Ampullae of Lorenzini - Wikipedia
Ampullae of Lorenzini, found in several basal groups of fishes, are jelly-filled canals connecting pores in the skin to sensory bulbs. They detect small differences in electric potential between their two ends.
Ampullae of Lorenzini - Science and the Sea
2011年5月1日 · Most sharks have keen senses that allow them to track prey, predators, and mates at varying distances. At close range, they also rely on a network of sensors known as ampullae of Lorenzini, named for the Italian scientist …
Ampulla - Wikipedia
An ampulla (/ æmˈpʊlə, - ˈpʌl -/; [1] pl.: ampullae) was, in Ancient Rome, a small round vessel, usually made of glass and with two handles, used for sacred purposes.
Ampullae of Lorenzini - an overview | ScienceDirect Topics
The ampullae of Lorenzini (Figures 3.15 and 3.37) are modified parts of the lateral line system (see later) and primarily sensitive to electrical fields (they can help a shark sense prey by detecting the electrical fields generated by activities of the prey). They form a series of tube-like structures just beneath and parallel to the skin.
Ampullae of Lorenzini - an overview | ScienceDirect Topics
The ampullae of Lorenzini are defined here as ampullary sense organs that project to a dorsal octavolateral nucleus in the medulla oblongata and are excited by cathodal stimuli. With this definition, the organs of Lorenzini include the electroreceptive organs in nonteleost fishes and the ampullary organs in amphibians.
Ampulla of Lorenzini | anatomy | Britannica
…have distinctive sense organs, called ampullae of Lorenzini, that are highly sensitive to cooling. These organs consist of small capsules within the animal’s head that have canals ending at the skin surface. The capsules and the canals are filled with a jellylike substance, and the sensory-receptor cells are situated within… Read More

Molecular basis of ancestral vertebrate electroreception | Nature
2017年3月6日 · Elasmobranch fishes, including sharks, rays, and skates, use specialized electrosensory organs called ampullae of Lorenzini to detect extremely small changes in environmental electric fields.
Proton conductivity in ampullae of Lorenzini jelly - Science
2016年5月13日 · In 1678, Stefano Lorenzini first described a network of organs of unknown function in the torpedo ray—the ampullae of Lorenzini (AoL). An individual ampulla consists of a pore on the skin that is open to the environment, a canal containing a jelly and leading to an alveolus with a series of electrosensing cells.
