Ethmoid bone The ethmoid bone is an anterior cranial bone located between the eyes. It contributes to the medial wall of the orbit, the nasal cavity, and the nasal septum. The ethmoid has three parts: cribriform plate, ethmoidal labyrinth, and perpendicular plate.

Overview Mucosal thickening in the left anterior ethmoid and maxillary sinuses and in the region of the infundibulum. This indicates an ostiomeatal pattern of sinusitis. The sphenoid sinus drains posterior to the superior turbinate into the sphenoethmoid recess through the sphenoid ostium.

Overview Ethmoid sinus. The ethmoid sinuses arise in the ethmoid bone, forming several distinct air cells between the eyes. They are a collection of fluid-filled cells at birth that grow and pneumatize until the age of 12. The ethmoid cells are shaped like pyramids and are divided by thin septa.

Ethmoid Sinusitis Ultimately, mucus that goes through the sinuses will drain to the nose. Sinusitis occurs when mucus backs up in your sinuses and your sinuses become infected. This is usually due to swelling of the nasal passages. Upper respiratory infections or allergies can ultimately lead to ethmoid sinusitis. Other names for sinusitis include rhinosinusitis or nasal congestion. Conditions that affect the structure of the sinuses or the flow of nasal secretions can cause sinusitis.

Mastoiditis From Wikipedia, the free encyclopedia. Mastoiditis is the result of an infection that extends to the air cells of the skull behind the ear. Specifically, it is an inflammation of the mucosal lining of the mastoid antrum and mastoid air cell system inside the mastoid process.The mastoid process is the portion of the temporal bone of the skull that is behind the ear which contains open, air-containing spaces.astoiditis is the result of an infection that extends to the air cells of the skull behind the ear.

The Ethmoid Bone The perpendicular plate is a thin lamina which runs horizontally from the cribriform plate. Inferiorly it attaches to the septal cartilage of the nose and hereby forms part of the nasal septum. The cribriform plate (Latin “cribriform” = perforated) lies within the ethmoidal notch of the frontal bone and forms the roof of the nasal cavity.

What Is Glipizide and Metformin Used For? 1 A sulfonylurea, such as glipizide, helps the pancreas make more insulin. It also helps the cells respond to insulin better. This helps to lower blood sugar and keep it under better control.  Metformin works in several ways. It decreases the amount of sugar (glucose) made by the liver.

- Xiphoid process Definition. It is a small cartilaginous projection of the lower portion of the breastbone or sternum that ranges in size from miniscule to several inches in length. The term “xiphoid” is derived from the Greek word xiphos, meaning straight sword. The tapered piece of bone is also known by the following names: 1  Metasternum.

Xiphoid Process Xiphoid process is a small projection of the lower part of the breastbone or known as the sternum and is made up of cartilage.iphoid process is generally an unsupported structure and unprotected by the ribcage that it is potential for an easy break off. The break in the xiphoid process is particularly potential during the cardiopulmonary resuscitation that extra care is necessary when performing CPR.

Mastoiditis [edit on Wikidata] Mastoiditis is the result of an infection that extends to the air cells of the skull behind the ear. Specifically, it is an inflammation of the mucosal lining of the mastoid antrum and mastoid air cell system inside the mastoid process. The mastoid process is the portion of the temporal bone of the skull that is behind the ear which contains open, air-containing spaces. Mastoiditis is usually caused by untreated acute otitis media (middle ear infection) and used to be a leading cause of child mortality.

- A purist's definition of mastoiditis includes all inflammatory processes of the mastoid air cells of the temporal bone. As the mastoid is contiguous to and an extension of the middle ear cleft, virtually every child or adult with acute otitis media (AOM) or chronic middle ear inflammatory disease has mastoiditis.ther areas of the temporal bone pneumatize similarly, including the petrous apex and the zygomatic root. The antrum, as with the mastoid air cells, is lined with respiratory epithelium that swells when infection is present.

sinus paranasal sinus. An air cavity in a facial bone, either the frontal, maxillary, sphenoid, or ethmoid bones; most paranasal sinuses occur in pairs. The paranasal sinuses are lined with ciliated epithelium that secretes mucus. The sinuses open into the lateral walls of the nasal cavities via small holes. Healthy paranasal sinuses are radiolucent. Synonym: accessory nasal sinus; air sinus; See: illustration.

Xiphoid Process Xiphoid process is a small projection of the lower part of the breastbone or known as the sternum and is made up of cartilage. Xiphoid process is also known as metasternum, xiphisternum and xiphoid cartilage. It is located exactly at the center of the chest below the nipple line in a downward projection at the lowest portion of the rib that connects the sternum.

- Sphenoid sinus. The sphenoid sinuses are a pair of large paranasal sinuses located posterior to the ethmoid sinuses. These paired sinuses develop separately from the nasal capsule of the embryonic nose, often divided by a single vertical intersinus septation.
