Hirudo medicinalis


Hirudo medicinalis
The medicinal leech. The central nervous system of this annelid contains a relatively small number of large, identifiable cells. This has made the leech, like the molluscs Aplysia and Helisoma, a chosen preparation for studying nervous system mechanisms at the cellular level. Related species of leeches are the organisms of choice for cellular and molecular genetic studies of early development, since the early embryos also contain identifiable cells.
