chorda tympani nerve

This is seen most clearly in patients whose chorda tympani nerve has been damaged by ear surgery.

Through it the chorda tympani nerve enters the tympanic cavity.

Sodium chloride is detected and recognized most by the chorda tympani nerve.

Neuropathy, e.g. following damage to the chorda tympani nerve.

When the greater superficial petrosal and glossopharyngeal nerves are cut, regardless of age, the chorda tympani nerve takes over the space in the terminal field.

The chorda tympani nerve (from the facial nerve via the submandibular ganglion) is secretomotor to the sublingual glands.

These cells are shown to synapse upon the chorda tympani nerves to send their signals to the brain, although some activation of the glossopharyngeal nerve has been found.

The chorda tympani nerve carries its information to the nucleus of the solitary tract, and shares this area with the greater superficial petrosal and glossopharyngeal nerves.

The iter chordæ anterius (canal of Huguier) is placed at the medial end of the petrotympanic fissure; through it the chorda tympani nerve leaves the tympanic cavity.

Lateral pterygoid and the auriculotemporal nerve are lateral relations, the chorda tympani nerve lies medial near its upper end and medial pterygoid is an inferomedial relation.

Before the nerve exits the skull via the stylomastoid foramen and after the nerve to the stapedius muscle has branched off, the facial nerve gives off the chorda tympani nerve.

"Huguier's canal", or the anterior canaliculus of chorda tympani: A canal at the medial end of the petrotympanic fissure, through which the chorda tympani nerve exits the tympanic cavity.

J.N. Langley has shown that there is a period of two to four seconds between when the chorda tympani nerve is stimulated and when the salivary gland associated with this nerve responds.

It is pierced by the foramen ovale and foramen spinosum, and at its posterior part is the sphenoidal spine, which is frequently grooved on its medial surface for the chorda tympani nerve.

Because both the nerve to the stapedius and the chorda tympani nerve (taste) are branches of the facial nerve, patients with Bell's palsy may present with hyperacusis or loss of taste sensation in the anterior 2/3 of the tongue.

It also carries nerve fibers that are not part of the trigeminal nerve, including the chorda tympani nerve of the facial nerve, which provides special sensation (taste) to the anterior 2/3 part of the tongue as well as parasympathetic and sympathetic fibers.

The sensory information from the mucous membranes of the nasopharynx and palate is carried along the greater petrosal nerve, while the chorda tympani nerve (and lingual nerve) carries taste input from the anterior two-thirds of the tongue, floor of mouth, and palate.

The chorda tympani nerve passes through a canal (canal of Huguier), separated from the anterior edge of the petrotympanic fissure by a thin scale of bone and situated on the lateral side of the auditory tube, in the retiring angle between the squama and the petrous portion of the temporal.
