What is the origin and insertion of the Anterior Tibialis?
|
Origin: Lateral condyle and proximal two-thirds of the lateral surface of the tibia.
Insertion: Medial and plantar aspects of the medial cuneiform and the base of the first metatarsal. |
|
|
What is the isolated function of the Anterior Tibialis?
|
Concentrically accelerates dorsiflexion and inversion
|
|
|
What is the integrated function of the Anterior Tibialis?
|
*Eccentrically decelerates plantar flexion and eversion.
*Isometrically stabilizes the arch of the foot. |
|
|
What is the origin and insertion of the Posterior Tibialis?
|
Origin: Proximal two-thirds of posterior surface of the tibia and fibula.
Insertion: Every tarsal bone but the talus, plus the bases of the second through the fourth metatarsal bones. The main insertion is on the navicular tuberosity and the medial cuneiform bone. |

|
|
What is the origin and insertion of the Peroneus Longus?
|
Origin: Lateral condyle of tibia, head, and proximal two-thirds of the lateral surface of the fibula.
Insertion: Lateral surface of the medial cuneiform and lateral side of the base of the first metatarsal. |
|
|
What is the isolated function of the Peroneus Longus?
|
Concentrically plantarflexes and everts the foot.
|
|
|
What is the integrated function of the Peroneus Longus?
|
*Decelerates ankle dorsiflexion.
*Isometrically stabilizes the foot and ankle complex. |
