WebMar 25, 2024 · synapse, also called neuronal junction, 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 a chemical synapse each ending, or terminal, of a nerve fibre … WebFeb 20, 2024 · Neurons are the information processing units of the brain responsible for sending, receiving, and transmitting electrochemical signals throughout the body. Neurons, also known as nerve cells, are essentially the cells that make up the brain and the nervous system. Neurons do not touch each other, but where one neuron comes close to another ...

WebMar 14, 2024 · neurotransmitter release, discharge of chemical substances known as neurotransmitters from a neuron in response to a given stimulus. Neurotransmitter release occurs at synapses, which are the sites of transmission of electric nerve impulses between two neurons or between a neuron and a gland or muscle cell. Each synapse consists of … WebSynaptic transmission is the process by which one neuron communicates with another. Information is passed down the axon of the neuron as an electrical impulse known as action potential. Once the action potential reaches the end of the axon it needs to be transferred to another neuron or tissue. It must cross over the synaptic gap between the presynaptic …

WebSep 27, 2024 · At its simplest, the neuromuscular junction is a type of synapse where neuronal signals from the brain or spinal cord interact with skeletal muscle fibers, … Websynapse: [noun] the point at which a nervous impulse passes from one neuron to another.
WebThis is known as synaptic delay, which is normally about 0.5 msec at every synapse. 3. Fatigability: When synapses are continuously stimulated, after some time, due to exhaustion of neurotransmitter at presynaptic terminals, impulses fail to get conducted. This results in fatigue occurring at level of synapse. Fatigue is a temporary phenomenon.
