part of thorax thoracic leg 2013-02-28T12:19:15Z BTO:0001503 BrendaTissueOBO The arthropod leg is a form of jointed appendage of arthropods, usually used for walking. Many of the terms used for arthropod leg segments (called podomeres) are of Latin origin, and may be confused with terms for bones: coxa (meaning hip), trochanter, femur, tibia, tarsus, ischium, metatarsus, carpus, dactylus (meaning finger), patella. The typical thoracic leg of an adult insect is adapted for running, rather than for digging, leaping, swimming, predation or the like. XPMUser
