CRIBROSA Meaning and
Definition
-
Cribrosa is an adjective used in medical terminology to describe a structure or tissue that is characterized by having a sieve-like, porous, or perforated appearance. It is derived from the Latin word "cribrum," meaning sieve or mesh.
In anatomy, the term most commonly refers to the lamina cribrosa, which is a sieve-like structure located at the back of the eye in the optic nerve. The lamina cribrosa forms the openings through which the axons of ganglion cells pass on their way to the brain. Its sieve-like nature allows for the transmission of these axons while providing support and protection to the nerve fibers. Studies have shown that damage or changes in the morphology of the lamina cribrosa can be associated with certain eye conditions, including glaucoma.
Cribrosa may also be used to describe other anatomical structures or tissues that exhibit a similar porous or perforated pattern. For example, the cribriform plate in the skull is a thin, sieve-like bone through which nerve fibers and blood vessels travel to connect the nasal cavity and the brain. Additionally, the cribiform fascia is a connective tissue layer in the neck that contains numerous openings for vessels and nerves.
Overall, cribriform describes a characteristic appearance or structure that resembles a sieve or mesh, with multiple small perforations or pores. It is a term frequently employed in medical and anatomical contexts to denote this particular feature.
