2022年2月12日 · The crista galli is a thick, midline, smooth triangular process arising from the superior surface of the ethmoid bone, projecting into the anterior cranial fossa. It separates the olfactory bulbs , which lie on either side of it in the olfactory fossae of the cribriform plate .

The crista galli projects upwards from the middle line of the cribriform plate. The long thin posterior border of the crista galli serves for the attachment of the falx cerebri. On either side of the crista galli, the cribriform plate is narrow and deeply grooved.

2023年10月30日 · The cribriform plate (Latin 'cribriform' = perforated) lies within the ethmoidal notch of the frontal bone and forms the roof of the nasal cavity. As the name suggests it comprises numerous openings through which the olfactory fibers from the nasal cavity pass through to the anterior cranial fossa.

2024年3月25日 · Central aspect of the anterior skull base is formed by the cribriform plate of the ethmoid bone separated by crista galli in the midline. The crista galli is a bony ridge and is the landmark for the anterior attachment of the falx cerebri. The cribriform plate (Fig. 3.26.3) is a thin plate of bone with multiple perforations in it, like a sieve ...

The cribriform plate is the horizontal plate of the ethmoid bone that forms the roof of the nasal cavity; it is perforated by many foramina for the passage of the olfactory nerves. On its superior surface is a projection called the crista galli (Dorland, 2011).

2023年1月8日 · The cribriform plate forms the roof of the nasal cavity. It is pierced by numerous olfactory nerve fibres, which gives it a sieve-like structure. Projecting superiorly from the cribriform plate is the crista galli, which provides an attachment point for the falx cerebri (sheet of dura mater that separates the two cerebral hemispheres).

The crista galli (Latin: "crest of the rooster") is a wedge-shaped, vertical, midline upward continuation of the perpendicular plate of the ethmoid bone of the skull, [1] projecting above the cribriform plate [2] into the cranial cavity. It serves as an attachment for the membranes surrounding the brain.

The cribriform plate is the part of the ethmoid bone that consists of two parallel grooves on which the olfactory bulbs sit, separated by a midline triangular process called the crista galli (because of its resemblance to the comb of a rooster). The crista galli …

2024年7月26日 · The cribriform plate (less commonly also called the lamina cribrosa of the ethmoid bone) is a sieve-like structure between the anterior cranial fossa and the nasal cavity. It is a part of ethmoid bone and supports the olfactory bulb, which lies in the olfactory fossa.

The cribriform plate is the part of the ethmoid bone that consists of two parallel grooves on which the olfactory bulbs sit, separated by a midline triangular process called the crista galli (because of its resemblance to the comb of a rooster). The crista galli …
