Nematodes are animals that have three layers of the body (tripoblastik) bagger or blastula consists

Nematodes are from NEMA said: yarn and oidos: shape. In classis nematodes, cuticles plain or bercicin-ring, most have stiff hairs, ciliated. The cuticle is modified towards the superficial epidermis. bagger Beneath the epidermis there is a layer of muscle that only consists of longitudinal fibers only.
Pharynx lumen in cross-sectional bagger shape triradial. Excretoria organs are not composed of protonephridia, but consist of: 1 or 2 or canal excretorius glandular cells or both.
Nematodes are known as "roundworms" or roundworms. This worm is very active, slender, usually tapered at both ends, and has a mouth and anus, so have a complete digestive tract. Body cavity called "pseudoselom". Two of them are famous Ascaris lumbricoides, intestinal roundworms in humans and Entrobius vermicularis, pinworms in young children.
Among all aschelminthes, nematode phylum has the most members, 10,000 known species. Most species of free-living nematodes, both in marine, brackish water, fresh water and soil; cold of the polar regions to the tropics; in a variety of habitats such as the desert and the sea, as well as a number of parasitic species that live on plants and animals . So once widely spread. At sea mud ever encountered nematode worms 4 million bagger per m , in ground waters 100 million worms types teres-terial per m , the fish is very famous because of the worm that infects. Types of parasites are also quite a lot, and attack plants and animals, so often times detrimental to farmers and ranchers.
Nematodes are organisms that have a simple structure. Body length slindris closed cuticle, straight and complete digestive bagger tract, the body in the form of tebung called pseudocoelomate. Adult nematodes composed by thousands of somatic cells, hundreds of them forming reproductive cells.
Nematodes are animals that have three layers of the body (tripoblastik) bagger or blastula consists of three layers, these layers are formed bagger and develop in the egg. Having a body wall composed of outer cuticle, a layer between, hypodermis, and the inside of the longitudinal muscle. The cuticle is the outer part of the body wall.
Epidermisnya thin but forming bagger four longitudinal cords. bagger Below the epidermis there is a layer of muscle fibers extending longitudinally and divided by ropes into 4 kuadrans. Complete digestive tract eating, straight, mouth and anus are at different ends. Among the body wall and the digestive tract are called space or cavity pseudosoel. Do not have the organs of circulation and respiration. Simple bagger excretion organs.
A large number of nematode species live as endoparasites, no eksoparasit. As endoparasites require one or more hosts. Endo parasites in fish such as Spinitectus, bagger Cammalanus longitridentatus or Philometra sanguinea.
Classes consist of several species of nematodes not only parasitical bagger on humans, but also for animals. Including parasitic nematodes can only feed on living plant tissue, the fluid absorbs its host cells or tissues bagger using a piercer and sucking mouth cavity, known as "stylet". Most of parasitic nematodes attack the roots or plant parts below the soil surface, although some are attacking stems, buds, leaves, and seeds relationship.
Parasitic nematode Meloidogyne generally bagger be settled as sp, sp Rotylenchus reniformis bagger and gobodera. This species is found in the root tissue in a state of the worm is turning into a rounded shape (like the shape of the bottle). Most of the species bagger Globodera already formed cyst attached to the anterior portion, the body infiltrate in the cortex, while the posterior part outside bagger the root network (semi-endoparasites). bagger Sista rounded shape (globular or spheroid), most of the yellow color of gold, some white and dark yellow to brown.
Important parasites in humans include whipworms, hookworms hook worms, Pinworms, ascarids, and Filarids. Another important roundworm Caenorhabditis elegans is. Endoparasitic nematodes live as a human with an intermediary host for example elephantiasis or filariasis or elaphantiasis caused by mosquitoes that require Wucheria bancrofti as an intermediary host.
Nematode parasites that normally infect animals is capable of killing a human Baylisascaris too. Haemonchus contortus is one of the commonly attacks the sheep around the world, causing economic pressure to pe
