Kidney a minor calyx; minor calyces empty into major calyces, and major calyces empty into the renal pelvis. This becomes the ureter. At the hilum, the ureter and renal vein exit the kidney and the renal artery enters. Hilar fat and lymphatic tissue with lymph nodes surrounds these structures. The hilar fat is contiguous with a fat-filled cavity called the renal sinus. The renal sinus collectively contains the renal pelvis and calyces and separates these structures from the renal medullary tissue. The kidneys possess no overtly moving structures. The renal circulation supplies the blood to the kidneys via the renal arteries,
Medial plantar artery of the first three spaces. A superficial branch which supplies a plantar digital artery to the medial side of the 1st toe, and a deep branch which assists in supplying blood to the plantar metatarsal arteries. Medial plantar artery The medial plantar artery (internal plantar artery), much smaller than the lateral plantar artery, passes forward along the medial side of the foot. It is at first situated above the abductor hallucis, and then between it and the flexor digitorum brevis, both of which it supplies. At the base of the first metatarsal bone, where it is much diminished in size,
