Descriptor transmisión sináptica
Entry term(s) neurotransmisión
transmisión neuronal
Scope note: Comunicación desde una NEURONA hasta un objetivo (neurona, músculo o célula secretora) a través de una SINAPSIS. En la transmisión sináptica química, la neurona presináptica libera un NEUROTRANSMISOR que se difunde a lo largo del espacio sináptico y se une a receptores sinápticos específicos, activándolos. Dichos receptores activados modulan los canales iónicos específicos y/o los sistemas de segundo mensajero en la célula postsináptica. En la transmisión sináptica eléctrica, las señales eléctricas se comunican en forma de flujo de corriente iónica a través de la SINAPSIS ELÉCTRICA.

Scope note: The communication from a NEURON to a target (neuron, muscle, or secretory cell) across a SYNAPSE. In chemical synaptic transmission, the presynaptic neuron releases a NEUROTRANSMITTER that diffuses across the synaptic cleft and binds to specific synaptic receptors, activating them. The activated receptors modulate specific ion channels and/or second-messenger systems in the postsynaptic cell. In electrical synaptic transmission, electrical signals are communicated as an ionic current flow across ELECTRICAL SYNAPSES.
Annotation: differentiate entry term NEURAL TRANSMISSION from NEURAL CONDUCTION; consider also NEURAL INHIBITION; neuromuscular transmission = NEUROMUSCULAR JUNCTION / physiol + SYNAPTIC TRANSMISSION
