Tibialis Anterior - Podcast Version 0:00 / 0:00 1x 0.25x 0.5x 0.75x 1x 1.25x 1.5x 1.75x 2x The tibialis anterior is a muscle within the anterior compartment of the leg. It can be palpated just lateral to the shaft of the tibia. Attachments: Originates from the lateral surface of the tibia and attaches to the medial cuneiform bone and the base of metatarsal I. Actions: Dorsiflexion and inversion of the foot Innervation: Deep fibular nerve Blood supply: Anterior tibial artery By TeachMeSeries Ltd (2026) Fig 1The muscles of the anterior leg.

Learn More Frequent questions What is the tibialis anterior muscle? The tibialis anterior is a muscle located in the anterior compartment of the leg, responsible for foot movements. It is easily palpated just lateral to the tibial shaft. What are the attachments of the tibialis anterior? The tibialis anterior originates from the lateral surface of the tibia and attaches to the medial cuneiform bone and the base of the first metatarsal. These attachments facilitate its functional role in foot movement. What actions does the tibialis anterior perform? The primary actions of the tibialis anterior include dorsiflexion and inversion of the foot. These movements are crucial for activities such as walking and running. Which nerve innervates the tibialis anterior? The tibialis anterior is innervated by the deep fibular nerve. This nerve is essential for controlling the muscle's function during movement. What is the blood supply to the tibialis anterior? The blood supply to the tibialis anterior muscle comes from the anterior tibial artery. This vascular supply is important for maintaining muscle health and function. Rate This Article
