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.
Answer:
Rubella
Explanation:
Rubella is a viral disease caused by the infection of Rubella virus. Some signs and symptoms of this disease are as follows -
- A rash which begins on face and later spreads all over the body
- Low fever
- Swollen glands
- Aching joints
- Joint pain
As in the question, the doctor found rash on the body of patient, it was diagonised as Rubella, so the doctor was worried because it can affect the development of her child.
The bones are: malleus (hammer-shaped) , incus (anvil-shaped) and stapes (stirrup-shaped).
They are together known as ear ossicles.
They transmit the vibrations from the eardrum or tympanum to the inner ear.
Yeah!! As it acts in slightly acidic medium i.e., of pH 6.8 so, acidic conditions deactivate amylase enzyme...
Answer:
B) cAMP
Explanation:
Phosphodiesterase is an enzyme that breaks a phosphodiester bond, for example in molecules such as cAMP and cGMP. So, phosphodiestarases are are regulators of signal transduction: regulate the duration of signaling pathway.
Caffeine is central-nervous-system stimulant and the mechanisms of its action usually are: mobilization of intracellular calcium or inhibition of specific phosphodiesterases.
