AMPULLAE Meaning and
Definition
-
Ampullae, plural noun, refers to a specialized sensory structure found in certain marine invertebrates, particularly echinoderms such as sea stars and sea cucumbers. These small, bulbous-shaped organs serve as the primary mechanoreceptors for detecting movement and changes in the surrounding water environment. Ampullae function as part of the echinoderm's hydraulic system, which helps regulate body movement and coordination.
Composed of a thin, elongated tube buried within the connective tissue of the organism, each ampulla is connected to a minute opening on the surface via a tiny pore or canal called the madreporite. This pore acts as an inlet for water intake, allowing external water to enter the ampulla. Within the ampulla, specialized receptor cells known as sensory cells are stimulated by the slight shifts in fluid pressure caused by any movement in the surrounding water.
Through these sensory cells, ampullae can detect even the most minuscule vibrations or water currents, allowing the echinoderm to perceive its environment and respond accordingly. This sensory information is then transmitted to the nervous system for interpretation and appropriate reaction, facilitating vital functions such as navigation, feeding, and reproduction.
Overall, ampullae play a crucial role in the sensory perception and coordination of certain marine invertebrates, enabling them to navigate and thrive within their aquatic habitats.
