==Overview==
The structure of a nematode is intimately related to its function and its life cycle. Although there are common traits throughout the phylum there is also great diversity allowing each species to occupy a niche in which it may thrive.
==Body Structure==
The nematode body is elongated and smooth with no limbs protruding, such as is seen in the common garden worm though generally on a smaller scale. The body is contained within a tough elastic '''cuticle''' which in many species forms elaborate structures useful for identification.
==Locomotion==
==Nervous System==
Knowledge of the nervous system employed by nematodes has enabled the development of many anti-parasitic drugs as they work to disrupt this system. There is a neural ring around the pharynx of the nematode containing 4 ganglia which communicate distally to the body of the nematode to co-ordinate movement.
==Feeding and Digestion==

*A unique feature of the nematodes is that the fluid in the body cavity is maintained under high pressure (this is why nematodes often burst after collection)
