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.

What is a synapse and how is information transmitted at the synapse?
A synapse is a structure that allows communication between neurons. Information is transmitted across the synapse through the release of neurotransmitters from the presynaptic neuron, which then bind to receptors on the postsynaptic neuron, leading to changes in the postsynaptic neuron's electrical activity.
What location does a neuron transfer an impulse to another cell?
It depends on what the next structure is. If it is another neurone, then it is a synapse. If it is skeletal muscle, then the it is a neuromuscular junction. If it is any other type of muscle, then it is a myoneural junction.
Who named synapse?
The term "synapse" was coined by the English physiologist Charles Scott Sherrington in 1897 to describe the junction between two neurons where electrical or chemical signals are transmitted.
What word is used to describe a gap between two neurones?
The term used to describe the gap between two neurons is synapse, or synaptic junction.

WHICH STRUCTURE IN THE NERVOUS SYSTEM IS MOST LIKE A JOINT IN THE SKELETAL SYSTEM?

What is the junction point between neurons?
A synapse is the junction or a point of close contact between two neurons.
Does the synapse occur between nerve cells?
I wouldn't use the word "occur" since a synapse is a structure, not an event, but yes, it is located between nerve cells, or more specifically, it is where the dendrites of two nerve cells meet.
What is the space between two adjacent nerve cells?
its known as the synapse. Through the synapse is where impulses travel from brain cell to brain cell.
