In the nervous system, a synapse is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target effector cell.
Jul 7, 2024 · synapse, the site of transmission of electric nerve impulses between two nerve cells (neurons) or between a neuron and a gland or muscle cell (effector). A synaptic connection between a neuron and a muscle cell is called a neuromuscular junction.
At the synapse, the firing of an action potential in one neuron—the presynaptic, or sending, neuron—causes the transmission of a signal to another neuron—the postsynaptic, or receiving, neuron—making the postsynaptic neuron either more or less likely to fire its own action potential.
This video discusses synapses, where neurons communicate with target cells. It differentiates between two types of synapses: chemical and electrical. It also explains the role of the synaptic cleft, presynaptic and postsynaptic membranes, and neurotransmitters in this process.
Sep 9, 2009 · The synapse is an intensely studied and highly specialized cellular site yet surprisingly little is known about its origins and evolution. A century of electrophysiological and pharmacological...
Sep 21, 2023 · Neuroscientists now understand that the synapse plays a critical role in a variety of cognitive processes—especially those involved with learning and memory. What is a synapse? The word synapse stems from the Greek words “syn” (together) and “haptein” (to clasp).
Jul 5, 2021 · Synapses are asymmetric intercellular junctions that mediate rapid point-to-point communication between neurons, and thereby connect neurons into circuits ( Fig. 1 A ). Synapses not only transfer information from one neuron to the next, but also process this information during transfer.
Sep 10, 2022 · A synapse is a small gap at the end of a neuron that allows a signal to pass from one neuron to the next. Neurons are cells that transmit information between your brain and other parts of the central nervous system. Synapses are found where neurons connect with other neurons.
Feb 2, 2024 · In psychology, a synapse is the junction between two neurons where information is transmitted from one neuron to another. It consists of the axon terminal of the sending neuron, the synaptic cleft (a small gap), and the dendrite or cell body of the receiving neuron.
Oct 19, 2023 · The juncture between the axon terminals of one neuron and the dendrites of another is known as a synapse. Neurotransmitters are chemicals released by axon terminals which help in carrying signals across synapses. Examples are noradrenaline and epinephrine.
