The ethmoid bone is an anterior cranial bone located between the eyes. [3] It contributes to the medial wall of the orbit, the nasal cavity, and the nasal septum. [3] The ethmoid has three parts: cribriform plate, ethmoidal labyrinth, and perpendicular plate.
The ethmoid bone is a singular porous cranial bone that makes up the middle area of the neurocranium and forms the midfacial region of the skull. It contributes to the formation of the orbit, nasal cavity, nasal septum and the floor of the anterior cranial fossa.
The ethmoid bone is a small unpaired bone, located in the midline of the anterior cranium – the superior aspect of the skull that encloses and protects the brain. The term ‘ethmoid’ originates from the Greek ‘ethmos’, meaning sieve. This is reflected in its lightweight, spongy structure.
The ethmoid bone is a cube-shaped bone located in the center of the skull between the eyes. It helps form the walls of the eye socket, or orbital cavity, as well as the roof, sides, and interior of the nasal cavity and helps with the sense of smell, protection of the eyeball, and keeping harmful particles from entering through the nose.
The ethmoid is a small unpaired cranial bone that separates the nasal cavity from the brain. The bone got its name from the Greek’ ethmos’, meaning sieve, due to its lightweight and spongy texture.
The ethmoid bone is a small bone with a cuboidal structure that forms the lateral boundaries of the orbit, the anterior cranial fossa superiorly, and the nasal cavities inferiorly. It is relatively light and has a spongy texture.
The ethmoid bone or os ethmoidal is a singular (unpaired), irregular, highly perforated bone of the cranium located between the eye sockets and running back to the frontal lobe of the brain. Ethmos means sieve in Greek which indicates this bone’s many perforations.
The ethmoid bone (also ethmoidal bone, ethmoid, Latin: os ethmoidale) is an unpaired bone of the skull that contributes to the medial wall of the orbit and parts of the nasal cavity. The ethmoid bone includes the cribriform plate with openings that transmit the olfactory nerves (CN I).
Discover the key features, anatomical relations, ossification, and potential variations of the ethmoid bone.
An ethmoid bone is a very particular bone localized between eyeballs and making a significant part of the nasal cavity. By the way, it is the most fragile bone in our body – made almost entirely by thin bony lamellae.
