Crista junction model – Daems and Wisse (1966) proposed that cristae are connected to the inner boundary membrane via tubular structures characterized by rather small diameters, termed crista junctions (CJs). In the middle of 1990s these structures were rediscovered by EM tomography, leading to the establishment of this currently widely ...
The ampullary cupula, or cupula, is a structure in the vestibular system, providing the sense of spatial orientation. The cupula is located within the ampullae of each of the three semicircular canals. Part of the crista ampullaris, the cupula has embedded within it hair cells that have several stereocilia associated with each kinocilium. The ...
The crista terminalis (also known as the terminal crest, [citation needed] or crista terminalis of His [1]) is a vertical ridge on the [2]: 56 posterolateral [3] inner surface of the adult right atrium extending between the superior vena cava, and the inferior vena cava.
The crista ampullaris itself is a cone-shaped structure, covered in receptor cells called "hair cells". Covering the crista ampullaris is a gelatinous mass called the cupula. Upon angular acceleration (rotation), the endolymph within the semicircular duct deflects the cupula against the hair cells of the crista ampullaris.
The end of cristae are partially closed by transmembrane protein complexes that bind head to head and link opposing crista membranes in a bottleneck-like fashion. [2] For example, deletion of the junction protein IMMT leads to a reduced inner membrane potential and impaired growth [ 3 ] and to dramatically aberrant inner membrane structures ...
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. At the front part of the cribriform plate, on either side of the crista galli, is a small fissure that is occupied by a process of dura mater.
Abra hopes the structures can help turn things around for some of Brazil’s vulnerable and endangered species, like the Groves’ titi, the Schneider’s marmoset, and the Guiana Spider Monkey.
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.
