Extensor Hallucis Longus Muscle Innervation Anatomy Human Anatomy Kenhub
Hey, everyone. It's Matt from Kenhub! Andin this tutorial, we will discuss the anatomy and function of the extensor hallucis longus. The extensor hallucis longus or in Latin,â€œmusculus extensor hallucis longus,â€� is one of three anterior muscles that functionas extensors at the lower leg. They lie within the anterior compartment locatedat the ventrolateral region of the lower leg where they form its surface structure. Their tendons are particularly prominent onthe dorsum of the foot. The extensor hallucis longus has its originat the medial side of the fibula and interosseous
membrane. It merges into a tendon above thesuperior extensor retinaculum as well. Its insertion is the distal phalanx of thebig toe. All anterior muscles are innervated by thedeep fibular nerve, also called the deep peroneal nerve. The main function of the anterior musclesof the lower leg is the dorsal extension of the upper ankle joint. In addition, the extensor hallucis longusis partly responsible for the lifting of the toes or the extension of the first, middle,and end joints.
Due to the course of the tendons, the anteriormuscles also contribute to the movement of the lower ankle joint. The extensor hallucis longus can provide bothan inversion and eversion of the ankle joint depending on the initial situation.

Arteries and nerves of the foot preview Human Anatomy Kenhub
Hello, everyone! This is Joao from Kenhub,and welcome to another anatomy tutorial where, right now, we're going to be talking aboutthe different arteries and also nerves that you find on your foot. Right now, on your screen, we're lookingat the plantar view of your foot where we can see, on the left side, the different arteriesthat we're going to be talking about on this tutorial as well as the different nervesthat you see on the right side, on the image on the right side. Now, as I just mentioned, then, we're goingto be focusing on the main arteries and also
nerves that we find on your foot. Before wedo so, let's start out by listing the different arteries that we're going to be covering.We're going to talk about the dorsal artery of the foot, the lateral and medial tarsalarteries, the arcuate artery, also the dorsal metatarsal arteries, the lateral and medialplantar arteries, the deep plantar arch and, finally, we're going to also be talkingabout the plantar metatarsal arteries.
