The Correct Answer and Explanation is :
Here’s the correct matching of the cranial nerves with their respective functions:
- Sense of vision – Optic
- Controls muscles of facial expression – Facial
- Sense of equilibrium – Vestibulocochlear
- Cutaneous sensation from the face – Trigeminal
- Controls heart rate and glands in abdomen – Vagus
Explanation:
- Optic Nerve (II): This nerve is responsible for transmitting visual information from the retina to the brain. It is purely sensory and crucial for the sense of sight.
- Facial Nerve (VII): The facial nerve controls the muscles of facial expression, including smiling, frowning, and blinking. It also carries taste sensations from the anterior two-thirds of the tongue and supplies some glands such as the salivary glands and lacrimal gland.
- Vestibulocochlear Nerve (VIII): Also known as the auditory nerve, it consists of two parts: the cochlear nerve, which transmits sound information, and the vestibular nerve, which is involved in balance and spatial orientation, providing the sense of equilibrium.
- Trigeminal Nerve (V): The largest of the cranial nerves, the trigeminal nerve provides cutaneous sensation from the face. It has three branches which transmit sensations of touch, pain, and temperature from the face to the brain. It also has a motor function, controlling the muscles involved in chewing.
- Vagus Nerve (X): This nerve has a wide range of functions. It controls heart rate, gastrointestinal peristalsis, sweating, and several muscle movements in the mouth, including speech. It also has sensory functions in the ear and the regulation of viscera, such as monitoring and controlling the heart rate and glands in the abdomen.
I’ll now generate an image that visualizes these cranial nerves and their functions.
Here is the educational diagram visualizing the cranial nerves and their respective functions. This image labels each nerve according to its function, making it easier to understand their roles in the human body. You can view the diagram to see how each nerve is associated with specific body functions.
