Activity-regulated cytoskeleton-associated protein is a plasticity protein that in humans is encoded by the ARC gene. The gene is believed to derive from a retrotransposon . [ 5 ] The protein is found in the neurons of tetrapods and other animals where it can form virus-like capsids that transport RNA between neurons.
Chevron folding preferentially occurs when the bedding regularly alternates between contrasting competences. [1] Turbidites, characterized by alternating high-competence sandstones and low-competence shales, provide the typical geological setting for chevron folds to occur. Perpetuation of the fold structure is not geometrically limited.
It is one of the planes which, combined with the umbilical plane, defines the four quadrants of the human abdomen. [4] The term parasagittal is used to describe any plane parallel or adjacent to a given sagittal plane. [5] Specific named parasagittal planes include: The midclavicular line crosses through the clavicle. Lateral sternal and ...
A chevron plot is a way of representing protein folding kinetic data in the presence of varying concentrations of denaturant that disrupts the protein's native tertiary structure. The plot is known as "chevron" plot because of the canonical v , or chevron shape observed when the logarithm of the observed relaxation rate is plotted as a function ...
Cephalometric analysis depends on cephalometric radiography to study relationships between bony and soft tissue landmarks and can be used to diagnose facial growth abnormalities prior to treatment, in the middle of treatment to evaluate progress, or at the conclusion of treatment to ascertain that the goals of treatment have been met.

The brow ridges are often not well expressed in human females, as pictured above in a female skull, and are most easily seen in profile. The brow ridge , or supraorbital ridge known as superciliary arch in medicine, is a bony ridge located above the eye sockets of all primates and some other animals.
Chevron of Edmontosaurus in front view. chevron Chevrons, or haemal arches, are bones attached to the underside of caudal vertebrae, forming the ventral surface of the tail. A chevron comprises a left and right part, which are typically fused to each other in a V-shaped fashion, enclosing a large opening that can be seen in front or back view.
The Fenambosy Chevron is one of four chevron-shaped land features on the southwest coast of Madagascar, near the tip of Madagascar, 180 meters (590 ft) high and 5 kilometres (3.1 mi) inland. Chevrons such as Fenambosy have been hypothesized as providing evidence of " megatsunamis " caused by comets or asteroids crashing into Earth . [ 1 ]
