Приложение

Отличное приложение для изучения. Лично я использую его на данный момент вместе с профессиональным переобучением. Наглядно можно глянуть крепления мышц, их диапазон движения.
В приложении много и других функций. Но я на этапе изучения анатомии использую их.
Рекомендую использовать как доп.материал при изучение.
