What is the mnemonic for remembering the cranial nerves?

Remembering cranial nerve names in order of CN I to CN XII: On old Olympus’s towering top a Finn and German viewed some hops. Ooh, ooh, ooh to touch and feel very good velvet. Such heaven!

What cranial nerves are involved in Palpebral reflex?

The sensory fibers for the palpebral and corneal reflexes are in CN V. The three branches of this CN (ophthalmic, maxillary and mandibular) should all be tested. Touching the medial canthus of the eye evaluates the ophthalmic branch. Touching the lateral canthus of the eye evaluates the maxillary branch.

What are the 12 cranial nerves and their function?

This article will explore the functions of the cranial nerves and provide a diagram.

• Diagram.
• I. Olfactory nerve. The olfactory nerve transmits information to the brain regarding a person’s sense of smell.
• II. Optic nerve.
• III. Oculomotor nerve.
• IV. Trochlear nerve.
• V. Trigeminal nerve.
• VI. Abducens nerve.
• VII. Facial nerve.

What are the 12 cranial nerves called?

In higher vertebrates (reptiles, birds, mammals) there are 12 pairs of cranial nerves: olfactory (CN I), optic (CN II), oculomotor (CN III), trochlear (CN IV), trigeminal (CN V), abducent (or abducens; CN VI), facial (CN VII), vestibulocochlear (CN VIII), glossopharyngeal (CN IX), vagus (CN X), accessory (CN XI), and …

Which cranial nerve is responsible for facial sensation?

Sensation on the face is innervated by the trigeminal nerves (V) as are the muscles of mastication, but the muscles of facial expression are innervated mainly by the facial nerve (VII) as is the sensation of taste.

What is the function of this reflex?

Reflexes protect your body from things that can harm it. For example, if you put your hand on a hot stove, a reflex causes you to immediately remove your hand before a “Hey, this is hot!” message even gets to your brain.

When a neurologist asks a patient to smile which cranial nerve is being tested?

Cranial Nerve VII – Facial Nerve Ask the patient to smile, show teeth, close both eyes, puff cheeks, frown, and raise eyebrows. Look for symmetry and strength of facial muscles. See Figure 6.18 for an image of assessing motor function of the facial nerve.

Which cranial nerve is most important?

vagus nerve
Tenth cranial nerve: The tenth cranial nerve, and one of the most important, is the vagus nerve. All twelve of the cranial nerves, the vagus nerve included, emerge from or enter the skull (the cranium), as opposed to the spinal nerves which emerge from the vertebral column.

What are the function of 12 cranial nerves?

Overview of the 12 CNs

How to remember the 12 cranial nerves mnemonics?

To remember whether the nerves are sensory nerves, motor nerves or have both, remember this mnemonic: “Some say marry money but my brother says big brains matter more”. This assigns “s” to sensory, “m” to motor and “b” to both in the order of the cranial nerves.

Can a person be born with a deviation of the uvula?

Also, sometimes people are born with a congenital deviation of the uvula, and this may not cause any symptoms or difficulties in these individuals. The 9th cranial nerve is referred to as the Glosopharyngeal nerve and the 10th cranial nerve is called the Vagus nerve.

What causes the uvula to deviate from the palate?

The infection or compression of these nerves may cause uvular deviation or it may occur during a stroke, when the tongue, the palate and the pharynx are deviated along with the uvula.

How are the cranial nerves and gag reflux related?

Both these nerves are responsible for raising the soft palate of the mouth and also the gag reflux which is a protective mechanism that prevents food or liquids from traveling into the lungs when they are swallowed. As both these cranial nerves contribute to these functions, they are tested together.
