The amount of calcium ions which come into the axon terminal after an action potential arrives, which depends in part upon the concentration of calcium ions inside and outside the neuron, and also upon the amplitude and shape of the arriving action potential (short duration AP spend less time above the Ca ion gate activation threshold, resulting in fewer gates being opened, therefore less Ca allowed in).
What else can I help you with?
Drugs act at the synapse by?
affecting neurotransmitter release, blocking neurotransmitter reuptake, or binding to neurotransmitter receptors. This alters the signaling between neurons and can have various effects on mood, behavior, and other physiological processes.
The greater the amount of coating the axon the faster the nerve impulse will be transmitted to the synapse?
myelin
What is serotonin turnover?
Turnover is analogous to usage of serotonin; it is the amount that is transmitted across the synapse and re-synthesized to replace the amount of serotonin used.
Can the amount the balloon fills up be controlled by the amount of baking soda?
Can the amount the balloon fills up be controlled by amount of baking soda
Which cranial nerve is responsible for adjusting amount of light entering eye?
The amount of light is actually controlled by the iris sphincter muscle, or the iris. It is controlled by parasympathetic fibers that originate from the Edinger-Westphal nucleus, travel along the oculomotor nerve (CN III), synapse in the ciliary ganglion, and then enter the eye via the short ciliary nerves.
How is the activity of the kidney controlled?
The water regulation in a kidney is controlled by the hypothaelemeus which is located in the brain, and it helps to regulate the amount of water present in a kidney comparative to the water that is released in a normal cycle.
What means of membrane transport is used to release the neurotransmitter into the synaptic cleft?
Neurotransmitters are released from the nerve terminals by a specialized exocytosis process, synaptic vesicles. These are small nearly uniform capsules that join with the cell membrane to expel their contents. Release is both quantal (set amount) and mediated by calcium.
Which country controlled the least amount of land in 1913?
Vatican City controlled the least amount of land in 1913, with an area of around 44 hectares.
How did nations measure wealth under mercantillism?
By the amount of gold and silver they had. By the amount of manufactured goods they controlled According to trade APEX
What civilizations controlled the largest amount of Mesopotamia?
Sumerians
Under mercantilism a nations wealth was defined as?
the amount of gold, silver, and tradable manufactured goods it controlled.
What neurotransmitter does Zoloft affect?
The exact mechanism of Zoloft is unknown, but it is believed to increase the extracellular level of the neurotransmitter serotonin by limiting its reabsorption into the presynaptic cell.
