neurotransmitter (:
Specialized junctions between neurons are called synapses. Synapses allow neurons to communicate with each other by transmitting signals in the form of neurotransmitters. There are two main types of synapses: electrical synapses, where ions flow directly between neurons, and chemical synapses, where neurotransmitters are released to relay the signal.
Neurotransmitters. It's purely chemical.
Gap junctions are connections between cells and some do pass ions from one cell to another cell. Some are chemical, some are electrical synapses ans some are direct connections.
Chemical synapses are much slower to react to stimuli. However chemical synapses transmit a signal with constant strength or even a signal that get stronger. This is called "gain." Electrical synapses are faster but have no "gain," the signal gets weaker as it travels along the synapse to other neurons. Electrical synapses are only used for applications where a reflex must be extremely fast. They are simple and allow for synchronized action. A benefit of electrical synapses is they will transmit signals in both directions. Chemical synapses have many important advantages as well. They are more complex and vary their signal strengths. Their functions are influenced by chemical outputs in the nervous system. Chemical synapses are the most common type.
The chemical used to send messages across synapses is acetylcholine or ACh.
chemical energy
Between the axon terminals and the dendrite for one, there lay the chemical synapse.
Synapses play a critical role in determining reaction time by transmitting electrical or chemical signals between neurons. The efficiency of synaptic transmission can impact the speed at which signals travel through the nervous system, affecting overall reaction time. Stronger or more efficient synapses can lead to faster response times, while weak or impaired synapses may result in slower reaction times.
Neurons meet and communicate with each other at junctions called synapses. At these synapses, they release and receive chemical neurotransmitters to transmit signals from one neuron to another.
There is not just one chemical secreted into synapses (the gaps between neurons); instead, there are many chemicals secreted from the terminal buttons of neurons into the synapses. They are called "neurotransmitters."
Cells in the nervous system communicate to each other across gaps called synapses. At these synapses, signals are passed between neurons using chemical messengers called neurotransmitters. This allows for the transmission of information throughout the nervous system.
