Cockroach Physiology

Cockroach Physiology


Ever wondered how the body of a cockroach work? Or these little creatures push you enough to make you want to delete them from existence? Maybe learn about these insects and the study of their structure and physiological functions could help find ways to control and get rid of these parasites.

Most people are able to recognize a cockroach, even when they ran along a distance. The sight of their blackish, brownish flattened bodies and long antennae prominent enough to send a human scream and shout "cockroach alert!" Adding to the "squirm factor" when it encounters a male cockroach, you may notice that some have wings that can barely fly, even if some do try!

The head of the cockroach is where it's eyes, mouthparts and antennae, as well as brains. As important as the head may seem, a cockroach can live surprisingly more than a week without its head! This is because, most of its functions of the nervous system occurs in the nerve ganglia that is throughout her body. In addition, roach do not breathe through the nose or mouth, but it breathes air through the holes in their sides called spiracles. The air then passes through tubes called tracheae, which feeds the organs and tissues of oxygen. You may not be able to stifle a headless cockroach but once he lost his head, it will eventually die from lack of water, their most valuable substance.

Cockroaches are able to feel and experience using their mobile long antennae, which are made from many small segments hair covered. An experiment conducted by Makoto Mizunami and Hidehiro Watanabe of Tohoku University took the obsession with cockroaches with sugar test their sense of smell through their antennae and observe their reactions. Experience has shown that their tiny brains were able to remember and associate in the sense of smell and respond, just like dogs and humans by salivating.

Cockroaches can have a very limited vision, but they are extremely sensitive to changes and movements of light and also the sound waves, they detect by sensory hairs located on their tail, the lower part of the abdomen. Inside the nerve of the cockroach with its sensory organs detect movement that is less than a millionth of a millimeter - a fraction of accuracy the first place! This is what explains how these little creatures can scuttle away so fast even when you come near it, let alone try to catch and crush. Perhaps there should be a capture device that can move quietly at a higher speed than the cockroaches!
