Answer;
-Dendrites receive chemical signals.
-When more excitatory than inhibitory signals are received, the cell depolarizes.
-An action potential is set off and travels through the cell and down the axon.
-The action potential excites the terminal buttons to release their chemicals into the synaptic cleft.
Explanation;
-The electrical signal that passes along the axon and subsequently causes the release of chemicals from the terminal buttons
. Chemical signals (excitatory and inhibitory signals.
-Positive sodium pours into the breach, Action potential propagates along the axon, after firing returns to its slightly negative resting state.
-An action potential can be generated if the amount of excitatory input can raise the membrane potential to -55 mV. This then floods the cell with sodium ions and raises the membrane potential. When it reaches a certain point (about +30 mV), the sodium ion channels close and the potassium ion channels open. This drops the membrane potential back down.
Answer:
The answer is no
Explanation:
Cobalt 60 is a radioactive substance that remains in the environment for up to 6 years, is normally used in medical cancer treatments, but is highly toxic to people.
Exposure of Cobalto 60 for a few minutes can cause death.
The current health authorities are questioning the use of this material in this type of home use, the recommendations are to refrain from using it.
