Arthropod leg

Form of jointed appendage of arthropods

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, pl.: coxae), trochanter, femur (pl.: femora), tibia (pl.: tibiae), tarsus (pl.: tarsi), ischium (pl.: ischia), metatarsus, carpus, dactylus (meaning finger), patella (pl.: patellae). Homologies of leg segments between groups are difficult to prove and are the source of much argument.
