TIBIA

The major weight-bearing bone of the lower leg
tibia articulates:

proximal: distal femur
twice lateral: fibula ( one proximal/one distal)
distal: talus( is called: astragalus in other animalsplace between fibula and tibia)
tibia parts are:
tibia plateau
medial condyle
lateral //
intercondylar eminence
medial intercondylar tubercle
lateral // //
superior fibular articulate facet
tibial tuberosity
tibial shaft
soleal (popliteal)lines
nutrient foramen
anterior surface (anterior crest)
medial surface
interosseus surface
// crest
medial malleolus
fibular notch
inferior fibular articulate surface
malleolar groove

Tibia ossifies from three center
shaft and two each end of the bone

Tibia shaft is mauch larger than ulnar or radial shafts the proximal and distal ends could be mistaken with proximal articular surface for the body of vertebra but the tibia articular surface is much smoother and denser.
