Ear stones in fish.
Oval, stone like structures within the ears of a fish or other vertebrate, which help it to maintain its balance; they are also known as ear stones.
stone-like particles in the macula which aid in our awareness of gravity and movement.
calcareous concretions in the internal ear, especially of teleost fishes (often called ear-stones); frequently used in aging studies
Gravity sensing ear bones in fish. Each fish species has its own unique shape.
small stones found in the otolith organs
Small calcium carbonate crystals located within the maculae of the inner ear's utricle and saccule. The otoliths move in response to head movements, shifting their mass which distorts the hair cell processes. As a result, nerve impulses are generated to the brain for interpretation as head movements for static equilibrium. Ovary (O-vahr-ee) The female gonad, or primary reproductive organ that produces gametes and female sex hormones.
bones formed in the inner ear of fish. The rings or layers can be seen in the entire or sectioned otolith, and counted to determine age.
Calcium carbonate crystals found in the utricle and saccule of the inner ear.
Stone-like particles in the macula which contribute to our awareness of gravity and acceleration, apart from rotation. Saccule: The inner ear area which contains some of the organs that sense position and gravity.
