The semicircular canals are part of the inner ear. They are lined with cilia (microscopic hairs) and filled with a liquid substance, known as endolymph. Every time the head moves, the endolymph

Medicinsk vetenskap vestibular function affecting the semicircular canals and the otolith organs was reflex, and primarily the lateral semicircular canal and the superior vestibular. The location of the semicircular canals of the inner ear in the temporal bone of the skull base is similar to the situation [] in Neanderthals, while the semicircular The ampulla, or base, portion of the three semicircular canals each contain a structure called a crista. These bend in response to angular Engelska. fenestration of the semicircular canals.

this is a key for interpreting lesions, which the CNS interprets as increased activity from the normal canal of the pair This clinical syndrome—superior semicircular canal dehiscence syndrome (SSCD)—was first described by Minor and colleagues in 1998. Patients with SSCD can experience vertigo and oscillopsia (the apparent motion of objects that are known to be stationary) evoked by loud noises and/or by maneuvers that change middle-ear or intracranial pressure (such as coughing, sneezing, or straining).

Dehiscence of the semicircular canals has been described for all three of the canals, namely superior, posterior and lateral. The presence of dehiscence does not mean that an individual will experience any symptoms. Indeed in a large study, 10% of the CT scans of the temporal bone showed dehiscence of the superior semicircular canal in patients who lacked the typical symptoms of the associated
The semicircular canals detect rotational acceleration of the head. When the head is moved the endolymph stays in place relative to the skull and deflects the cupula within which the hair cells are imbedded.

The superior semicircular canal (anterior semicircular canal) is a part of the vestibular system and detects rotations of the head in around the lateral axis, or in other words rotation in the sagittal plane. This occurs, for example, when nodding your head.
El movimiento del fluido dentro de este canal corresponde a la rotación de la cabeza alrededor de un eje vertical (es decir, el cuello), o en otras palabras, la rotación en el plano transversal .
