sweat glands
The most prominent features of ovules of this type are large glands on the outer surface of the integument, occur ring within the sarcotesta.
Molecular evolutionary studies of genes encoding accessory gland proteins also provide evidence for their role in determining reproductive fitness.
In such cases, metacercariae were also found in the digestive gland, gonad and mantle.
The gland contains glycogen deposits, and rough endoplasmic reticulum distended into cisternae with granular material.
A large, irregularly-shaped nucleus containing clumps of condensed chromatin is situated at the end of each gland.
While tumor development is generally solitary, all glands can demonstrate varying numbers of hyperplastic nodules and foci.
Dissemination may occur to multiple organs including the skin, oesophagus, liver, lungs, adrenal glands, pancreas, bowel, kidneys, bone marrow and joints.
Upon entering a snail, the parasite migrates to the heart and digestive gland where it transforms into successive stages of sporocysts.
