Ecdysis: Definition and Links by Encyclopedian.com - All about Ecdysis (199 words) |
 | Ecdysis is the molting[?] of the cuticula[?] in arthropods and related groups (Ecdysozoa). |
| Since the cuticula of these animals is also the skeletal support of the body and is inelastic, it is shed during growth and a new covering of larger dimensions is formed. |
| During the resting period preparation is made by the secretion of fluid from the molting glands of the cellular layer and the loosening of the underpart of the cuticula. |
| Checklist of the Collembola: Some notes on the Ultrastructure of the Cuticula (7777 words) |
| The extracellular cuticula is differentiated from outside to inside into the epicuticula, the procuticula or exocuticula, and the subcuticula or endocuticula. |
| The striations appear to be canals left by protoplasmic filaments that, during the formative stage of the cuticula, extend outward from the epidermal cells. |
| The separation of the old cuticula from the epidermis is accomplished by a moulting liquid formed by the epidermal cells, and/or by special exuvial glands of the epidermis, that dissolves the inner layers of the endocuticula and thus frees the rest of the cuticula from the epidermis (after Snodgrass, 1935). |
