The correct Answer is:
To solve the question regarding which cranial nerves are involved in moving the eyes, we will analyze each of the cranial nerves listed and identify their functions. ### Step-by-Step Solution: 1. **Identify the Cranial Nerves**: We have the following cranial nerves to consider: - Optic (Cranial Nerve II) - Oculomotor (Cranial Nerve III) - Trochlear (Cranial Nerve IV) - Trigeminal (Cranial Nerve V) - Abducent (Cranial Nerve VI) 2. **Analyze Each Nerve**: - **Optic Nerve (II)**: This nerve is responsible for vision, not for moving the eyes. **(Not involved)** - **Oculomotor Nerve (III)**: This nerve controls most of the eye's movements, including constriction of the pupil and maintaining an open eyelid. **(Involved)** - **Trochlear Nerve (IV)**: This nerve innervates the superior oblique muscle, which is responsible for downward and lateral eye movement. **(Involved)** - **Trigeminal Nerve (V)**: This nerve is primarily responsible for sensation in the face and motor functions such as biting and chewing. It does not control eye movement. **(Not involved)** - **Abducent Nerve (VI)**: This nerve controls the lateral rectus muscle, which is responsible for moving the eye laterally (outward). **(Involved)** 3. **Select the Involved Nerves**: From the analysis, the cranial nerves involved in moving the eyes are: - Oculomotor (III) - Trochlear (IV) - Abducent (VI) 4. **Conclusion**: The correct selection of cranial nerves that are involved in moving the eyes is **Oculomotor (III), Trochlear (IV), and Abducent (VI)**. Therefore, the answer is **2, 3, and 5**. ### Final Answer: The cranial nerves involved in moving the eyes are **Oculomotor (2), Trochlear (3), and Abducent (5)**.
