Acetylcholine is a neurotransmitter that facilitates impulse transmission at chemical synapses.
Ref: NCERT Class 11 Biology Chapter 18: Neural Control and Coordination Synapse - Types and Neurotransmitters
Electrical synapses allow direct ion flow between neurons through gap junctions, enabling faster communication.
Ref: NCERT Class 11 Biology Chapter 18: Neural Control and Coordination Synapse - Types and Neurotransmitters
Calcium ions (Ca²⁺) enter the synaptic knob and trigger the release of neurotransmitters into the synaptic cleft.
Ref: NCERT Class 11 Biology Chapter 18: Neural Control and Coordination Synapse - Types and Neurotransmitters
At an electrical synapse, neurons are directly connected by gap junctions, allowing rapid impulse transmission.
