Which of the following statements are true of sensory pathways? (Read carefully and select all the correct statements.)
A.
Sensory neurons carry impulses from receptors to the CNS.
B.
Sensory tracts include peripheral nerves such as the femoral nerve.
C.
Sensory receptors are different in that each type detects a specific type of change.
D.
Sensory receptors are similar in that they all interpret impulses the same way.
E.
Most of the sensory areas are in the cerebral cortex.
F.
The cranial nerves involved in sensations are part of sensory tracts.
Which of the following statements about the intensity of a nerve response is true?
Select one:
a. A stimulus reaching the threshold level may or may not propagate a nerve impulse.
b. A small voltage shift and a large voltage shift will yield the same nerve impulse as long as the stimulus reaches the threshold level.
c. All stimuli, regardless of the strength, will always generate a nerve impulse.
d. A stimulus resulting in a greater voltage shift will result in a stronger nerve impulse and increased sense of perception in the brain.
