What structures are found in an insect’s abdomen?
In most insects clear segmentation can be seen in the abdomen. The abdomen contains the heart, reproductive organs, mid-gut and other digestive organs.
What are abdominal appendages in insects?
In females, paired appendages of the eighth and ninth abdominal segment fit together to form an egg-laying mechanism called the ovipositor. These appendages consist of four valvifers (basal sclerites with muscle attachments) and six valvulae (apical sclerites which guide the egg as it emerges from the female’s body).
Which part of the body is called the groin?
Overview. The inguinal region of the body, also known as the groin, is located on the lower portion of the anterior abdominal wall, with the thigh inferiorly, the pubic tubercle medially, and the anterior superior iliac spine (ASIS) superolaterally.

What is in an insect’s thorax?

Where are the cerci located?
Cerci (singular cercus) are paired appendages on the rear-most segments of many arthropods, including insects and symphylans. Many forms of cerci serve as sensory organs, but some serve as pinching weapons or as organs of copulation. In many insects, they simply may be functionless vestigial structures.
What is Epiproct and Paraproct?
In all insects the 11th segment is reduced. In the grasshopper, the 11th segment is reduced to a tergal plate called the epiproct, and 2 lateroventral plates called paraprocts. It can also be united with the 10th segment (as in some Homoptera) to form an anal tube.
