How Do You Spell EXCITATORY SYNAPSE?

Pronunciation: [ɛksˈɪtətəɹˌi sˈɪnaps] (IPA)

The spelling of "excitatory synapse" can be explained using IPA phonetic transcription: /ɪkˈsɪtətɔri ˈsɪnæps/. The word "excitatory" is pronounced with the stress on the second syllable, beginning with the short "i" sound, followed by the "k" sound, then a schwa, "t", and "t". The word "synapse" is pronounced with the stress on the first syllable, beginning with the "s" sound, followed by a long "i" sound, then "n", "a", "p", and "s". Together, these two words refer to a type of nerve junction that enhances the activity of the receiving neuron.

EXCITATORY SYNAPSE Meaning and Definition

1. An excitatory synapse refers to a specialized junction where two neurons communicate with each other, allowing for the transmission of electrical impulses from one cell to another. It is a particular type of chemical synapse known for its ability to enhance the activity of the post-synaptic neuron. During this process, a neurotransmitter is released from the pre-synaptic neuron, which then binds to specific receptors on the post-synaptic neuron's membrane.

   Excitatory synapses typically utilize a neurotransmitter called glutamate, which is one of the most prevalent excitatory neurotransmitters in the central nervous system. When glutamate is released into the synapse, it binds to ligand-gated ion channels known as glutamate receptors on the post-synaptic neuron. This binding triggers the opening of the ion channels, allowing positively charged ions, such as sodium (Na+) or calcium (Ca2+), to flow into the post-synaptic neuron. This influx of ions generates an excitatory postsynaptic potential (EPSP), which brings the neuron closer to its firing threshold, making it more likely to generate an action potential.

   Excitatory synapses play a crucial role in the overall excitability and functioning of the nervous system. They are responsible for promoting the transmission of nerve impulses, enhancing communication between neurons, and playing a significant role in various cognitive processes, including learning and memory. Dysfunction or imbalance in excitatory synaptic activity can contribute to the development of neurological disorders, such as epilepsy, Alzheimer's disease, or schizophrenia. Therefore, understanding the mechanisms underlying excitatory synapses is essential for unraveling the complexities of the brain and designing effective treatments for related disorders.

Etymology of EXCITATORY SYNAPSE

The word "excitatory synapse" comes from the combination of "excitatory" and "synapse".

The term "excitatory" is derived from the Latin word "excitare", which means "to call forth" or "to rouse". In the context of biology, "excitatory" refers to something that stimulates or activates another element, typically a neuron or a muscle, in order to generate a response.

The term "synapse" comes from the Greek word "synapsis", which means "a joining together" or "a connection". In neuroscience, a synapse is a specialized junction between two nerve cells, where electrical or chemical signals are transmitted from one neuron (the presynaptic neuron) to another (the postsynaptic neuron). Synapses play a crucial role in the communication and information processing within the nervous system.

Plural form of EXCITATORY SYNAPSE is EXCITATORY SYNAPSES
