WebCanalele ionice sunt proteine de membrană (membranare) care permit migrarea ionilor prin membranele celulare, și sunt uzual selectiv permeabile. Web61112. Anatomical terminology. [ edit on Wikidata] Endolymph is the fluid contained in the membranous labyrinth of the inner ear. The major cation in endolymph is potassium, with the values of sodium and potassium concentration in the endolymph being 0.91 mM and 154 mM, respectively. [1] It is also called Scarpa's fluid, after Antonio Scarpa.

The idea of the ionic selectivity for potassium channels was that the carbonyl oxygens of the protein backbones of the "selectivity filter" (named by Bertil Hille) could efficiently replace the water molecules that normally shield potassium ions, but that sodium ions were smaller and cannot be completely dehydrated … See more Ion channels are pore-forming membrane proteins that allow ions to pass through the channel pore. Their functions include establishing a resting membrane potential, shaping action potentials and other electrical signals by See more There are two distinctive features of ion channels that differentiate them from other types of ion transporter proteins: 1. The rate of ion transport through the channel is very high (often 10 ions per second or greater). 2. Ions pass through channels down their See more Channels differ with respect to the ion they let pass (for example, Na , K , Cl ), the ways in which they may be regulated, the number of subunits … See more Chemical substances can modulate the activity of ion channels, for example by blocking or activating them. Ion channel blockers See more Because channels underlie the nerve impulse and because "transmitter-activated" channels mediate conduction across the synapses, channels are especially … See more There are over 300 types of ion channels just in the cells of the inner ear. Ion channels may be classified by the nature of their gating, the species of ions passing through those gates, the number of gates (pores), and localization of proteins.
