Inferior nasal concha (medial view) Articulating bony structures include the frontal process of the maxilla anteriorly, the uncinate process of the ethmoid bone and the lacrimal bone anteromedially, and the perpendicular plate of the palatine bone posteromedially.. Osseous development. Laterally, the inferior nasal concha is concave and has no articulations, but it is not the same as the nasal.
  4. Ethmoid bone . The ethmoid bone is an unpaired structure in the midline ( Figure 3.4 ). Superiorly a perforated plate of bone, the cribriform plate, forms the floor of the anterior cranial fossa between the frontal and sphenoid bones. These perforations transmit fibers of the first cranial or olfactory nerve into the nose
  5. g the medial walls of the orbital cavities, the septum of the nose, and the roof and lateral walls of the nasal cavity. It consists of four parts : a horizontal, perforated plate named the cribriform.
  6. The ethmoid bone separates the nasal cavity from the brain, and it articulates with the frontal bone and sphenoid bone.. The skull contains several different sinuses or cavities within the bones of the face and cranium. One of these sinuses is called the ethmoid sinus, and it is located in the ethmoid bone as the name suggests

Each facial bone has its own unique anatomy, characteristics, and functions. The names of the 14 facial bones are: inferior nasal concha (2 of them,) lacrimal bones (2), mandible, maxilla (2. The ethmoid bone and lacrimal bone make up much of the medial wall and the sphenoid bone forms the posterior orbit. At the posterior apex of the orbit is the opening of the optic canal , which allows for passage of the optic nerve from the retina to the brain C. Martin An upward blow to the nose may cause the ethmoid to shatter. In human anatomy, the ethmoid bone is one of the bones that make up the skull.It is situated between the nasal cavity and the brain cavity, and makes up the nasal cavity roof, part of the nasal cavity walls, part of the bony orbits around the eyes, and part of the floor of the cranium

Perpendicular Plate of Ethmoid Bone. The structure indicated is the perpendicular plate of the ethmoid bone. The ethmoid bone is one of the bones in the skull that separates the nasal cavity from the brain. There are three parts of which the ethmoid bone is comprised: Cribriform plate. Ethmoidal labyrinth (one on either side) Perpendicular plate The inferior turbinate is independent of the superior and middle turbinates that extend from the ethmoid bones. The space between each turbinate and the nasal wall is called a meatus. [1] These structures are known classically for aiding warmth of the air from the external environment, as well as possible pathology leading to a common sleep. # Is a separate bone covered by thick mucous membrane. Middle turbinate #Portion of the ethmoid bone. #The concha bullosa is a pneumatized portion of the middle turbinate continuous with ethmoidal air cells 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 ethmoid bone is a fragile coalition of parts. The best way to see all of them is to go back to the skull that was divided in the frontal plane. All of this is the ethmoid bone. This part, the perpendicular plate of the ethmoid, forms a large part of the bony nasal septum. This upward projection is the beginning of the crista galli, which.

Bone window views produce high-resolution images and a good definition of the complete osteomeatal complex and other anatomic details that play a crucial role in sinusitis. The osteomeatal complex provides drainage and ventilation of the frontal, maxillary, and anterior ethmoid air cells(14) The ethmoid bone can be considered in four main parts, all of which we can nicely appreciate in this first anterior view. There are two lateral masses , one on each side, an inferior projection along the midline called the perpendicular plate , and a super projection called the crista galli Cranial bone anatomy can be confusing when we consider the various terms used to describe different areas. The following words are often used incorrectly; this list gives their true meaning: Skull or cranium: all bones of the head, from the top of the head to the hyoid bone (tongue bone). The cranium is the sum of the cranial and facial bones, as well as the bony part of the larynx Ethmoid bone separates the ORBIT from the ETHMOID SINUS. It consists of a horizontal plate, a perpendicular plate, and two lateral labyrinths. Definition (NCI_CDISC) A light and spongy bone that is cubical in shape. This bone is positioned at the anterior part of the cranium, sitting between the two orbits, at the roof of the nose The mandible, or jaw bone, is the only movable bone of the skull and it forms the temporomandibular joint with the temporal bone. The upper teeth are rooted in the two maxillae while the lower teeth are rooted in the mandible and the maxillae also contain paranasal sinuses like the ethmoid, frontal and sphenoid bones of the cranium

However, the bony defect is made much smaller by the contribution of the surrounding bones like lacrimal bone, ethmoid bone, inferior turbinate, and perpendicular plate of the palatine bone.

Forms part of the anterior cranial floor and is a slender bone wedged midsagittally between the orbits (forms the medial wall of the orbits); transversely between the frontal and sphenoid bones; and posterior to the nasal bones thus forming part of the nasal septum and the nasal side walls

The nasal septum is supported by two bones, the ethmoid bone on top and the vomer bone sitting behind the cartilage and ethmoid bone. The tip of the maxillary bone, palatine bone, and other soft tissues support the nasal septum. The mucosal lining (skin covering the septum) shelters and protects the septum, and also helps keep the nose moist. Frontal bone. The frontal bone is one of the thickest bones of the skull. At birth, it is usually paired - right and left- but before the first age of life, the suture separating them (sutura frontalis s. metopica) usually ossifies 1.The occurrence of persistent metopic suture in adult age varies in different countries from nearly 0% to 15%, and it should not be confused with the frontal. Ethmoid bone. The ethmoid bone separates the nasal cavity from the brain. It forms part the perpendicular plate of the osseous nasal septum. It also contains small foramen that allow the olfactory nerve to move from within the skull to the top of the nasal cavity to sample air particles. This part of the ethmoid bone is called the cribriform plate ethmoid ( plural ethmoids ) ( anatomy) A light spongy cubical bone at the root of the nose, forming much of the walls of the nasal cavity and part of those of the orbits and having many perforations through which the olfactory nerves pass to the nose.
