Myogenic — contraction refers to a myocyte contraction that originates from a property of the myocyte itself. I.e. the contraction is initiated by the cell itself, not an outside occurrence or stimulus such as nerve innervation. Mechanisms Unstable Membrane … Wikipedia
Myogenic contraction — refers to a contraction initiated by the myocyte cell itself instead of an outside occurrence or stimulus such as nerve innervation. Contents 1 Mechanisms 1.1 Unstable Membrane Potentials 1.1.1 Slow wave potentials … Wikipedia
Slow wave potential — In neurobiology, a slow wave potential is a depolarization in a myocyte cell which does not cause a contraction or action potential. Slow wave potentials are unstable resting membrane potentials that continuously cycle through depolarization and… … Wikipedia

Action potential — In physiology, an action potential is a short lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory. Action potentials occur in several types of animal cells, called… … Wikipedia
End-plate potential — Miniature end plate potentials and end plate spikes recorded from muscle fiber End plate potentials (EPPs) (sometimes called end plate spikes ) are the depolarizations of skeletal muscle fibers caused by neurotransmitters binding to the… … Wikipedia
Nonsynaptic plasticity — Brain connectivity network Nonsynaptic plasticity is a form of neuroplasticity that involves modification of ion channel function in the axon, dendrites, and cell body that results in specific changes in the integration of EPSPs and IPSPs, thus… … Wikipedia
Bathmotropic — Bathmotropic, (derived from the Greek word Bathmos, meaning step or threshold), refers to modification of the degree of excitability, (threshold of excitation), of musculature in general, and of heart musculature specifically. It is used… … Wikipedia
