Tibialis Anterior Anatomy Study: Origin, Insertion, Actions, Innervation, Blood Supply
Origin: Lateral condyle and proximal half to two-thirds of the lateral surface of the tibial shaft, the adjoining anterior surface of the interosseous membrane and the intermuscular septum between it and the extensor digitorum longus.
Insertion: Inferomedial aspect of the medial cuneiform and base of the first metatarsal.
Action: Inverts and adducts the free foot, assists in plantar flexion. Prevents excessive pronation of the foot during walking.
Innervation: Deep Peroneal nerve (L4 – 5 )
Blood Supply: Branches from the anterior tibial artery
Synergist: Extensor hallucis longus, Extensor digitorum longus, and Peroneus tertius
Antagonist: Gastrocnemius, Flexor digitorum longus, Flexor hallucis longus, Peroneus longus, Peroneus brevis, Tibialis posterior, Soleus, Plantaris
Primary Actions of the Tibialis Anterior:
1. Dorsiflexion of the foot at the ankle
Antagonists: Gastrocnemius, Soleus
2. Inversion of the foot at the subtalar joint
Agonists: Tibialis Posterior
Antagonists: Peroneus Longus, Peroneus Brevis
Secondary Action of the Tibialis Anterior:

Human Anatomy Study Guides
Musculoskeletal Anatomy Flashcards Are you a student or professional therapist who needs to brush up on the musculoskeletal system? Dr. Joseph E. Muscolino DC has developed a comprehensive set of flashcards that will help develop a mind’s picture of exactly where the muscles lie under the skin. A highly recommended study aid for students. Great for non students who want an easy comprehensive anatomy guide.
Trail Guide To The Body
The Trail Guide To The Body is another excellent book to help you learn the musculature of the human body. Though the book is geared toward massage therapists and physical therapist assistants, the book with its illustrations and text helps anyone gain a thorough understanding of the human musculoskeletal system and movement. I highly recommend this book for anyone studying anatomy and believe that MTs, PTAs, and teachers of body movements should have this book in their possession. I also highly recommend this book for the lay person who wants to gain understanding of the muscle, skeletal system and how our bodies move. This book will not disappoint!
