Excitatory postsynaptic potential (EPSP) is produced by depolarization of the postsynaptic cell membrane immediately under the presynaptic ending

Excitatory postsynaptic potential (EPSP)

During this potential, excitatory transmitter opens Na+ or Ca2+ channels in the postsynaptic membrane, producing an inward current & the excitability of the neuron to other stimuli is increased

During Inhibitory postsynaptic potential (IPSP) the excitability of the neuron to other stimuli is decreased

#Unit 7. System Physiology – Animal

Postsynaptic inhibition occurs when an inhibitory transmitter (eg, glycine, GABA) is released from a presynaptic nerve terminal onto the postsynaptic neuron.

The synapse between a motoneuron and a muscle fiber is called the neuromuscular junction

Action potentials are propagated down the motoneuron, depolarize each adjacent region to threshold. Finally, the presynaptic terminal is depolarized, and this depolarization causes voltage-gated Ca2+ channels in the presynaptic membrane to open.
