Zoology - Neural Control and Coordination Question with Solution | TestHub

Synapse is the junction through which an impulse is transmitted from one neuron to another. It is formed by the membranes of the pre-synaptic and post-synaptic neurons. The neurons are separated by a synaptic cleft. The$\mathrm{C}{\mathrm{a}}^{2+}$ion helps in transmission of impulse across the synapse.

$\mathrm{N}{\mathrm{a}}^{+}$and${\mathrm{K}}^{+}$ion help in conduction of nerve impulse along a neuron.
