Canalithiasis is the most commonly accepted mechanism, wherein the otoliths that detach from the utricle or saccule and floating freely in the endolymph system of the semicircular canals cause neuronal stimulation.
Laryngocele is a cystic dilation of the laryngeal saccule, which is in communication with the laryngeal lumen.
In addition, little is known on tumor affection of the different parts of the vestibular system, as well as a potential relationship between the function of the individual parts of the vestibular system, i.e., the neuroepithelia of the saccule, utricle, and cristae of the semicircular canals.
[13] Immunohistochemistry approach has shown that the insulin receptor, insulin receptor substrate 1 (IRS1), protein kinase B (PKB) and insulin-sensitive glucose transporter (GLUT4) are expressed in the sensory epithelium of the human saccule, which could explain link between diabetes and balance/hearing disorders.
Specifically, cervical vestibular evoked myogenic potentials (cVEMPs) represent the sternocleidomastoid (SCM) muscle response to sound activation of saccule and signal transmission via the vestibulospinal tract.
[34] found that the sensory epithelium of human saccule expressed insulin-sensitive glucose transporter (GLUT-4), which also exhibited expression of the insulin receptor, insulin receptor substrate 1, and protein kinase B, indicating that those proteins might have a role in mechanism between diabetes and hearing loss.
The sensory organs of the vestibular system are represented by the utricle, the saccule, and the three semicircular canals; they can perceive the gravity vector, the position of the head, and the linear, torsional, and angular accelerations that the head undergoes.
The hyporeflexia of lateral semicircular canal and of the saccule were evaluated on the long-term effects on the CI.
When the treatment area involves the larynx, the secretory cells within the saccule can be affected, leading to poor lubrication of the vocal folds and impairment of vibration and phonation.
This diagnostic method relies on the fact that the utricle and saccule are not only sensitive to linear acceleration, but also to loud sound.
These are the three semicircular canals (superior, posterior and horizontal) that sense rotational head movement or angular acceleration in the yaw, pitch and roll planes, and the two otolith organs (saccule and utricle) that sense linear acceleration, head tilt and gravity.
