An otolith ((Ancient Greek: ὠτο-, ōto-ear + λῐ́θος, líthos, a stone) is a small crystal inside a structure in the inner ear; this structure, consisting of three hollow, connected tubes (the vestibular system) allows humans and many animals to sense orientation (up/down) in space, movement in space (including direction), and ...
Within the labyrinth of the inner ear lie collections of calcium crystals known as otoconia or otoliths. In people with BPPV, the otoconia are dislodged from their usual position within the utricle , and over time, migrate into one of the three semicircular canals (the posterior canal is most commonly affected due to its anatomical position).
The otolithic membrane is a fibrous structure located in the vestibular system of the inner ear. It plays a critical role in the brain's interpretation of equilibrium. The membrane serves to determine if the body or the head is tilted, in addition to the linear acceleration of the body. The linear acceleration could be in the horizontal ...
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 ] In mammals , it consists of the bony labyrinth , a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: [ 2 ]
The utricle and saccule are the two otolith organs in the vertebrate inner ear.The word utricle comes from Latin uter ' leather bag '.The utricle and saccule are part of the balancing system (membranous labyrinth) in the vestibule of the bony labyrinth (small oval chamber). [1]
Bags of fentanyl were also found, police say. Circle K is best known for selling gas, beer and snacks, but one 24-hour store in West Florida was also offering bags of meth and fentanyl, according ...
Endolymphatic hydrops is a disorder of the inner ear. It consists of an excessive build-up of the endolymph fluid, which fills the hearing and balance structures of the inner ear. Endolymph fluid, which is partly regulated by the endolymph sac, flows through the inner ear and is critical to the function of all sensory cells in the inner ear.
"The ear canal is actually self-cleaning to some degree. Wax is pushed to the opening of the ear canal by the normal chewing motion of the jaw, and tiny hairs lining the skin help keep wax from ...
