What happens when a neurons is above its threshold level?
its depolarized.
A neuron has an altered charge potential?
Depolarized
What was Excitation and Inhibition about?
Excitation and Inhibition occur in the neurons. Excitation is when a neuron becomes depolarized and fires an action potential. Inhibition is when a neuron becomes hyperpolarized preventing it from firing an action potential.
What is the subatomic particles in atom?
electrons ( negative charge), neurons ( no charge or neutral charge), and protons ( positive charge)
What is the negetive charge in the nucleus?
The nucleus of the atom doesn't have a negative charge. It has protons with a positive charge and neurons that don't have a charge.
What is the electric charge does proton have in electron?
A proton has a positive charge which is equal in magnitude but opposite to the charge on an electron, which is negative.
Why the calcium decrease creates convulsion?
Since calcium deficiency causes the neurons to be depolarized easily, and thus repetitive depolarization occurs which will lead to accumulation of acetylcholine in the neuromuscular junction and can cause repetitive muscle contractions which can progress to tetany
What are similar cells?
The only other cells that are similar to neurons in the body are the muscles cells because they both conduct an action potential, obey the All-or-None Law, and can be polarized and depolarized.
A charge difference between the interior of the neuron axon and the exterior exist when the neurons is?
polarized
What is a cell that is more positive than at rest is called?
depolarized
What are the three main states of a neuron?
polarized, depolarized, repolarized
What stimulates the release of neurotransmitters allowing neurons to communicate with each other?
Once action Potential reaches Dendrides of the Neuron, the cell is Depolarized, causing the cell (neuron) to release a chemical signal, known as a nuerotransmitter, from the Pre-synsaptic cleft, where it will bind to recepters on the Post-synaptic cleft.
