Answer:
When a neuron fires and its electric charge travels down the axon, causing neurotransmitters to be released by the neuron's terminal buttons, an <u>action potential</u> occurs.
Explanation:
An action potential, commonly termed as impulse, can be described as messages which are transferred in electrical form. Action potential are caused due to different electric charges. An action potential is generated by a stimulus which causes transfer of sodium ions into the axons resulting in depolarization of the neuron. To overcome this, potassium ion will enter the cell and an action potential will be generated.
The action potential causes release of the neurotransmitters so that signal messages could be transferred.
A host cell infected by a virus will activate the adaptive immune response through white blood cells that are called as lymphocytes.
There are two types of responses through cells: antibody responses and cell mediated immune responses. These responses are occur by different types of classes of white blood cells those are called as B cells and T cells.
These T lymphocytes use chemical messenger to activate other immune system cells so that the adaptive immune system can activate. It detect the infected cells and destroy the cell.
Antibody is a blood protein that is produced in body in response to the specific antigen.
