Sentences with NEPHRIDIUM (5)
Even here they are still simple tubes; on account of their coiled or looped form they are often called “looped canals.” In most of the Annelids, and many of the Vermalia, we can distinguish three sections in the nephridium—an outer muscular duct, a glandular middle part, and an inner part that opens by a ciliated funnel into the body-cavity.
Goodrich, endorsed by Lankester, led to the opinion that under the general morphological conception of "nephridium" were included two distinct sets of organs, viz.
Bergh (for _Lumbricus_ and _Criodrilus_), whose figures show a derivation of the entire nephridium from mesoblast, and an absence of any connexion between successive nephridia by any continuous band, epiblastic or mesoblastic.
There are thus substantial reasons for believing that the nephridium grows backwards from a funnel as does the coelomoduct.
Essentially, a nephridium is a tube, generally very long and much folded upon itself, composed of a string of cells placed end to end in which the continuous lumen is excavated.
