Where are electrical synapses found?
Synapse is located, where two neurons meet each other. One cubic cm of brain cortex have about one billion synapses, probably.
Where are electric found?
Electrical synapses are found in the retina.
What is an electrical synapse?
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.
Can excitatory synapses occur anywhere on a dendrite or soma?
True
Describe the general structure of a synapse?
Synapses occur between two neurons. Electrical activitiy in the pre-synaptic neuron influences the post-synaptic neuron. There are two types of synapses in the body: Electrical and chemical. Electrical synapses occur in pre and post synaptic neurons that are joined via gap junctions. Currents from action potentials flow across the junction through channels called connexons. This current will depolarize the membrane of the post synaptic neuron to threshold, which will continue the action potential in the cell. Electrical synapses are fast and bidirectional. However, they are mainly found in cardiac and smooth muscles, and not in the mammalian nervous system.Chemical synapses use neurotransmitters. Depolarization occurs in the pre-synaptic neuron and calcium ions rush in. The calcium ions activate neurotransmitter release into the synaptic cleft. The neurotransmitters reach the post-synaptic neuron and cause action potentials to develop.Note: this can go into much more detail
What are the reaction that having a great time leaping across synapses?
There are no reactions, the end of a nerve produces a gas that goes across the synapses and creates the electrical impulse on the other side of the synapses and continues the message!
Which types of electrical signals allow rapid long-distance communication within the nervous system?
Electrical Synapses
The electrical synapses between adjacent myocardial cells are called?
gap junctions
Where is the synapes located?
A synapse is the junction in between neurones where the original electrical impulses being used to send messages to and from receptor and effector, must be converted into a chemical form and cross a gap between the dendrite and axon terminal. This gap is also commonly known as a synaptic cleft. Now since these synapses are used for neurons to communicate with each other, since neurons cannot communicate directly. Neurones occur all over the body as parts of the nervous system so therefore so too must synapses occur lest the presence of the neurones would be pointless. SUMMARY : Synapses occur throughout the body, wherever there are senses present.
Would you expect synapses to occur in grey matter or in white matter?
Synapses are seen more in grey matter because dendrites meet with axonites in grey matter and dendrite is a part of grey matter.
Are gap junctions chemical synapses?
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.
What part of the brain controls how long it takes to rect?
One of the limiting factors on reaction time is the chemical/electrical synapses.
