Synapse is located, where two neurons meet each other. One cubic cm of brain cortex have about one billion synapses, probably.

What are the reaction that having a great time leaping across synapses?
There are no reactions, the end of a nerve produces a gas that goes across the synapses and creates the electrical impulse on the other side of the synapses and continues the message!
What are electrical junctions in the human body?
Electrical junctions in the human body are where the axons of nerves (singly called neurons) send a chemical to the dendrite(s) of nearby neuron(s), said chemical creating a weak electrical current in the next neuron. These neuron to neuron junctions are called, "Synapses".
What neurotransmitter is part of the PNS?
The chemical most commonly found in both pre- and postganglionic synapses in the parasympathetic system is the neurotransmitter acetylcholine.
Functions of synapse?
unidirectional transmissionSignals pass from presynaptic to postsynaptic neurone since: synaptic vesicles are only found in presynaptic neurone and receptors for neurotransmitter are only found in postsynaptic neurone.intterconnection between nerve pathwaysOne neurone may receive signal from many synapses from different presnaptic neurones. This allows a wide range of actions in response to a stimulus.memory and learningNeurones involved are linked by new synapses.
What are neural signals?
Neural Signals are the electrical potential carrying the information to be transmitted between neurons/dendrites. They also initiate chemical stimulation on the synapses to transfer/carry forward the message from/to brain.
Where are electric found?
Electrical synapses are found in the retina.
What is an electrical synapse?
Chemical synapses are much slower to react to stimuli. However chemical synapses transmit a signal with constant strength or even a signal that get stronger. This is called "gain." Electrical synapses are faster but have no "gain," the signal gets weaker as it travels along the synapse to other neurons. Electrical synapses are only used for applications where a reflex must be extremely fast. They are simple and allow for synchronized action. A benefit of electrical synapses is they will transmit signals in both directions. Chemical synapses have many important advantages as well. They are more complex and vary their signal strengths. Their functions are influenced by chemical outputs in the nervous system. Chemical synapses are the most common type.

Which types of electrical signals allow rapid long-distance communication within the nervous system?
Electrical Synapses
The electrical synapses between adjacent myocardial cells are called?
gap junctions
Describe the general structure of a synapse?
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
Are gap junctions chemical synapses?
Gap junctions are connections between cells and some do pass ions from one cell to another cell. Some are chemical, some are electrical synapses ans some are direct connections.
What part of the brain controls how long it takes to rect?
One of the limiting factors on reaction time is the chemical/electrical synapses.
What are gap junctions in cells?
They are connections between animal cells which connects the cytoplasm between the cells; in neurons, they are electrical synapses.
What is the name of the microscopic cells with tiny connecting branches that send messages to your brain?
They are call synapses, there are two types chemical and electrical.
How the nerves transmit signals to the brain?
Nerves use electrical impulses to transmit signals to the brain. The gaps between the nerve endings are called synapses.
Where does synapses take place?
The synapses take place in the spinal cord
