FAQs on Cockroach: Thorax & Anatomy Video Lecture - Biology for Grade 11
| 1. What is the thorax of a cockroach and what is its function? |  |
Ans. The thorax of a cockroach is the middle part of its body, located between the head and the abdomen. It consists of three segments, each with a pair of legs attached. The main function of the thorax is to support and facilitate movement for the cockroach.
| 2. How does the anatomy of a cockroach's thorax contribute to its ability to fly? | |
Ans. The anatomy of a cockroach's thorax plays a crucial role in its ability to fly. The thorax contains powerful flight muscles that are responsible for wing movement. These muscles are attached to the exoskeleton, allowing the wings to move rapidly and generate the necessary lift for flight.
| 3. What are the different parts of a cockroach's thorax? | |
Ans. The thorax of a cockroach is composed of three segments: the prothorax, mesothorax, and metathorax. Each segment has a pair of legs attached, making a total of six legs. Additionally, the wings are attached to the mesothorax and metathorax segments.
| 4. How is the thorax of a cockroach structurally adapted for its survival? | |
Ans. The thorax of a cockroach is structurally adapted to enhance its survival in several ways. It has a strong and rigid exoskeleton that provides protection against predators and physical damage. The presence of powerful flight muscles enables the cockroach to escape quickly from potential threats. The segmentation of the thorax allows for flexible movement and coordination of the legs during locomotion.
| 5. How does the thorax of a cockroach contribute to its sensory perception? | |
Ans. The thorax of a cockroach contains sensory organs called sensilla, which are responsible for detecting various stimuli. These sensilla can sense touch, temperature, humidity, and air currents, providing the cockroach with information about its surroundings. The sensilla in the thorax help the cockroach navigate its environment, locate food, and avoid potential dangers.
