Question: 145: Tegmina in cockroach, arises from
(1) Metathorax
(2) Prothorax and Mesothorax
(3) Prothorax
(4) Mesothorax
Answer: Option (4)
Explanation:
In cockroach, the thorax is divided into three segments: prothorax, mesothorax, and metathorax.
The forewings of cockroach are called tegmina.
Tegmina arise from the mesothorax and are leathery in texture.
They cover and protect the hind wings and the dorsal surface of the abdomen.
The hind wings arise from the metathorax and are membranous, which help in flight.
Therefore, tegmina in cockroach arise from the mesothorax.
