Hemideina ricta The thorax contains the front, middle and hind legs of the weta, each leg is made up of six segments; the coxa, the trochanter, the femur, the tibia, the tarsus and the pretarsus. The ear of the weta can be found at the top of the tibia near the knee joint of the front legs. The tibia of the hind legs are covered in spines, that can be rubbed against the stridulatory ridges on the side of the body to produce a sound, these can also be used as a defence mechanism against predators.

Superior tibiofibular joint Superior tibiofibular joint The proximal tibiofibular articulation (also called superior tibiofibular joint) is an arthrodial joint between the lateral condyle of the tibia and the head of the fibula. The contiguous surfaces of the bones present flat, oval facets covered with cartilage and connected together by an articular capsule and by anterior and posterior ligaments. When the term "tibiofibular articulation" is used without a modifier, it refers to the proximal, not the distal (i.e., inferior) tibiofibular articulation. Injuries to the proximal tibiofibular joint are uncommon and usually associated with other injuries to the lower leg. Dislocations can be classified into
