What are the divisions of the maxillary nerve?
[1] It has three terminal branches, which in descending order are ophthalmic nerve (V1), maxillary nerve (V2), and mandibular nerve (V3). The ophthalmic and maxillary divisions carry only sensory fibers while the mandibular division carries both sensory and motor fibers.
What is the maxillary division of trigeminal nerve?
The maxillary nerve is the second division of the trigeminal nerve and is also known as the V2 division. This nerve is the middle division of the trigeminal nerve and is attached to the distal convex border of the trigeminal ganglion. The maxillary nerve exits from the cranial cavity through the foramen rotundum.
What are the three major divisions of the trigeminal nerve?
It contains the sensory cell bodies of the 3 branches of the trigeminal nerve (the ophthalmic, mandibular, and maxillary divisions).
How many divisions of trigeminal V are there?
The trigeminal nerve is a mixed cranial nerve that has both sensory and motor functions. There are three divisions of the trigeminal nerve: Ophthalmic division (CN V1 or Va), Maxillary division (CN V2 or Vb), Mandibular division (CN V3 or Vc).

How do you remember the branches of the trigeminal nerve?
A mnemonic for remembering the names of the skull foramina that the division of the trigeminal nerve (CN V) pass through is: Standing Room Only.
What is the name of the third branch of trigeminal nerve?
The three major branches of the trigeminal nerve—the ophthalmic nerve (V1), the maxillary nerve (V2) and the mandibular nerve (V3)—converge on the trigeminal ganglion (also called the semilunar ganglion or gasserian ganglion), located within Meckel’s cave and containing the cell bodies of incoming sensory-nerve fibers.
What is cranial nerve 4 called?
The trochlear nerve is one of 12 sets of cranial nerves. It is part of the autonomic nervous system, which supplies (innervates) many of your organs, including the eyes. This nerve is the fourth set of cranial nerves (CN IV or cranial nerve 4). It is a motor nerve that sends signals from the brain to the muscles.
What are the 12 cranial nerves Mnemonic?
The word order mirrors the numerical order of nerves one through 12: Some say marry money, but my brother says big brains matter more. Some say my mother bought my brother some bad beer, my, my.
Where does the maxillary nerve originate?
The maxillary nerve arises from the anterior edge of the trigeminal ganglion. It courses forward through the lateral dural wall of the cavernous sinus, inferiorly and laterally to the ophthalmic nerve.
What are the 12 cranial nerves mnemonic?
Which is the largest cranial nerve?
The vagus nerve (cranial nerve [CN] X) is the longest cranial nerve in the body, containing both motor and sensory functions in both the afferent and efferent regards.
What is the largest branch of the mandibular nerve?
Buccal Nerve From the Mandibular Nerve
It is also the largest of the three branches of the trigeminal nerve. The sensory root arises from the lateral aspect of the ganglion, with the motor division lying deeper.
What is the smallest nerve?
Trochlear nerve
Trochlear nerve is the smallest cranial nerve. Out of the 12 pairs of cranial nerves, the fourth paired cranial nerve, the trochlear nerve is the smallest of all by virtue of the number of axons.
What is cranial nerve 6 called?
Cranial nerve six (CN VI), also known as the abducens nerve, is one of the nerves responsible for the extraocular motor functions of the eye, along with the oculomotor nerve (CN III) and the trochlear nerve (CN IV).
How do you study the 12 cranial nerves?

Where do the 12 cranial nerves originate?
All the cranial nerves originate from nuclei in the brain. Two of the cranial nerves, the optic nerve and the olfactory nerve, originate from the cerebrum. The accessory nerve has a nucleus in the spinal cord. The rest of the cranial nerves originate from the brain stem.
Which is the shortest nerve?
Which cranial nerve is the smallest?
The trochlear nerve
The trochlear nerve, while the smallest of the cranial nerves, has the longest intracranial course as it is the only nerve to have a dorsal exit from the brainstem. It originates in the midbrain and extends laterally and anteriorly to the superior oblique muscle.
Is the maxillary nerve sensory or motor?
The maxillary nerve is also a sensory branch, and it supplies the territory just below the orbits and above the mouth. This includes the inferior portion of the nasal cavity, the maxillary teeth, and maxillary sinus.
What are the two main sensory branches of the mandibular nerve?
The anterior division of the mandibular nerve gives off one sensory branch (buccal nerve), and three motor branches: masseteric nerve, deep temporal nerves and nerve to lateral pterygoid.
Which is largest nerve in human body?
Sciatic Nerve
Sciatic Nerve and Sciatica. The sciatic nerve is the longest, largest nerve in your body. Your sciatic nerve roots start in your lower back and run down the back of each leg. Sciatica is the pain or discomfort if your sciatic nerve gets compressed or pinched.
What is the thickest nerve in the body?
The sciatic nerve is the longest and thickest (almost finger-width) nerve in the body. It’s actually made up of five nerve roots: two from the lower back region called the lumbar spine and three from the final section of the spine called the sacrum.
What is the 8th cranial nerve called?
