The posterior surface of the tibia has a line - the ____ line
soleal line
The margins of the two heads of gastrocnemius form the lateral and medial border of the lower end of the _____ ____
popliteal fossa
The plantaris descends through the leg as a very small tendon and performs ____ ____
plantar flexion of foot and knee
The popliteus unlocks the ___ by
knee
by laterally rotating the femur on the fixed tibia
The flexor _____ longus muscle is partially active during the toe-off phase of walking when the body is propelled forward off the stance leg
The flexor hallicus longus muscles is partially active during the toe-off phase of walking when the body is propelled forward off the stance leg
True or False
FDL is medial to FHL in the leg
True
though they cross in the plantar region of fthe foot
The tibialis posterior muscle originates from the ________ ______ and acts in inversion and plantar flexion of the foot
The tibialis posterior muscle originates from the interosseus membrane and acts in ______ and plantar ____ of the foot
The sural nerve descends _____ along the belly of gastrocnemius
superiorly
The belly of fibularis longus is _____ the belly of fibularis brevis
The belly of fibularis longus is above the belly of fibularis brevis
Which muscle passes through the bony tubercle of the calcaneus?
fibularis longus
What are the four muscles of the anterior compartment of the leg?
tibialis anterior
extensor hallicus longus
extensor digitorum longus
fibularis tertius
The tibialis anterior provides what movements?
Dorsiflexion / inversion
the extensor hallicus longus provides what movements?
extension of big tow and dorsi flexion
The extensor digitorum longus provides what movement?
extension of lateral 4 toes and dorsi flexion
The tibial tuberosity is huge and used for
insertion of patellar tendon (ligament) - quads
Anterior tibia is the most common side for what type of fracture?
compound fracture (open)
The anterior and posterior intermuscula septa create/border the ______ compartment
lateral compartment
All muscles of anterior caompartment of leg pass under the ____ ________
extensor retinaculum
Timothy has a nasty dirty toe is a nmemonic for what
things passing under the extensor retinaculum
From medial
T - Tibialis anterior H - E.Hallicus Longus A - Artery (ant. tib a.) N - Nerve (deep fibula n.) D - E.Digitorum longus T- Fibularis. Terius
The fibularis ____ grooves the bone (lateral mellelus- head of fibula)
brevis
B for Bone
The ______ fibular retinaculum blends with the Extensor retinaculum
the inferior fibular retinaculum blends with the Extensor retinaculum
Fibaris longus passes under to the sole of the foot grooving the _____ bone and inserts on medial ______
Fibaris longus passes under to the sole of the foot grooving the cuboid bone and inserts on medial cunieform = eversion
plantaris is like _____ _____ in upper limb
palmaris longus
Tibialis posterior is responsible for…
Inversion and plantarflexion
What is the mneumonic for the flexor retinaculum of the foot (on the lateral side)
Tom, Dick And Very Naughty Harry (top down)
T - Tibialis posterior D - F. Digitorum Longus A - Artery V - Vein N - Nerve H - F. Hallicus Longus
When tibialis anterior and tibialis posterior contract at the same time, what happens?
Dorsi/plantar flexion is cancelled out
together just pull the medial side = inversion
