Abstract:
Groups of mechanoreceptive sensilla form small sensory fields on the ventral rim of the most distal tarsomeres in insects. Within these fields two or three sensilla are located closely together. Anterior and posterior fields are found in all three pairs of legs with only a few exceptions. The composition, exact location, and morphology of the fields were studied in representative species of several insect orders using light and scanning electron microscopy. There was no obvious correlation between field morphology and insect phylogenetic relationships.

Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...

Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....
