What nerve is not a branch of the trigeminal nerve?
The facial nerve is not a branch of the trigeminal nerve. It is a separate cranial nerve responsible for facial movement and sensation.
What Cranial nerve is equilibrium and hearing?
The cranial nerve responsible for both equilibrium and hearing is the vestibulocochlear nerve (CN VIII). It has two main branches: the vestibular branch, which is associated with balance and equilibrium, and the cochlear branch, which is associated with hearing.
What cranial nerve is used when smelling a flower?
The Olfactory nerve. CN1 Cranial Nerve I, or the first cranial nerve called the Olfactory nerve.
What number cranial nerve is the vagus nerve?
The vagus nerve is the 10th cranial nerve, also known as cranial nerve X.
Which one of the following cranial nerves is NOT involved in either taste?
The optic nerve (cranial nerve II) is not involved in taste, as its primary function is vision. Taste is primarily mediated by the facial nerve (cranial nerve VII), glossopharyngeal nerve (cranial nerve IX), and vagus nerve (cranial nerve X).
In fractures of middle cranial fossa absence of tears is due to lesions in which nerve and why?
The lacrimal gland produces tears in response to parasympathetic stimulation by the greater petrosal nerve. The greater petrosal is nothing more than a renaming of the parasympathetic fibers contributing to the facial nerve after it exits the internal acoustic meatus. It is this opening in the temporal bone that might be damaged in a cranial base fracture, and might also involve a lesion to the greater petrosal nerve. This would also cause an absense of tear formation. If you want to know more, wikipedia has an excellent discussion of the cranial nerves, and here is a link to the facial nerve page: http://en.wikipedia.org/wiki/Facial_nerve Hope that helps!
What nerve passes through the foramen lacerum?
The foramen lacerum is primarily traversed by the greater petrosal nerve, a branch of the facial nerve (CN VII). While no major vessels pass through the foramen itself, the area is adjacent to the internal carotid artery, and the greater petrosal nerve exits the skull through the foramen lacerum, contributing to the formation of the nerve of the pterygoid canal.
What are the contents of the anterior cranial fossa and the middle cranial fossa?

Which cranial nerve controls hearing and body balance?
The cranial nerve that controls hearing and body balance is the vestibulocochlear nerve, also known as cranial nerve VIII. It has two main branches: the cochlear branch, responsible for hearing, and the vestibular branch, responsible for balance and spatial orientation.
What nerve is not a branch of the trigeminal nerve?
The facial nerve is not a branch of the trigeminal nerve. It is a separate cranial nerve responsible for facial movement and sensation.
What Cranial nerve is equilibrium and hearing?
The cranial nerve responsible for both equilibrium and hearing is the vestibulocochlear nerve (CN VIII). It has two main branches: the vestibular branch, which is associated with balance and equilibrium, and the cochlear branch, which is associated with hearing.
What neural injury will the corneal reflex not test for?
The corneal reflex will not test for injuries to the facial nerve (cranial nerve VII) as it primarily assesses the integrity of the trigeminal nerve (cranial nerve V) and the ophthalmic branch of the trigeminal nerve.
Point of which the facial nerve starts to branch?
The facial nerve starts to branch at the geniculate ganglion, which is located just after the nerve exits the internal acoustic meatus of the temporal bone in the skull. From the geniculate ganglion, the facial nerve gives rise to branches that innervate different muscles of the face as well as the lacrimal and salivary glands.
What Can cause irreversible damage to the auditory branch of the eight cranial nerve?
cephalosporins
What cranial nerve is used when smelling a flower?
The Olfactory nerve. CN1 Cranial Nerve I, or the first cranial nerve called the Olfactory nerve.
Which cranial nerve has been damaged when your mouth droops following carotid surgery?
Marginal mandibular branch of the facial nerve.
What number cranial nerve is the vagus nerve?
The vagus nerve is the 10th cranial nerve, also known as cranial nerve X.
