The nervous system is the only place in the body that contains cilia; ... The single genus Meloidogyne (root-knot nematodes) exhibits a range of reproductive modes, ...
Male nematodes may have one or two spicules which serve to open the vulva of females and facilitate the transmission of sperm, although sperm is not transferred directly by or through the spicules. [ 2 ] [ 3 ] The gubernaculum is another organ of the nematode male copulatory system which guides the spicules during copulation.
Spicule (nematode), reproductive structures found in male nematodes (roundworms) Spicule (solar physics) , jets of solar material from the Sun Spicule (glass manufacture) , glass flakes formed in the production of glass vials.
The reproductive system includes one or more testes, cirri, vas deferens, and seminal vesicles as male organs, and a single lobed or unlobed ovary with the connecting oviduct and uterus as female organs. The common external opening for both male and female reproductive systems is known as the genital pore, which is situated at the surface ...
Nematomorpha (sometimes called Gordiacea, and commonly known as horsehair worms, hairsnakes, [1] [2] [3] or Gordian worms) are a phylum of parasitoid animals superficially similar to nematode worms in morphology, hence the name. Most species range in size from 50 to 100 millimetres (2.0 to 3.9 in), reaching 2 metres (79 in) in extreme cases ...
A bacterivore is an organism which obtains energy and nutrients primarily or entirely from the consumption of bacteria.The term is most commonly used to describe free-living, heterotrophic, microscopic organisms such as nematodes as well as many species of amoeba and numerous other types of protozoans, but some macroscopic invertebrates are also bacterivores, including sponges, polychaetes ...
Nematology research, like most fields of science, has its foundations in observations and the recording of these observations. The earliest written account of a nematode "sighting," as it were, may be found in the Pentateuch of the Old Testament in the Bible, in the Fourth Book of Moses called Numbers: "And the Lord sent fiery serpents among the people, and they bit the people; and much people ...
The female reproductive system consists of one ovary connected to an elongated uterus by a ciliated oviduct. The uterus opens to the exterior at the genital pore (the common external opening of the male and female reproductive systems). The location of the ovary varies among different species, making the female reproductive system useful in ...
