A patient presents with acute unilateral paralysis of the muscles of facial expression, diagnosed as Bell's palsy. Based on the motor pathway of the facial nerve, which of the following statements regarding this condition is/are correct?
The motor fibers causing this paralysis exit the skull base through the stylomastoid foramen.
The affected pathway originates at the motor nucleus of the facial nerve located in the pons.
The patient will experience a complete loss of mastication (chewing) on the affected side.
These motor fibers loop around the trigeminal nucleus in the pons before exiting the brainstem.
The patient will exhibit an inability to close the eye on the affected side.
(OBA) A patient suffers damage to the orbit in a road traffic incident resulting in damage to the third cranial nerve. Which of the following signs will be present?

Pupillary dilatation and a medial strabismus
Pupillary constriction and a lateral strabismus
Pupillary dilatation and a lateral strabismus
(OBA) A 58-year-old woman presents with gradual hearing loss in her right ear. On examination, Rinne test showed air conduction is greater than bone conduction bilaterally. Meanwhile, Weber test revealed sound lateralizes to the left ear. Which of the following is the most likely diagnosis?
Right-sided conductive hearing loss
Left-sided sensorineural hearing loss
Right-sided sensorineural hearing loss
Left-sided conductive hearing loss
(OBA) A patient was diagnosed with brainstem infarct and cranial nerve examination was done. General examination revealed ptosis of left eye. Corneal reflex was intact as he was able to close his eye. Which cranial nerve is most likely affected in his condition?
Trochlear nerve
Oculomotor nerve
Facial nerve
