Write about the sense organs of cockroach.

Explanation

In cockroach, the sense organs are antennae, compound eyes, labrum, maxillary palm labial palps and anal cerci. The receptor for touch (thigmo receptors) is located in the antenna, maxillary palps and cerei. The receptor for smell (olfactory receptors) is an on the antennae. The receptor for faste (gustatory receptors) is found on the palps maxilla and labium. Thermoreceptors are found on the first four tarsal segments on the legs. The receptor chordotonal is found on the anal cerei which respond to air or canti bome vibrations. The photoreceptors of the cockroach consists of a pair of compound eyes at the dorsal surface of the head. Each eye is formed of about 2000 simple eyes called the ommatidia (singular: ommatidium), through which the cockroach can receive several images of an object. This kind of vision is known as mosaic vision with more sensitivity but less resolution
