WebSynapsspalt. En nervcell eller neuron är en elektrokemisk celltyp i nervsystemet som är ansvarig för mottagandet och överförandet av nervimpulser. Den kan betraktas som nervsystemets mest grundläggande enhet, även om neuronen inte är den enda celltyp som finns i nervsystemet. Antalet neuroner i hjärnan beräknas uppgå till ungefär ...

Veranschaulichung der Membranströme und … As an action potential (nerve impulse) travels down an axon there is a change in electric polarity across the membrane of the axon. In response to a signal from another neuron, sodium- (Na +) and potassium- (K + )–gated ion channels open and close as the membrane reaches its threshold potential. Na + … See more An action potential occurs when the membrane potential of a specific cell location rapidly rises and falls. This depolarization then causes adjacent locations to similarly depolarize. Action potentials occur in … See more Action potentials result from the presence in a cell's membrane of special types of voltage-gated ion channels. A voltage-gated ion channel is a transmembrane protein that has … See more The course of the action potential can be divided into five parts: the rising phase, the peak phase, the falling phase, the undershoot phase, and the refractory period. During the rising phase the membrane potential depolarizes (becomes more positive). The … See more Chemical synapses In general, action potentials that reach the synaptic knobs cause a neurotransmitter to be released into the synaptic cleft. Neurotransmitters are small molecules that may open ion channels in the postsynaptic cell; … See more Nearly all cell membranes in animals, plants and fungi maintain a voltage difference between the exterior and interior of the cell, called the membrane potential. A typical voltage across an animal cell membrane is −70 mV. This means that the interior of the cell … See more Anatomy of a neuron Several types of cells support an action potential, such as plant cells, muscle cells, and the specialized cells of the heart (in which occurs the See more The action potential generated at the axon hillock propagates as a wave along the axon.
