through to the lymph nodes (Elephantiasis‚ 2015). The blockage causes the lymph to build up in the body‚ and swell around the limb where the blockage occurs (Elephantiasis Tropica‚ 2014). Also‚ elephantiasis can be caused by mosquitoes infected with roundworms. When this is the cause‚ the disease is referred to as‚ Lymphatic filariasis; however‚ the names are interchangeable. This type of elephantiasis is

Tapeworms are the dominant member of the class Cestoidea. They are ribbon-like‚ segmented creatures living in the intestines of their vertebrate hosts. There are a dozen orders in this class‚ most living in fish but two that use humans as hosts. Tapeworms cling to the intestinal wall of their hosts with suckers‚ hooks‚ or other adhesive devices. Having no mouth or gut‚ they receive their nourishment through their skin. Further‚ they have no type of sensory organs. White or yellowish in color‚ species

Ascariasis What is Ascariasis? Ascariasis is a disease caused by the parasitic roundworm Ascaris lumbricoides. Infections have no symptoms in more than 85% of cases‚ especially if the number of worms is small. Symptoms increase with the number of worms present and may include shortness of breath and fever in the beginning of the disease. These may be followed by symptoms of abdominal swelling‚ abdominal pain and diarrhea. Children are most commonly affected‚ and in this age group the infection

Significance of Planarians Planarians are non-parasitic flatworms of the phylum Platyhelmintes found in fresh water like ponds or lakes. In my research paper I focused on Schmidtea mediterranea planarians found in Tusinia and southern Europe which are extensively used as a model organism to study development and regeneration process (Newmark 2012). Schmidtea mediterranea are chosen by researcher in molecular biology and genetics field because these planarians have diploid chromosomes and are hermaphrodite

Chapter 32 – An Introduction to Animal Diversity All animals share a common ancestor‚ sponges are basal animals‚ eumetazoa is a clade of animals with true tissues‚ most animal phyla belong to the clade bilateria‚ and vertebrates and some other phyla belong Animals share a unique homeobox-containing family of genes‚ known as the Hox genes‚ suggesting that this gene family evolved in the eukaryote lineage that gave rise to animals. Hox genes play important roles in the development of animal embryos
