The reproductive organ of the female that secretes fluid for vaginal lubrication during coitus is the vestibular gland. There are four small glands that make up the vestibular gland. There are two small glands on each side of the vaginal orifice. The vaginal orifice is a median slit below and behind the opening of the urethra; its size varies inversely with that of the hymen.
One pair of the small structures constitutes the greater vestibular glands; the other pair constitutes the lesser vestibular glands. The vestibular glands secrete a lubricating substance.

What nerve causes nystagmus?
Nystagmus can be caused by various nerves, but the vestibular nerve is often involved. The vestibular nerve carries sensory information related to balance and spatial orientation from the inner ear to the brain. When there is a disturbance in this nerve's function, it can result in nystagmus, which is characterized by involuntary eye movements.
What nerves combine to form the auditory nerve?
The auditory nerve is formed by the cochlear nerve and the vestibular nerve. The cochlear nerve is responsible for transmitting auditory information from the cochlea to the brain, while the vestibular nerve is responsible for transmitting information related to balance and spatial orientation.
What does selective vestibular neurectomy involve?
Selective vestibular neurectomy involves removing the balance nerve fibers connected to the affected inner ear while preserving hearing function. This surgical procedure is performed to treat vertigo and imbalance caused by Meniere's disease or vestibular schwannoma. By selectively removing these nerve fibers, symptoms of vertigo can be reduced while minimizing hearing loss.
What causes vestibular neuritis?
Vestibular neuritis is typically caused by a viral infection affecting the vestibular nerve in the inner ear. This inflammation of the nerve can disrupt the balance signals sent to the brain, resulting in symptoms like vertigo, dizziness, and nausea.
Which cranial nerve controls both body balance and hearing?
The vestibulocochlear nerve (cranial nerve VIII) is responsible for both hearing (cochlear function) and balance (vestibular function). It carries information from the inner ear to the brain, allowing us to hear and maintain our sense of balance.

Acoustic neuroma most commonly arise from which part of vestibular nerve superior or inferior?
Inf vestibular nerve
What nerves combine to form the auditory nerve?
The auditory nerve is formed by the cochlear nerve and the vestibular nerve. The cochlear nerve is responsible for transmitting auditory information from the cochlea to the brain, while the vestibular nerve is responsible for transmitting information related to balance and spatial orientation.
What is the role of the vestibular nerve?
Balance.
Sites of the maculae?
otoliths and vestibular nerve
Where is the vestibulocochlear nerve situated?
The vestibulocochlear nerve, also known as the cranial nerve VIII, is situated in the inner ear. It consists of two parts: the cochlear nerve which is responsible for hearing, and the vestibular nerve which helps with balance and spatial orientation.
What does selective vestibular neurectomy involve?
Selective vestibular neurectomy involves removing the balance nerve fibers connected to the affected inner ear while preserving hearing function. This surgical procedure is performed to treat vertigo and imbalance caused by Meniere's disease or vestibular schwannoma.

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).
Which cranial nerve controls both body balance and hearing?
The vestibulocochlear nerve (cranial nerve VIII) is responsible for both hearing (cochlear function) and balance (vestibular function). It carries information from the inner ear to the brain, allowing us to hear and maintain our sense of balance.
Which cranial nerve is not involved in taste or smell?
The vestibular (VIII)
What is a vestibular neurectomy?
A vestibular neurectomy is a surgical procedure that involves cutting the vestibular nerve, which is responsible for balance and spatial orientation, to alleviate symptoms of vertigo and dizziness. This procedure is usually considered when other treatments for vestibular disorders, such as medication or physical therapy, have not been effective.
