The site where neurons communicate with each other A synapse is a small gap that physically separates neurons Axon terminals of a neuron sending a message (the presynaptic neuron) release neurotransmitters into the synapse The neurotransmitters diffuse to the other side (the postsynaptic side) where they bind to receptors on the postsynaptic neurons, thereby relaying the message
the gap between nerve cells One nerve cell stimulates another one to fire an electric pulse by secreting special chemicals called neurotransmitters into the synapse between the cells
A synapse is one of the points in the nervous system at which a signal passes from one nerve cell to another. the place where nerve cells meet, especially in the brain (synapsis, from , , from synaptein , from syn- ( SYN-) + haptein ). Site of transmission of electric nerve impulses between two nerve cells or between a nerve cell and a gland or muscle cell. At chemical synapses, impulses are transmitted across microscopic spaces via chemical substances called neurotransmitters. In electric synapses, direct communication between nerve cells whose membranes are fused is possible because ions flow between the cells through channels. Electric synapses are found mainly in invertebrates and lower vertebrates; they transmit messages faster than chemical synapses. Chemical transmission seems to have evolved in large, complex vertebrate nervous systems, in which multiple messages must be transmitted over long distances
Communicating cell-cell junction that allows signals to pass from a nerve cell to another cell In a chemical synapse the signals carried by a diffusible neurotransmitter; in an electrical synapse a direct connection is made between the cytoplasms of the two cells via gap junctions
Specialized ending of the neuron axon that is responsible for releasing small packets of neurotransmitters which stimulate the next neuron in the pathway
The area of electrochemical contact between two neurons Synapses can be excitatory (causing an increase in the receiving neuron's activation level) or inhibitory (causing a decrease in the activation level)
a gap between two neurons in the brain across which an impulse is transmitted by diffusion from one neuron across the synapse to another neuron by means of a chemical neurotransmitter
Area where the fine processes of one neuron are in contact with the fine processes of another neuron - electrical impulses are transmitted here from one cell to another
the junction between two neurons (axon-to-dendrite) or between a neuron and a muscle; "nerve impulses cross a synapse through the action of neurotransmitters
A tiny gap between the ends of nerve fibers across which nerve impulses pass from one neuron to another; at the synapse, an impulse causes the release of a neurotransmitter, which diffuses across the gap and triggers an electrical impulse in the next neuron
