where do calluses on your feet come from
Callus A callus is an area of thickened skin in response to repeated friction, pressure, or other irritation. Rubbing that is too frequent or forceful will cause blisters rather than allow calluses to form. Since repeated contact is required, calluses are most often found on feet because of frequent walking and incorrectly fitting footwear. Calluses are generally not harmful, but may sometimes lead to other problems, such as anskin ulceration or infection or cause the sufferer to try and offload the effected painful area, which can place excessive stress on the asymptomatic side.
Dorsalis pedis artery In human anatomy, the dorsalis pedis artery (dorsal artery of foot), is a blood vessel of the lower limb that carries oxygenated blood to the dorsal surface of the foot. It arises at the anterior aspect of the ankle joint and is a continuation of the anterior tibial artery. It terminates at the proximal part of the first intermetatarsal space, where it divides into two branches, the first dorsal metatarsal artery and the deep plantar artery. The dorsalis pedis communicates with the plantar blood supply of the foot through the deep plantar artery.
