Summary
| Description |
English: To show the structure of the simplest Turbellaria, the figure represents the left half of a transverse section across the body of the Acoelous planarian Halplodiscus. The mouth (M) is plugged up with a digestive polynuclear mass of cytoplasm and the transitions from this to the stellate scattered central parenchyma (SC) and again from the latter to a firmer peripteral zone (PC) are shown. The outermost layer (EP) is a ciliate epidermis resting on (BM), a basement membrane (dark line), the row of dots beneath this represents the longitudinal muscles (L). |
