WebA nerve impulse is transmitted to another cell at either an electrical or a chemical synapse . At a chemical synapse, neurotransmitter chemicals are released from the presynaptic cell into the synaptic cleft between cells. The chemicals travel across the cleft to the postsynaptic cell and bind to receptors embedded in its membrane. can i make my cell phone number unlisted

Web25 mrt. 2024 · synapse, also called neuronal junction, the site of transmission of electric nerve impulses between two nerve cells (neurons) or between a neuron and a gland or … WebNeurotransmitters are how we communicate between one cell and the next. Synapses between neurons are either excitatory or inhibitory – and that all comes down to the neurotransmitter released. Excitatory neurotransmitters cause the signal to propagate - more action potentials are triggered. Inhibitory signals work to cancel the signal. WebNerve Impulse is transmitted across the Synapse: There are two types of synapses i.e. chemical and electrical, depending upon the nature of the transfer of information across the synapse. Chemical Synapse: The axon terminal divides into many branches and each ends into a synaptic knob. fitzys cafe
