You test the ocular reflexes and you find: - a normal bilateral menace response - a normal direct pupillary light reflex (PLR) in the right eye but no consensual PLR in the left eye - no direct PLR in the left eye but a normal consensual PLR in the right eye - a drooping upper eyelid on the left side Where is the lesion most likely to be?

Why would paralysis of the dorsal and ventral buccal branches of the right facial nerve (CNVII) result in marked clinical signs in the horse?

Guttural pouch disease frequently causes neurological signs that can include cranial nerve deficits. This is because five cranial nerves pass through the walls of the guttural pouch of the horse. One of these passes through the lateral compartment and is rarely affected by disease, the other four run through the medial compartment and are commonly affected by disease. Which four cranial nerves run through the medial compartment of the guttural pouch?
