What does Miracidium mean?
Definition of miracidium : the free-swimming ciliated first larva of a digenetic trematode that seeks out and penetrates a suitable snail intermediate host in which it develops into a sporocyst.
What stage of trematodes swim in water?
The hatchling is called a miracidium, a free-swimming, ciliated larva. Miracidia will then grow and develop within the intermediate host into a sac-like structure known as a sporocyst or into rediae, either of which may give rise to free-swimming, motile cercariae larvae.
What is a Redia?
Definition of redia : a larval form of a digenetic trematode (such as a liver fluke) that is produced within a sporocyst, has a mouth, pharynx, and gut, and contains cells which give rise to other rediae or to cercariae — see also redial entry 3.
What is Anhedral and what is its purpose?
Anhedral angles are when the wing tips are lower than the wing base and are used on smaller planes like fighter planes. This angle increases the roll performance.
What is Encyst?
Definition of encyst transitive verb. : to enclose in a cyst. intransitive verb. : to form or become enclosed in a cyst.
Where is miracidium larva found?
platyhelminthes. The first larval stage, the miracidium, generally is free-swimming and penetrates a freshwater or marine snail, unless it has already been ingested by one. Within this intermediate host, the parasite passes through a series of further stages known as sporocysts, rediae, and cercariae.
Which disease is caused by trematodes?
Key facts
| Disease | Infectious agent | Acquired through consumption of |
|---|---|---|
| Clonorchiasis | Clonorchis sinensis | Freshwater fish |
| Opisthorchiasis | Opisthorchis viverrini, O. felineus | Freshwater fish |
| Fascioliasis | Fasciola hepatica, F. gigantica | Aquatic vegetables |
| Paragonimiasis | Paragonimus spp. | Freshwater crustaceans (crabs and crayfish) |
What is a redia?
Why do Russian planes have Anhedral wings?
Anhedral wings will induce roll instability and improve roll maneuverability. In a large/heavy airplane with a high-wing configuration there is usually excess roll stability, so this type of wings can be pretty common.
What is meant by Amoebulae?
Medical Definition of amebula 1 : a small amoeba. 2 : any of various small cells or organisms (as in some stages of myxomycetes or gregarines) resembling an amoeba in form.
