Question

In cockroach, thermoreceptor sensillae lie:

• A. In thorax
• B. In abdomen
• C. On trochanter
• D. On first three tarsomeres

Hint:

The first three tarsomeres of a cockroach's legs contain thermoreceptor sensillae, which help the cockroach detect environmental temperature changes.

Answer 1

The Correct Option is D

- Thermoreceptor sensillae in cockroaches are primarily found on the first three tarsomeres of the legs, which help in detecting temperature changes.
- The thorax and abdomen contain other sensory structures but not thermoreceptor sensillae.
- The trochanter is a part of the cockroach's leg but does not specifically house thermoreceptor sensillae.
