Nerve arising from abdominal ganglia in cockroach are found inA. AbdomenB. Thoracic musclesC. WingsD. Legs

The correct answer is A. Abdomen.

Here’s the detailed explanation:

In cockroaches, the nervous system is composed of a brain and a ventral nerve cord, which runs along the length of the body. The nerve cord has ganglia (nerve clusters) in each segment, and the abdominal ganglia are located in the abdomen region.

The abdominal ganglia control the movements and functions of the abdominal segments, including the digestive system, excretion, and certain muscular movements. Nerves arise from these ganglia and are distributed to the abdominal muscles and other structures in the abdomen.

Thus, the nerves arising from the abdominal ganglia are found in the abdomen of the cockroach.
