Rhinella lindae Rhinella lindae Rhinella lindae is a species of toad in the family Bufonidae. It is endemic to Colombia and known from its type locality, Murri in the municipality of Frontino, and from , both on the western slope of the Cordillera Occidental, Antioquia Department. The specific name "lindae" honors , an American herpetologist. However, common name Murri beaked toad has been coined for this species. The holotype, an adult female, measures , whereas the paratype male—of unknown maturity status—measures in snout–vent length. The snout is long and acuminate. In the female, tympanic annulus is present but the tympanic membrane is
Membrane stabilizing effect Membrane stabilizing effect Membrane stabilizing effects involve the inhibition or total abolishing of action potentials from being propagated across the membrane. This phenomenon is common in nerve tissues as they are the carrier of impulses from the periphery to the central nervous system. Membrane stabilization is the method through which local anesthetics work. They block the propagation of action potentials across nerve cells, thereby producing a nerve block. Some beta-blockers also possess what is referred to as membrane stabilizing activity (MSA). This effect is similar to the membrane stabilizing activity of sodium channel blockers that represent Class I antiarrhythmics. MSA
