Only for those groups have scientists almost completely identified all the world's species. Biologists have yet to describe many species of plants, invertebrate animals and lichens. So the number of these species known to science increases substantially every year.
The interglandular tissue is also increased in quantity, and is crowded with large round, oval, or polygonal cells, termed decidual cells. Their enlargement is due to glycogen and lipid accumulation in the cytoplasm allowing these cells to provide a rich source of nutrition for the developing embryo.rom Wikipedia, the free encyclopedia. Before the fertilized ovum reaches the uterus, the mucous membrane of the body of the uterus undergoes important changes and is then known as the decidua.
Squamous cell carcinoma (SCC) is the most common type of head and neck cancer. More than 6 out of 10 nasal cavity and paranasal sinus cancers (60%) are SCCs. Squamous cells are the flat, skin like cells that cover the lining of the mouth, nose, larynx, thyroid and throat.everal layers of tissue make up each part of the nasal cavity (nose) and paranasal sinuses. Each layer contains many different types of cells. Different cancers can develop from each type of cell. It is important for doctors to recognise the type to help them decide on how best to treat the cancer.
