Adductor Magnus Muscle - Function & Origins - Human Anatomy | Kenhub

Summary

In this tutorial by Kenhub, Matt explains the adductor magnus muscle, a key component of the hip adductors located in the medial thigh. He details its origin from the pelvic bones, its insertion at the femur, and its innervation by the obturator and tibial nerves. The adductor magnus is primarily responsible for hip adduction and assists in outward and inward rotation, flexion, and extension. The tutorial emphasizes the muscle's role in maintaining pelvic balance during activities like standing and walking, encouraging viewers to transition from traditional textbooks to interactive learning on Kenhub.

Takeaways

• 🦵 The adductor magnus is one of the largest muscles in the human body.
• 📍 It originates from the inferior pubic ramus, ischial ramus, and ischial tuberosity.
• 🔗 The adductor magnus inserts at the linea aspera and the adductor tubercle of the medial epicondyle.
• 💡 Its primary innervation comes from the obturator nerve, with additional supply from the tibial nerve for the superficial part.
• ➡️ The main function of the adductor magnus is the adduction of the hip joint.
• 🔄 It also supports outward rotation, inward rotation, flexion, and extension of the hip.
• ⚖️ The hip adductors, including the adductor magnus, play a vital role in pelvic balance during standing and walking.
• 🎓 The video aims to provide a more engaging learning experience compared to traditional textbooks.
• 🖥️ Kenhub offers videos, quizzes, articles, and an anatomy atlas for enhanced learning.
• 👋 The tutorial encourages viewers to transition from textbooks to more interactive learning methods.
