Biology - Neural Control and Coordination Question with Solution | TestHub
Select the group of cranial nerves which are only motor in function.
Options:
Answer:
Solution:
The cranial nerves can be classified based on their function as sensory, motor, or mixed (both).
The purely motor cranial nerves are:
Oculomotor (III)
Trochlear or Pathetic (IV)
Abducens (VI)
Spinal accessory (XI)
Hypoglossal (XII)
Evaluating the given options:
Abducens, Facial, Spinal accessory: Facial (VII) is a mixed nerve.
Pathetic, Trigeminal, Abducens: Trigeminal (V) is a mixed nerve.
Hypoglossal, Pathetic, Abducens: Hypoglossal (XII), Pathetic (IV), and Abducens (VI) are all purely motor nerves.
Abducens, Facial, Auditory: Facial (VII) is mixed and Auditory (VIII) is purely sensory.
Thus, the group containing only motor nerves is Hypoglossal, Pathetic, and Abducens.
Answer: Hypoglossal, Pathetic, Abducens
