The lateral line, also called the lateral line organ (LLO), is a system of sensory organs found in fish, used to detect movement, vibration, and pressure gradients in the surrounding water. The sensory ability is achieved via modified epithelial cells , known as hair cells , which respond to displacement caused by motion and transduce these ...
An artificial lateral line is an artificial biomimetic array of distinct mechanosensory transducers that, similarly, permits the formation of a spatial-temporal image of the sources in immediate vicinity based on hydrodynamic signatures; the purpose is to assist in obstacle avoidance and object tracking. [1]
The lateral line is clearly visible as a line of receptors running along the side of this Atlantic cod. The lateral line is a sense organ used to detect movement and vibration in the surrounding water. For example, fish can use their lateral line system to follow the vortices produced by fleeing prey. In most species, it consists of a line of ...
English: The lateral line mechanoreception system in fishes works even though the mass of motion signals generated by a fish's own muscles far outweighs the small signals of interest. Commands from the brain to the lateral line via efferent nerves copy the commands to the swimming muscles, suppressing "noise" from swimming movements to reveal ...
This sense is common in aquatic animals, the most cited example being the lateral line system, the array of hydrodynamic receptors found in fish and aquatic amphibians. [4] Arthropods (including crayfish and lobsters) and some mammals (including pinnipeds and manatees) can use sensory hairs to detect water movements. Systems that detect ...
Fish have a lateral line system that detects pressure fluctuations in the water. Such pressure is non-detectable in air, but grooves for the lateral line sense organs were found on the skull of early tetrapods, suggesting either an aquatic or largely aquatic habitat.
In geometry, the Euler line, named after Leonhard Euler (/ ˈ ɔɪ l ər / OY-lər), is a line determined from any triangle that is not equilateral.It is a central line of the triangle, and it passes through several important points determined from the triangle, including the orthocenter, the circumcenter, the centroid, the Exeter point and the center of the nine-point circle of the triangle.
The Penrose triangle, also known as the Penrose tribar, the impossible tribar, [1] or the impossible triangle, [2] is a triangular impossible object, an optical illusion consisting of an object which can be depicted in a perspective drawing.
