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."
The chemical secreted into the gap between neurons at a synapse is known as neurotransmitters. This can be in form of acetylene, serotonin or dopamine among others.
a neurotransmitter
A "synapse" is the gap between neurons in the brain. Since the brain is not hard wired, and the neurons are only connected by a chemical synapse, the brain can be "re-wired" to act in a way it did not before. This is how we are able to learn and perfect new skills.
The term used to describe the gap between two neurons is synapse, or synaptic junction.
The space between the ending of one neuron and the communication with the next neuron is called the synapse, or sometimes it is called the synaptic gap or synaptic cleft. But synapse is the common term.
it can 1. synapse with a ganglionic neuron in the same trunk ganglion, 2. ascend or descend the sympathetic trunk to synapse in another trunk ganglion or 3. pass through the trunk ganglion and emerge from the sympathetic trunk without synapsing The answer: Synapse with a parasympathetic neuron in the same trunk ganglion
Remember that the Schwann cells are made of myelin sheath which insulate the impulse, but also block the sodium ion/potassium ion channels. Therefore there has to be a point where the action potential 'jumps' to, and these are the gaps between the Schwann cells, they are called the Nodes of Ranvier.
The answer is NEUROTRANSMITTER.
By a chemical released by an axon.
A synapse, chemical signals called neurotransmitters cross these gaps, carrying on the signal.
no, synapse. node of ranvier is between axon and dendrites
Synapses
A synapse is the junction or a point of close contact between two neurons.
A neuron is a nerve cell. A synapse is a gap between the sending and receiving neurons, where there are neurotransmitters responsible for transporting chemicals to the receiving neuron. (A neurotransmitter is a chemical messenger.)
A synapse.
Interneurons are multipolar neurons that connects afferent and efferent neurons.
the synapse
Synapse
A Synapse is the space between two neurons or between a neuron and a receptor organ. A single neuron can have a few, or several hundred synapses.
