respiration and respiratory systems. Inflation of the lungs in animals stops breathing by a reflex described by the German physiologist Ewald Hering and the Austrian physiologist Josef Breuer. The Hering-Breuer reflex is initiated by lung expansion, which excites stretch receptors in the airways. Stimulation of these receptors, which send signals to the medulla by the vagus nerve, shortens inspiratory times as tidal volume (the...
Calcium flux through NMDARs is thought to be critical in synaptic plasticity, a cellular mechanism for learning and memory. The NMDA receptor is distinct in two ways: first, it is both ligand-gated and voltage-dependent; second, it requires co-activation by two ligands: glutamate and either D-serine or glycine. property of the NMDA receptor is its voltage-dependent activation, a result of ion channel block by extracellular Mg 2+ & Zn 2+ ions. This allows the flow of Na + and small amounts of Ca 2+ ions into the cell and K + out of the cell to be voltage-dependent.
