This term is often referred to only for outer limbs but it pertains to our inner topography as well.
Decapitations, dismembering, slow shooting in the outer limbs until the victim begs to die, teachers assassinated and their schools turned into indoctrination centers by one armed force or another, all surrounded by an otherwise peaceful jungle: these are among the stories recounted in several dozen almost chromatic paintings.
The arthropod crown group (indicated by character G in Fig. 3) shares certain features not present in the stem group fossils, notably a reduced number of articles in the inner limb branch (only five to seven articles excluding the terminal claw versus eight in Leanchoilia) and more rod-like rather than flap-like outer limb branches.
We can infer, for example, that jointed appendages, an outer limb branch (an exite), a stiffened tergal exoskeleton, compound eyes, and a hypostome are characters that evolved before the crown group node for the Arthropoda (jointed appendages and compound eyes probably evolved earlier than the fuxianhuiids, as evidenced by their presence in anomalocaridids: Fig. 5B).

These have been interpreted as homologous to the outer branch of the arthropod limb – the exopod (in anomalocaridids [ 19] and by extension, presumably for other lower-stem groups) or as gill-bearing body-wall outgrowths [ 35, 36].
In bottom-dwelling species, however, the inner branch has become a stiff walking limb, and the slender multisegmented outer branch is variously reduced (in hemicarideans) or lost altogether (in amphipods and isopods).
The trunk limbs have two branches, as in many Palaeozoic arthropods (such as trilobites, to cite the most familiar example), but the outer branch is a simple rounded flap that lacks strong setae.
A pollinator visiting the flower in search of nectar alights on the lower lip (outer tepal limb) and pushes its head and mouthparts into the gullet (the space between the tepal claw and style branch).
They occur predominately on the most exposed and cooler areas (4, 6 ): i.e., head, back, dorsal fin, flanks, caudal peduncle, and tail in dolphins; and lower limbs, outer ears, upper limbs, and face in humans.
