Where does the peroneus longus attach?
Where does the peroneus longus attach?
Function. The peroneus longus courses down the lateral aspect of your lower leg and attaches around the lateral foot and on the bottom of your foot. When it contracts, it moves your ankle into eversion.
What is the distal attachment of peroneus brevis?
Fibularis brevis, or peroneus brevis, is a short muscle that together with the fibularis (peroneus) longus comprises the group of the lateral leg muscles….Fibularis brevis muscle.
| Origin | Distal 2/3 of the lateral surface of fibula, anterior inermuscular septum |
|---|---|
| Insertion | Tuberosity of the 5th metatarsal bone |
What are the attachments of the fibularis longus?
Fibularis longus attaches on the medial aspect of the foot at the base of the first metatarsal and medial cuneiform bone, lateral to the attachment of tibialis anterior on the same bones.
Where does the peroneus brevis attach?
Peroneus brevis arises from the lower two-thirds of the lateral surface of the fibula and its tendon, lying in front of that of the peroneus longus behind the lateral malleolus, is inserted to the tubercle of the base of the fifth metatarsal bone.
What is the origin and insertion of peroneus longus?
Origin: (proximal attachments): Head and proximal 1/2 to 2/3 of lateral side of fibula. Insertion: (distal attachments): Crosses plantar surface of foot to attach to lateral sides of medial (1st) cuneiform and 1st metatarsal.
Where do the peroneal longus and peroneal brevis tendons insert?
The superior and inferior peroneal retinacula function to prevent tendon subluxation as they secure the tendons of the peroneus brevis and longus in place at the level of the ankle. The superior peroneal retinaculum covers the peroneal muscle tendons with attachments at the distal fibula and lateral calcaneus.
What is the origin and insertion of peroneus brevis?
Origin: (proximal attachments): Distal 1/3 to 1/2 of lateral side of fibula. Insertion: (distal attachments): Tuberosity on lateral side of 5th metatarsal.
What is the distal attachment of the gastrocnemius muscle?
Posterior calcaneus
Insertion: (distal attachments): Posterior calcaneus via calcaneal tendon.
What is the distal attachment of the flexor digitorum longus?
Flexor digitorum longus muscle
| Origin | Posterior surface of tibia (inferior to soleal line) |
|---|---|
| Insertion | Bases of distal phalanges of digits 2-5 |
| Action | Metatarsophalangeal and interphalangeal joints 2-5: toe flexion Talocrural joint: foot plantar flexion Subtalar joint: foot inversion |
| Innervation | Tibial nerve (L5, S1, S2) |
What is the difference between longus and brevis?
Adductor brevis is “a short muscle that leads something toward the body” and adductor longus is “a long muscle that leads something toward the body”.
What is the origin insertion and action of the flexor hallucis longus?
Flexor hallucis longus muscle
| Origin | (Distal 2/3 of) Posterior surface of fibula, interosseous membrane, posterior intermuscular septum of leg, fascia of tibialis posterior muscle |
|---|---|
| Insertion | Base of distal phalanx of great toe |
| Innervation | Tibial nerve (S2, S3) |
What is the origin of the peroneus longus?
Fibularis (peroneus) longus muscle
| Origin | Head of fibula, proximal 2/3 of lateral surface of fibula, intermuscular septa |
|---|---|
| Insertion | Medial cuneiform bone, metatarsal bone 1 |
| Action | Talocrural joint: Foot plantar flexion; Subtalar joint: Foot eversion; Supports longitudinal and transverse arches of foot |
