Muscles of facial expression

This video tutorial provides an in-depth exploration of the arteries and nerves of the foot. It begins with an overview of the main arteries, including the dorsal artery and its branches, such as the lateral and medial tarsal arteries. The tutorial then covers the arcuate artery and the dorsal metatarsal arteries, followed by a detailed look at the plantar arteries and the deep plantar arch. The second half of the video focuses on the nerves of the foot, including the dorsal digital nerves and the lateral and medial plantar nerves. The tutorial concludes with suggestions for further learning.
