Toes are the digits of the foot of a tetrapod. Animal species such as cats that walk on their toes are described as being ''digitigrade''. Humans, and other animals that walk on the soles of their feet, are described as being ''plantigrade''; ''unguligrade'' animals are those that walk on hooves at the tips of their toes. ==Structure== The toe refers to a part of the human foot, with five toes present on each human foot. Each toe consists of three phalanx bones, the proximal, middle, and distal, with the exception of the big toe ((ラテン語:Hallux)). The hallux only contains two phalanx bones, the proximal and distal. The phalanx bones of the toe join to the metatarsal bones of the foot at the interphalangeal joints. Outside the hallux bones is skin, and present on all five toes is a toenail. The toes are, from medial to lateral: * The first toe, also known as the hallux ("big toe" or "great toe"), the innermost toe * The second toe, or "long toe" * The third toe, or "middle toe" * The fourth toe, or "ring toe" * The fifth toe, "little toe", "pinky toe", or "baby toe", the outermost toe. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「toe」の詳細全文を読む スポンサード リンク
