Which feature of a neuron limits the number of action potentials it can produce per second? A)the refractory period b)salutatory conduction c)the threshold d)the length of the axonExplanation / Answer
Vague nerve is the longest cranial nerve. It begin at medulla, which is the base of the brain and innervates through the face, heart, stomach and further down the digestive track.
This, the correct answer is option, A.
A stroke is caused due to no oxygen being supplied to the brain. A stroke usually damages an individual’s muscular movements. The damage caused is due to the spontaneous electrical activity of the neurons. It is triggered by the myofascial triggers.
Thus, the correct answer is option, D.
The sympathetic nervous system is activated when a person is exposed to stress. The sudden release of hormones in response to stress activates norepinephrine and adrenaline. This causes the sympathetic nervous system to increase one’s heart rate and breathing rate in response to fight or flight.
Thus, the correct answer is option, D.
Positron emission tomography (PET) does not record brain activity. PET is used to detect any cancerous tissues or cells in one’s body. The other mentioned above are used for detecting brain activity.
Thus, the correct answer is option, C.
