(Greek: foot, feet)
2. An infectious bacterial disease of sheep, goats, and cattle that is associated with warm, wet, unhygienic conditions, characterized by lameness due to erosion of the horny structures and inflammation of the related soft parts of the foot.
This nomenclature (Podokesaurus, “swift-footed lizard”) is no longer recognized by scientists because they found that it described an animal that was previously given another name which is Coelophysis; named by US paleontologist Mignon Talbot in 1911.
2. The specialty concerned with the diagnosis and medical, surgical, mechanical, physical, and adjunctive treatment of the diseases, injuries, and defects of the feet.
3. The medical study of feet and their treatment.
These microscopic assemblies seem to form "feet" on the bottom surface of the leading edge of migrating cells which indicate a location consistent with the idea that they help cells move.
Cell biologists have discovered structures on a variety of migratory cells, including immune cells called macrophages and osteoclasts which help maintain bone by dissolving away areas that need repair. In all cases, the structures appear when the cells make contact with a surface. This suggests that they might be involved in cell adhesion, and thus in cell motility, because cells have to stick to the surface over which they are migrating in order to move.
