Summary Introduction
To determine:
The difference between the plasma membrane of postsynaptic neuron and presynaptic neuron.
Introduction:
The junction between two neurons, where they communicate with each other is termed as synapses. At the synapse, one neuron sends a signal to another, target, neuron. Most of the synapses are chemical in nature and communicate with each other via chemical messengers. Some synapses are electrical in nature and via these synapses, ions flow directly to the target cells.

Neuromuscular junction, also called myoneural junction, site of chemical communication between a
nerve fibre and a muscle cell. The neuromuscular junction is analogous to the synapse between two
neurons. A nerve fibre divides into many terminal branches; each terminal ends on a region of muscle
fibre called the end plate. Synaptic Cleft is the space between the presynaptic terminal and
postsynaptic cell. It is roughly the size of 30 nm. The synaptic cleft allows the neurotransmitters to
diffuse and reach the other side of the synapse or the neuromuscular junction. It also contains
enzymes for the degradation of the excess or extra neurotransmitters. Embedded in the end plate are
thousands of receptors, which are long protein molecules that form channels through the membrane.
Upon stimulation by a nerve impulse, the terminal releases the chemical neurotransmitter
acetylcholine from synaptic vesicles. Acetylcholine then binds to the receptors, the channels open, and
sodium ions flow into…
How one action potential triggers another; how the continuous conduction seen in unmyelinated nerve fibers result from a chain reaction of action potentials; and what normally prevents the signal from traveling backward to the neurosoma.
At __________ synapses, neurotransmitters hyperpolarize the membrane, by making it more permeable to K+ or moving membrane potential away from threshold (hyperpolarizing), and making generation of an action potential less likely; these are inhibitory postsynaptic potentials (EPSPs).
