    What is the name and function of Cranial Nerve VI?

    • Vagus, innervation to heart, pharynx, and larynx

    • Accessory, provides motor movement to the trapezius

    • Abducens, motor control for lateral eye movement

    • Glossopharyngeal, Sensory information related to tasted

    Correct Answer
    A. Abducens, motor control for lateral eye movement
    Explanation
    Abducens innervates the lateral rectus muscle!

    Name cranial nerve XI and name ONE function.

    • Accessory nerve, motor control of trapezius

    • Vestibulocochlear, Hearing

    • Vagus, sensory to pharynx

    • Oculomotor, eye movement

    Correct Answer
    A. Accessory nerve, motor control of trapezius
    Explanation
    The correct answer is Accessory nerve, motor control of trapezius. The accessory nerve, also known as cranial nerve XI, is responsible for controlling the trapezius muscle. This muscle is located in the upper back and neck and is involved in movements of the head, neck, and shoulders. The accessory nerve plays a crucial role in allowing us to perform actions such as shrugging the shoulders, tilting the head, and rotating the neck.

    • Trochlear

    • Vagus

    • Glossopharyngeal

    • None of the above

    Correct Answer
    A. Trochlear
    Explanation
    This motor nerve sends impulses to the midbrain and performs the function of handling the eye muscles and turning the eye.

    The Trigeminal Nerve is assigned which number?

    • X

    • IX

    • V

    • VII

    Correct Answer
    A. V
    Explanation
    Muscles of mastication
    Sensory for head/neck, sinuses, meninges, & external surface of tympanic membrane

    Rate this question:

  • 9. 

    Which of the following is Cranial Nerve VIII, and what is ONE function

    • Glossopharyngeal, Sensory information from pharynx

    • Vestibulocochlear, Motor control of balance

    • Trigeminal, Sensory information from Teeth

    • Hypoglossal, Motor control of tongue

    Correct Answer
    A. Vestibulocochlear, Motor control of balance
    Explanation
    The correct answer is Vestibulocochlear, Motor control of balance. The vestibulocochlear nerve, also known as cranial nerve VIII, is responsible for both hearing (cochlear function) and balance (vestibular function). It carries sensory information from the inner ear to the brain, allowing us to maintain our balance and coordinate our movements. This nerve also helps in detecting the position of our head in space and the direction of our movements, making it crucial for motor control of balance.

    • X, Sensory information from heart

    • XII, Motor control of Tongue

    • V, Sensory information from mouth

    Correct Answer
    A. X, Sensory information from heart
    Explanation
    Also involved in speech, swallowing, and sensory information from pharynx and larynx.

    Rate this question:

  • 11. 

    Which of the following is Cranial Nerve IX?

    • Vestibulocochlear

    • Hypoglossal

    • Olfactory

    • Glosspharyngeal

    Correct Answer
    A. Glosspharyngeal
    Explanation
    A sensory nerve which carries sensory information from pharynx (initial portion of throat) and some portion of tongue and palate. The information sent is about temperature, pressure and other related facts.

    • Optic, Vision

    • Hypoglossal, Motor movement of tongue

    • Facial, Sensory from mouth

    Correct Answer
    A. Hypoglossal, Motor movement of tongue
    Explanation
    The correct answer is Hypoglossal, Motor movement of tongue. The hypoglossal nerve is responsible for controlling the movement of the tongue. It innervates the muscles of the tongue, allowing for actions such as swallowing, speaking, and chewing. This nerve plays a crucial role in maintaining proper function and coordination of the tongue muscles, which are necessary for various oral activities.
