Based on the test scenario provided, choose what types of cranial nerves were involved and what type of nerve give the options! 1. Test: Without moving the head, the subject follows with the eyes the movement of a pencil in the visual field. What cranial nerve(s) is used AND what type of nerve: THERE ARE FOUR CRANIAL NERVES USED IN THIS TEST (3 ALREADY LISTED BELOW).....WHAT IS THE 4TH ONE? 1. Optic nerve, sensory 2. Oculomotor nerve, motor 3. Trochlear nerve, motor and 4. _________. (REMAINING OPTIONS, CHOOSE ONE: Olfactory nerve, Trigeminal nerve, Abducens nerve, Facial nerve, Vestibulocohlear nerve, Vagus nerve, Accessory nerve, Hypoglossal nerve AND is it Sensory, motor, or mixed?)

Cranial nerves are a set of 12 paired nerves (labeled "CN I-XII") that originate from the brainstem. These nerves innervate and are responsible for controlling the sensory, motor, and autonomic functions in the head and neck. Cranial nerves get their name because they exit or enter the skull through the skull's foramina (openings), which is their pathway to reach their intended organ. This association with the cranium is why the nerves are called "cranial nerves".
The extraocular muscles are a type of skeletal muscle that governs eye movements by three sets of antagonistic muscle pairs: the superior and inferior oblique muscles, lateral and medial rectus muscles, and the superior and inferior rectus muscles.. These extraocular muscles are innervated and controlled by three cranial nerves (CN III, IV, and VI).
