoid bone located?

Vincent Chong MD, MBA, MHPE, FRCR, in Skull Base Imaging, 2018 The sphenoid bone is located at the central skull base and is commonly considered the most complex bone in the human body. It forms the major boundary between the intra- and extracranial structures and is a conduit for several cranial nerves.

What is the sphenoid bone?

The sphenoid bone is one of the eight bones that make up the cranium – the superior aspect of the skull that encloses and protects the brain. Its name is derived from the Greek ‘sphenoeides’, to mean wedge-shaped. In this article, we shall look at the anatomy of the sphenoid bone – its location, structure, and clinical significance.
