Synapses occur at synaptic cleft (or also called as "synaptic gap"). The location of "synaptic cleft" depends on the types of synapses:axo-dendritic synapse : between axons and dendritesaxo-somatic synapse : between axons and cell bodiesaxo-axonic synapse : between axons and axonsdendro-denritic syanpse : between dendrites and dendrites
What is the role of synaptic potentials in the perception of pain? What kind of reaction might you expect if synaptic potentials were removed?
synaptic cleft.
The cause of synaptic delay is attributed mainly to the time needed for the synaptic vesicles to release neurotransmitter into the synaptic cleft. While it can be considered a combination of binding to the presynaptic membrane (which is relatively a transient process) and subsequent exocytosis of the neurotransmitter, the main factor is release. Additionally, it does take a very short period of time for the neurotransmitter to diffuse across the synaptic cleft and bind to to its receptors on the post-synaptic membrane.
Chemicals that bridge the synaptic gap are called neurotransmitters.
Pruning is the process of eliminating unused synapses in the brain to help it to function more efficiently. Synaptic pruning happens to a great degree in newborns and also in adolescents.

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.
Bipolar occurs at the level of the synaptic junction between neurotransmitters and receptors in the limbic system of the brain.
synaptic potential
synaptic vesicles
Synapses occur between two neurons. Electrical activitiy in the pre-synaptic neuron influences the post-synaptic neuron. There are two types of synapses in the body: Electrical and chemical. Electrical synapses occur in pre and post synaptic neurons that are joined via gap junctions. Currents from action potentials flow across the junction through channels called connexons. This current will depolarize the membrane of the post synaptic neuron to threshold, which will continue the action potential in the cell. Electrical synapses are fast and bidirectional. However, they are mainly found in cardiac and smooth muscles, and not in the mammalian nervous system.Chemical synapses use neurotransmitters. Depolarization occurs in the pre-synaptic neuron and calcium ions rush in. The calcium ions activate neurotransmitter release into the synaptic cleft. The neurotransmitters reach the post-synaptic neuron and cause action potentials to develop.Note: this can go into much more detail

synaptic cleft (also known as "synaptic gap")
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.
