ULTRASTRUCTURAL ANALYSIS OF THE DIGESTIVE GLAND OF THE LOBSTER HOMARUS-GAMMARUS - ROLE OF VARIOUS CELL-TYPES IN DIGESTIVE PROCESSES

An ultra-structural study is realised on the digestive gland of the lobster Homarus gammarus. This work shows the presence of five cellular types, four of them being involved in the digestive processes. One type (E-cell) has embryonic characteristics and differentiate, along digestive cycle, into F-...
