Notably, the neural membrane harbours several ion channels which are selectively porous to different ions. For instance, A. Generation of Nerve Impulse: Resting Membrane A nerve impulse is the electric signals that pass along the dendrites to generate a nerve impulse or an action potential. An action potential is due to the movement of ions in and out of the cell. It specifically involves sodium and potassium ions. They are moved in and out of the cell through sodium and potassium channels and sodium-potassium pump. 8.

Vesicles fuse with presynaptic membrane 5.Neurotransmitter is released into the synapse 6. Neurotransmitter binds to receptor proteins on post-synaptic membrane 7. All the nerve fibres carry information in the form of nerve impulse. Nerve impulse is the sum total of physical and chemical disturbances created by a stimulus (electrical, chemical or mechanical) in a neuron or nerve fibre which result in the movement of a wave along the nerve fibre. The inset diagram shows in detail the structures and processes occurring at a single axon terminal and synapse.
