both are electrical movement
Synaptic transmission is chemical, while nerve impulse or axonal transmission is electrical.
Synaptic transmission, also called neurotransmission, refers to the process wherein neurotransmitters are released by a neuron to activate the receptors of another neuron. Communication between two nerve cells is accomplished by synaptic transmission.

prevent transmission across the synaptic cleft
Synaptic vesicles are found in the axon terminals of nerve cells.
the part that facilitates the the transmission of signals is collectively known as the axon but more peculiarly known as the nerve endings.
Nerve impulses are transmitted down the axon and leave the neuron via the terminal bouton at the synaptic interface, releasing neurotransmitters into the synaptic cleft to affect the post-synaptic cell..
Myalin sheath gives insulation to the neurons. They also hasten the nerve conduction by saltatory conduction.
propagation of impulse pre synaptic to post synaptic
1. Nerve impulse reaches synaptic terminal. 2. Synaptic vesicles move to and merge with the presynaptic cell membrane of the motor neuron. 3. Acetylcholine is released into and diffuses across the synaptic cleft. 4. Acetylcholine binds to receptors on the postsynaptic cell membrane of the muscle fiber.
synaptic vesicles
The nerve signal arrives at a synaptic knob and causes calcium channels to open. This allows the calcium ions to enter the synaptic knob. Calcium ions entry into the synaptic knob triggers exocytosis of synaptic vesicles, which release acetylcholine into the synaptic cleft.
