1. Action potential arrives at synaptic knob
2. This causes Ca+ gates on the presynaptic membrane to open and the influx of Ca+ ions into cell

What are the two types of catecholamines?
alpha receptors make the heart beat faster, the pupils of the eyes dilate, and the muscles contract. The beta receptors have similar effects and also cause the bronchi in the lungs to open up
When the second excitory postsynaptic potential arrives at a single synapse before the effect of the first has disappeared what occurs?
Temporal summation occurs at a single synapse that is activated by a second excitory postsynaptic potential occurring in rapid succession before the first has disappeared.
What is the definition of the word cholinergic?
The word cholingeric deals with biology and neurotransmitters. It means that a nerve can be activated by acetylcholine within the sympathetic and parasympathetic branches of the nervous system.
What does a solenoid pack do on a 1996 Chrysler Town and Country?
The solenoid pack is activated by the transmission computer to control fluid flow in the transmission. That is how the correct gears are selected.
What does dd off light mean on 2000 Honda CR-V?
Are you sure you don't mean OD off light? If so, that means that the overdrive gear in your transmission is not activated. On automatic transmission models there is a button on the end of the shift lever which controls whether the transmission is in overdrive or not. Push in on this button - the light should go out and overdrive will be activated (which will definitely give you better gas mileage).
How is activated carbon effectively used you the treatment of oral poisoning?
Activated carbon will chemically bond with many (poisonous) substances, making them more inert, and enabling them to be passed out of the body fairly harmlessly. It is not a cure-all, but is a very useful addition to first-aid kits for "accidental poisoning".
How are chemically gated channels activated?
Chemically-gated ion channels are receptor membrane proteins that are permeable to specific ions. The 'gating' part of it refers to the channel being open only once activated; which in this case will be by a chemical. An example would be the AMPA glutamate receptor, which has a channel pore that is permeable to sodium ions. Only by binding to glutamate (a neurotransmitter) does the channel allow sodium ions to enter the cell.
Is state change a chemical or physical change?
It's a physical change, because being that the change occurs without any proper chemically activated source state change is natural.
Is the transmission on a Honda Passport electrical?
It is referred to as electrically activated an controlled. It is, however, still a mechanical device with gears and pumps and so on.
How do you know if you have cancer cells in your body?
Cancer cells are a natural occurrence in the human body, so everybody has them. This does not mean they are harmful or active, they only cause cancer in over abundance or if chemically activated somehow.
What is ultimate carcinogen?
Ultimate carcinogen: It is activated and chemically reactive form of a carcinogen or procarcinogen that is capable of direct covalent binding to nucleic acid or protein macromolecules. For example: Benzo(a)pyrene is an ultimate carcinogen.
What is tow haul in automotive?
A selection for strictly towing or hauling if selected or activated the transmission will go into low gear mode and stay in that gear until turned off.
