◉ Pastern (hooved).
Answer: area between fetlock and hoof
◉ Carpus.
Answer: wrist of humans
◉ Tarsus.
Answer: ankle of humans → hock
◉ Carpal pads.
Answer: only on thoracic feet
◉ Metacarpal and metatarsal pads.
Answer: thoracic foot (metacarpal) or pelvic foot (metatarsal)
,◉ Numbering.
Answer: Medial to lateral
Thoracic: 1 = dew claw (thumb, medial), 2, 3, 4, 5 (lateral)
