The saccule (Latin: sacculus) is a bed of sensory cells in the inner ear that detects linear acceleration and head tilting in the vertical plane, and converts these vibrations into electrical impulses to be interpreted by the brain. When the head moves vertically, the sensory cells of the saccule are moved due to a combination of inertia and ...
Sacculus may refer to: Saccule, a bed of sensory cells in the inner ear; Sacculus (insect antenna anatomy), a sensory organ in the antenna of certain insects; Sacculus (insect genital anatomy), a male genital structure in moths and butterflies; Sacculus, an outer peptidoglycan meshwork that surrounds the bacterial cytoplasm
The macula of utricle (macula acustica utriculi) is a small (2 by 3 mm) thickening lying horizontally on the floor of the utricle where the epithelium contains vestibular hair cells that allow a person to perceive changes in latitudinal acceleration as well as the effects of gravity; it receives the utricular filaments of the acoustic nerve.
The saccule is the smaller sized vestibular sac (the utricle being the other larger size vestibular sac); it is globular in form, and lies in the recessus sphæricus near the opening of the scala vestibuli of the cochlea.
The researchers concluded that when coupled and loaded by the otolithic membrane, hair bundles of the bullfrog sacculus do not oscillate spontaneously but are poised in a dormant regime. However, when stimulated by a sinusoidal pulse, the bundles in the coupled system exhibit an active biphasic response similar to the "twitch" observed in ...
Inner ear. The inner ear (internal ear, auris interna) is the innermost part of the vertebrate ear.In vertebrates, the inner ear is mainly responsible for sound detection and balance. [1]
The vestibular evoked myogenic potential (VEMP or VsEP) is a neurophysiological assessment technique used to determine the function of the otolithic organs (utricle and saccule) of the inner ear.
Human vestibular system of the semicircular canals in the inner ear. The vestibular system, in vertebrates, is a sensory system that creates the sense of balance and spatial orientation for the purpose of coordinating movement with balance.
