In neuroanatomy, the maxillary nerve (V 2) is one of the three branches or divisions of the trigeminal nerve, the fifth (CN V) cranial nerve.It comprises the principal functions of sensation from the maxilla, nasal cavity, sinuses, the palate and subsequently that of the mid-face, [1] and is intermediate, both in position and size, between the ophthalmic nerve and the mandibular nerve.
Cochlear nerve fibers (30,000+) each have a most sensitive frequency and respond over a wide range of levels. [17] [18] Simplified, nerve fibers' signals are transported by bushy cells to the binaural areas in the olivary complex, while signal peaks and valleys are noted by stellate cells, and signal timing is extracted by octopus cells. The ...
The cochlea, dedicated to hearing; converting sound pressure patterns from the outer ear into electrochemical impulses which are passed on to the brain via the auditory nerve. The vestibular system, dedicated to balance. The inner ear is found in all vertebrates, with substantial variations in form and function.
The cochlea is a spiral shell-shaped organ responsible for the sense of hearing. ... tympanic branch of the maxillary ... nerve transmits information to ...
Hearing protection is the use of devices designed to prevent noise-induced hearing loss (NIHL), a type of post-lingual hearing impairment. The various means used to prevent hearing loss generally focus on reducing the levels of noise to which people are exposed.
Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), of which there are conventionally considered twelve pairs.Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck, including the special senses of vision, taste, smell, and hearing.
The nerves arise from the trunk of [citation needed] the maxillary nerve (CN V 2) within the pterygopalatine fossa [1]: 496 just before it enters the infraorbital groove. [ citation needed ] The nerve arises as a single trunk which split into 2-3 nerves within the pterygopalatine fossa.
The infraorbital nerve is a branch of the maxillary nerve (CN V 2), itself a branch of the trigeminal nerve (CN V); [2] it may be considered as the terminal branch of the maxillary nerve. [3] It arises from the maxillary nerve in the pterygopalatine fossa. [2]
