Early development in Dendraster
This summary provides an overview of the key points from the document:
The document discusses early development stages in the sand dollar Dendraster excentricus based on images taken by George von Dassow. It features micrographs that illustrate interesting features of the cleavage stages in this local sea creature.
The document summarizes key anatomical features of several mollusk classes including bivalves, gastropods, cephalopods, and the extinct class trilobites. It includes labeled diagrams of a bivalve anatomy, a nudibranch gastropod, a trilobite, a horseshoe crab, and a squid. Key features highlighted include shells, mantles, siphons, gills, hearts, digestive organs, and reproductive structures.
The document lists the names of various anatomical structures and vessels in a human body, including veins, arteries, muscles, and other internal organs. Some of the structures mentioned are the cava vena, urogenital veins, testes, pelvic veins, femoral artery, femoral vein, sciatic artery, latissimus dorsi muscle, temporalis muscle, and coeliac arteries. Over 50 anatomical names are listed without further description.
Este documento proporciona información sobre los arácnidos. Los arácnidos se diferencian de otros grupos por su adaptación a la vida terrestre y la ausencia de branquias. Presentan un prosoma no segmentado con quelíceros y pedipalpos, y un opistosoma con o sin segmentación. Describe sus sistemas digestivo, excretor, circulatorio y respiratorio, así como sus órganos sensoriales y reproducción. Finalmente, divide a los arácnidos en varios grupos según las características de su prosoma, opist
