ethmoid bone

The ethmoid bone is one of the bones that makes up the orbit of the eye.

The instrument would be inserted through a hole punched into the ethmoid bone near the nose.

The porous, fragile nature of the ethmoid bone makes it particularly susceptible to fractures.

The Ethmoid bone, lying behind the nose.

The ethmoid bone consists of four parts:

The bone found in superior nasal concha is part of the ethmoid bone.

The man ducked- Michael's hand impacting the base of the nose, breaking it, driving it up and through the ethmoid bone into the brain.

The anterior ethmoidal foramen is a small opening in the ethmoid bone in the skull.

The frontoethmoidal suture is the suture between the ethmoid bone and the frontal bone.

Above and to the back (posterosuperiorly), the bony nasal septum is composed of the perpendicular plate of the ethmoid bone.

Its name lamina papyracea is a literal description, as this part of the ethmoid bone is paper-thin and fractures easily.

The ethmoid bone (from Greek ethmos, "sieve") is a bone in the skull that separates the nasal cavity from the brain.

The shape of the nose is determined by the ethmoid bone and the nasal septum, which consists mostly of cartilage and which separates the nostrils.

Some birds and other migratory animals have deposits of biological magnetite in their ethmoid bones which allow them to sense the direction of the Earth's magnetic field.

The ethmoid sinuses of the ethmoid bone are two of the four paired paranasal sinuses.

Cribriform plate of the ethmoid bone (horizontal lamina or lamina cribrosa ossis ethmoidalis)

The ethmoid bone (or a part of it) is sometimes included, but otherwise considered part of the neurocranium; the same is the case with the sphenoid bone.

The cribriform plate of the ethmoid bone (horizontal lamina) is received into the ethmoidal notch of the frontal bone and roofs in the nasal cavities.

Eight fused cranial bones together form the cranial cavity: the frontal, occipital, sphenoid and ethmoid bones, and two each of the parietal and temporal bones.

These fractures start at the nasofrontal and frontomaxillary sutures and extend posteriorly along the medial wall of the orbit through the nasolacrimal groove and ethmoid bones.

The lamina papyracea (or orbital lamina) is a smooth, oblong bone plate which forms the lateral surface of the labyrinth of the ethmoid bone in the skull.

It passes through the anterior ethmoidal opening as the anterior ethmoidal nerve and enters the cranial cavity just above the cribriform plate of the ethmoid bone.

The former involve the occipital bone, temporal bone, and portions of the sphenoid bone; the latter, superior portions of the sphenoid and ethmoid bones.

The nasal septum is composed of the quadrangular cartilage, the vomer bone (the perpendicular plate of the ethmoid bone), aspects of the premaxilla, and the palatine bones.
