Fibula
Outer and narrower of 2 lower-leg bones; extending from knee to ankle
Talus
Ankle bone; sits above the heel bone and forms the lower part of the ankle; talus, tibia, and fibula form the ankle joint
Tarsals
7 bones that make up the mid-foot and rear foot, including talus, calcaneus(heel), navicular, 3 cuneiform bones and the cuboid
Metatarsal
5 long, slender bones (1 for each digit) that connect the phalanges to the tarsals
Phalanges
14 bones that form the digits or toes; 2 phalanges in the big toe and 3 in the 4 other toes; proximal, middle, and distal
Leg bones
Femur, patella, tibia, fibula
Ankle bones
Talus, tarsals
Foot bones
Phalanges and metatarsals
Arm bones
Humerus, radia, and ulna
Wrist bones
