After nervous stimulation stops what prevents ACh in the synaptic cleft from continuing to stimulate contraction?
Acetylcholinesterase destroying the ACH
Serves as the actual go signal for muscle contraction?
in anatomy what destroys acetylcholine(I believe that Ans to the 1st Q: would be) calcium ionsremove the inhibition of the troponin molecules which then triggers muscles contraction.(the 2nd Ans would be) acetylcholinesterase distroys Ach in the synaptic cleft after nervous stimulation stops.
What is the synaptic basis for learning and memory?
The synaptic basis for learning and memory is long-term potentation (LTP), which is an increase in a synapse's firing potential after a brief, rapid stimulation.
What triggers the release of acetylcholine from a synaptic terminal?
Limbic system, a part of nervous system releases Acetyl colin
What is synaptic potential?
synaptic potential
The are sack-like structures found inside the synaptic knob containing chemicals?
synaptic vesicles
What is the small space separating pre and post-synaptic neurons?
synaptic cleft (also known as "synaptic gap")
Where are neurotransmitters produced?
The nervous system is traditionally considered the main producer of neurotransmitters. They are produced in the cyton, or soma; the body of the nerve cell that contains the nucleus. They are then transported to the synaptic vessicles where they wait to be released by an action potential by stimulation.
What are the main differences between between a hormone response and synaptic transmission?
A hormone response is far-reaching and can affect more than one cell or tissue group and can last minutes to hours, even days. Synaptic transmission is strictly locally acting and is over and done with shortly after it begins (i.e, the neurotransmitters are quickly cleared to prevent ongoing stimulation).
What causes calcium ions to enter the synaptic bulb?
The nerve signal arrives at a synaptic knob and causes calcium channels to open. This allows the calcium ions to enter the synaptic knob. Calcium ions entry into the synaptic knob triggers exocytosis of synaptic vesicles, which release acetylcholine into the synaptic cleft.
Is synaptic transmission always from pre to post synaptic?
Yes
What are synaptic gaps?
Synaptic gaps are the spaces between neurons.
