statolith


Also found in: Medical, Encyclopedia, Wikipedia.

stat·o·lith

 (stăt′l-ĭth′)
n.
1. One of the small movable calcareous particles in a statocyst.
2. One of the starch grains or other solid particles in a plant cell thought to function in the plant's response to gravity.

statolith

(ˈstætəʊˌlɪθ)
n
1. (Zoology) Also called: otolith any of the granules of calcium carbonate occurring in a statocyst: movement of statoliths, caused by a change in position of the animal, stimulates hair cells, which convey the information to the brain by nerve fibres
2. (Botany) any of various movable inclusions, such as starch grains, that occur in plant cells and are thought to function in geotropic responses
ˌstatoˈlithic adj

stat•o•lith

(ˈstæt l ɪθ)

n.
any of the granules of lime, sand, etc., contained within a statocyst.

Researchers have come to know this by examining a small growth (statolith) in the animal's inner ear, which can be measured like the rings of a tree.
Resolution of growth increments within the statolith micro-structure varies in different parts of statoliths and in different populations and species of coleoid cephalopods.
Tentacular plane slices focused above the statolith and close to the coverslip show a pair of bristle groups side by side, apparently over two groups of lamellate bodies seen end on (Fig.
A strict age validation for ommasterphid squids with the use of statolith and beak measurements has been performed and the results of those experiments indicate that the beak is a reliable material for age estimation (Hu et al., 2015; Liu et al., 2015).
There are two conflicting models that attempt to explain the method of gravity perception in plants: the statolith theory and the gravitational pressure theory.
