Ampullae of Lorenzini Science and the Sea

Ampullae of Lorenzini (singular Ampulla) are electroreceptors, sense organs able to detect electric fields. They form a network of mucus-filled pores in the skin of cartilaginous fish (sharks, rays, and chimaeras) and of basal bony fishes such as reedfish, sturgeon, and lungfish. They are associated with and … Visa mer Ampullae were initially described by Marcello Malpighi and later given an exact description by the Italian physician and ichthyologist Stefano Lorenzini in 1679, though their function was unknown. Electrophysiological experiments … Visa mer Ampullae of Lorenzini are physically associated with and evolved from the mechanosensory lateral line organs of early vertebrates. … Visa mer The ampullae detect electric fields in the water, or more precisely the potential difference between the voltage at the skin pore and the voltage at the base of the electroreceptor cells. Visa mer The mucus-like substance inside the tubes may perhaps transduce temperature changes into an electrical signal that the animal may use to detect temperature gradients. Visa mer Each ampulla is a bundle of sensory cells containing multiple nerve fibres in a sensory bulb (the endampulle) in a collagen sheath, … Visa mer Ampullae of Lorenzini also contribute to the ability to receive geomagnetic information.
