Web7 jul. 2024 · A nerve impulse is transmitted to another cell at either an electrical or a chemical synapse . How is an impulse transmitted? The nerve impulse is transmitted … 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.
Web14 feb. 2024 · A synapse is a small gap between two neurons, where nerve impulses are relayed by a neurotransmitter from the axon of a presynaptic (sending) neuron to the dendrite of a postsynaptic (receiving) neuron. It is referred to as the synaptic cleft or synaptic gap. During synaptic transmission, the action potential (an electrical impulse) triggers ...
Web28 mei 2024 · A nerve impulse begins when a neuron receives a chemical stimulus. The nerve impulse travels down the axon membrane as an electrical action potential to the axon terminal.
