Biology: Cranial Nerve Questions! Anatomy Quiz

The correct answer is VII, Motor control for facial expression and sensory information related to the face. The facial nerve is responsible for controlling the muscles of facial expression, allowing us to smile, frown, and make various facial expressions. It also carries sensory information from the face, including touch, pain, and temperature. This nerve plays a crucial role in our ability to communicate nonverbally and perceive sensations on our face.

This is a type of sensory nerve that transforms information about vision to the brain. To be specific this supplies information to the retina in the form of ganglion cells.

Motor functions include superiorly uplifting eyelid, superiorly rotating eyeball, construction of pupil on the exposure to light and operating several eye muscles. ONLY MOTOR

This is a type of sensory nerve that contributes in the sense of smell in human being. These basically provide the specific cells that are termed as olfactory epithelium. It carries the information from nasal epithelium to the olfactory center in brain.

Abducens innervates the lateral rectus muscle!

The correct answer is Accessory nerve, motor control of trapezius. The accessory nerve, also known as cranial nerve XI, is responsible for controlling the trapezius muscle. This muscle is located in the upper back and neck and is involved in movements of the head, neck, and shoulders. The accessory nerve plays a crucial role in allowing us to perform actions such as shrugging the shoulders, tilting the head, and rotating the neck.

This motor nerve sends impulses to the midbrain and performs the function of handling the eye muscles and turning the eye.

Muscles of mastication
Sensory for head/neck, sinuses, meninges, & external surface of tympanic membrane

The correct answer is Vestibulocochlear, Motor control of balance. The vestibulocochlear nerve, also known as cranial nerve VIII, is responsible for both hearing (cochlear function) and balance (vestibular function). It carries sensory information from the inner ear to the brain, allowing us to maintain our balance and coordinate our movements. This nerve also helps in detecting the position of our head in space and the direction of our movements, making it crucial for motor control of balance.

Also involved in speech, swallowing, and sensory information from pharynx and larynx.

A sensory nerve which carries sensory information from pharynx (initial portion of throat) and some portion of tongue and palate. The information sent is about temperature, pressure and other related facts.

The correct answer is Hypoglossal, Motor movement of tongue. The hypoglossal nerve is responsible for controlling the movement of the tongue. It innervates the muscles of the tongue, allowing for actions such as swallowing, speaking, and chewing. This nerve plays a crucial role in maintaining proper function and coordination of the tongue muscles, which are necessary for various oral activities.
