_________scan measures brain activity through injecting a radioactive glucose that allows to observe the brain is functioning.
-
MRI
-
CAT
-
FRMI
-
PET
-
EEG
Correct Answer
A. PETExplanation
PET (Positron Emission Tomography) scan is a medical imaging technique that measures brain activity by injecting a radioactive glucose into the body. This radioactive substance allows the observation of how the brain is functioning, as it is taken up by the brain cells. The emitted positrons from the radioactive substance are detected by a scanner, which creates images of the brain activity. MRI (Magnetic Resonance Imaging) and CAT (Computerized Axial Tomography) scans are different imaging techniques that do not involve the use of radioactive substances. FMRI (Functional Magnetic Resonance Imaging) measures brain activity by detecting changes in blood flow, while EEG (Electroencephalography) measures electrical activity in the brain.Rate this question:

-
Understanding what others say
-
Being able to speak
-
Being able to touch his nose
-
Reading
-

-
All-or-none
-
Down an axon
-
Threshold
-
-50 charge
-
Postsynaptic state
Correct Answer
A. Down an axonExplanation
In order for an action potential to occur, a neuron needs to be in a state called "down an axon". This means that the electrical signal is traveling along the axon, away from the cell body towards the axon terminals. This is the phase where the neuron is actively transmitting information to other neurons or muscles. The other options provided, such as "all-or-none", "threshold", "-50 charge", and "postsynaptic state", are not directly related to the specific state of the neuron required for an action potential to occur.Rate this question:

-
Sympathetic
-
Somatic
Correct Answer
A. SomaticExplanation
The somatic nervous system is responsible for controlling voluntary movements in the body. It is a part of the peripheral nervous system, which includes all the nerves outside of the brain and spinal cord. The somatic nervous system allows us to consciously control our muscles and perform actions like walking, talking, and writing. This is in contrast to the autonomic nervous system, which controls involuntary bodily functions like heart rate and digestion. The efferent and afferent nervous systems are subdivisions of the peripheral nervous system and are not specifically related to voluntary movements. The sympathetic nervous system is a part of the autonomic nervous system and is responsible for the body's fight or flight response.Rate this question:
