How is an impulse (action potential) transmitted from the...

.A synapse is a junction between two neurons that allows the transmission of a nerve impulse from one neuron to another.The action potential is generated in response to a stimulus and travels along the length of the axon, transmitting the nerve impulse. The rise in permeability to Na⁺ is short-lived and is followed by a rise in permeability to K⁺. K⁺ diffuses outside the membrane, restoring the resting potential of the membrane.The new potential developed in the post-synaptic neuron as a result of neurotransmitter binding to specific receptors may be either excitatory or inhibitory.The brain acts as the "command and control system" and controls various functions such as voluntary movements, balance, vital organs, circadian rhythms, endocrine glands and human behavior
