  1. The biceps brachii reflex tests which nerve roots?

    Answer: C5-C6

    The biceps reflex is mediated by C5-C6 nerve roots via the musculocutaneous nerve, making it useful for diagnosing mid-cervical radiculopathy.

  2. A positive Babinski sign (upgoing plantar response) in an adult indicates:

    Answer: Upper motor neuron lesion involving the corticospinal tract

    An upgoing plantar response (Babinski sign) in adults signifies upper motor neuron pathology affecting the corticospinal tract, such as spinal cord compression or stroke.

  3. Phalen's test is performed by:

    Answer: Holding both wrists in sustained flexion for 60 seconds

    Phalen's test involves sustained bilateral wrist flexion for 60 seconds; reproduction of median nerve paresthesias constitutes a positive result for carpal tunnel syndrome.

  4. The triceps reflex is primarily mediated by which nerve root?

    Answer: C7

    The triceps reflex is mediated by C7 via the radial nerve, and diminished response suggests C7 nerve root compression.

  5. The Romberg test is primarily used to assess:

    Answer: Proprioception and dorsal column (posterior column) integrity

    The Romberg test assesses posterior column integrity; increased sway or falls with eyes closed (positive Romberg) indicates impaired proprioception rather than cerebellar dysfunction.

  6. Which cranial nerve is tested by asking a patient to clench their teeth while the examiner palpates the masseter?

    Answer: CN V (trigeminal nerve)

    The motor division of CN V (trigeminal nerve) innervates the muscles of mastication, including the masseter, temporalis, and pterygoids.

  7. Loss of sensation over the medial forearm, hypothenar eminence, and medial 1.5 fingers most likely indicates compromise of which nerve?

    Answer: Ulnar nerve

    The ulnar nerve supplies the medial forearm, little finger, and medial half of the ring finger; compression commonly occurs at the cubital tunnel (medial elbow).
