The cupula has a small inertia compared to the elastic force (due to the jelly) and the viscous force (due to the endolymph), so T 1 is very small compared to T 2. For humans, the time constants T 1 and T 2 are approximately 5 ms and 20 s, respectively. [5] As a result, for typical head movements, which cover the frequency range of 0.1 Hz and ...
The calcium carbonate that the otolith is composed of is primarily derived from the water. As the otolith grows, new calcium carbonate crystals form. As with any crystal structure, lattice vacancies will exist during crystal formation allowing trace elements from the water to bind with the otolith.
Otoconia are crystals of calcium carbonate and make the otolithic membrane heavier than the structures and fluids surrounding it. [1] The otoconia are composite crystallites that overlie the macular sensory epithelium of the gravity receptors of most vertebrates and are required for optimal stimulus input of linear acceleration and gravity.

The utricle and saccule are part of the balancing system (membranous labyrinth) in the vestibule of the bony labyrinth (small oval chamber). [1] They use small stones and a viscous fluid to stimulate hair cells to detect motion and orientation. The utricle detects linear accelerations and head-tilts in the horizontal plane.
The sense of balance or equilibrioception is the perception of balance and spatial orientation. [1] It helps prevent humans and nonhuman animals from falling over when standing or moving. Equilibrioception is the result of a number of sensory systems working together; the eyes ( visual system ), the inner ears ( vestibular system ), and the ...
In the inner ear, stereocilia are the mechanosensing organelles of hair cells, which respond to fluid motion in numerous types of animals for various functions, including hearing and balance. They are about 10–50 micrometers in length and share some similar features of microvilli . [ 1 ]
Charcot–Leyden crystals are composed of an eosinophilic lysophospholipase binding protein called Galectin-10. They vary in size and may be as large as 50 μm in length. [ 1 ] Charcot–Leyden crystals are slender and pointed at both ends, consisting of a pair of hexagonal pyramids joined at their bases. [ 1 ]
The unit cell is defined as the smallest repeating unit having the full symmetry of the crystal structure. [2] The geometry of the unit cell is defined as a parallelepiped , providing six lattice parameters taken as the lengths of the cell edges ( a , b , c ) and the angles between them (α, β, γ).
