What is the mnemonic for the cranial nerves?

Evaluate responses using AI:

OFF

Answer explanation

A common mnemonic for the cranial nerves is "Oh, Oh, Oh, To Touch And Feel Very Green Vegetables, AH!" This helps remember the order: Olfactory, Optic, Oculomotor, Trochlear, Trigeminal, Abducens, Facial, Vestibulocochlear, Glossopharyngeal, Vagus, Accessory, Hypoglossal.

What types of nerves are associated with the cranial nerves?

Evaluate responses using AI:

OFF

Answer explanation

Cranial nerves are associated with sensory, motor, and mixed types. They can be classified as sensory (e.g., olfactory), motor (e.g., oculomotor), or mixed (e.g., trigeminal), serving various functions in the head and neck.

What is the function of the trigeminal nerve (CN V)?

Evaluate responses using AI:

OFF

Answer explanation

The trigeminal nerve (CN V) is responsible for sensation in the face and motor functions such as biting and chewing. It has three branches: ophthalmic, maxillary, and mandibular, each serving different facial areas.

What are the branches of the maxillary nerve?

Evaluate responses using AI:

OFF

Answer explanation

The maxillary nerve has several branches, including the zygomatic nerve, infraorbital nerve, superior alveolar nerves, and greater palatine nerve, which supply sensation to the mid-facial region and teeth.

What is the pathway of the mandibular nerve?

Evaluate responses using AI:

OFF

Answer explanation

The mandibular nerve, a branch of the trigeminal nerve (V3), exits the skull through the foramen ovale, then divides into anterior and posterior divisions, supplying motor and sensory innervation to the lower jaw and associated structures.

What is the sensory innervation provided by the mandibular nerve?

Evaluate responses using AI:

OFF

Answer explanation

The mandibular nerve provides sensory innervation to the lower jaw, including the skin of the chin, lower lip, and parts of the tongue, as well as the teeth and gums of the lower jaw.
