- Catch connective tissue (also called mutable collagenous tissue) is a kind of connective tissue found in echinoderms (such as starfish and sea cucumbers) which can change its mechanical properties in a few seconds or minutes through nervous control rather than by muscular means. Connective tissue, including dermis, tendons and ligaments, is one of four main animal tissues. Usual connective tissue does not change its stiffness except in the slow process of aging. Catch connective tissue, however, shows rapid, large and reversible stiffness changes in response to stimulation under nervous control. This connective tissue is specific to echinoderms in which it works in posture maintenance and mechanical defense with low energy expenditure, and in body fission and autotomy. The stiffness changes of this tissue are due to the changes in the stiffness of extracellular materials. The small amount of muscle cells that are sometimes found scattered in this tissue has little influence on the stiffness-change mechanisms. (en)
- キャッチ結合組織(きゃっちけつごうそしき、英:catch connective tissue)は、動物の組織 (生物学)の一つの結合組織の一種で、棘皮動物にのみ見られるもので、硬さが短時間内に変わる結合組織である。可変結合組織(英:mutable collagenous tissue)と呼ばれることもある。組織の硬さは外界からの刺激に反応して秒から分で変わり、変化は可逆的である(ただし自切の際にはものすごく軟らかくなる不可逆的な変化)。棘皮動物のすべての綱に存在し、姿勢維持や力学的防御に働く。組織の硬さ変化は、結合組織を構成している細胞外成分の硬さ変化によって起こる。 (ja)
