Tibia Flashcards
What does the tibia sit in between?
Femur and foot
Where does it sit in relaton to the fibula?
Medially
What does the tibia carry?
All of the bodies weight
What and where does the tibia articulate?
With the femur at the condyle
With the talus at the posterior surface
With the fibula at the facet for the fibula (proximal laterla) and the fibular notch
Where do the tubercles sit?
On the intercondylar eminence
What is the tibial plateau?
The flat surface of the tibia
Where does the top of the tibial plateau sit?
On the medial and lateral condyles
Where is the tuberosity?
At the front of the tibia
Is the anterior border/crest sharp?
Yes
What direction does the nutrient foramen point?
Distally
What surface is slightly convex?
Subcutaneous/medial surface
What is the origin and insertion of biceps femoris?
Origin: linea aspera, lateral supracondylar ridge of femur, ischial tuberosity
Insertion: lateral condyle of tibia (lateral head of fibula too)
What movement does biceps femoris produce?
Knee flexion/rotation and hip extension
What is the origin and insertion of semimembranosus?
Origin: ischial tuberosity
Insertion: posterior surface of medial condyle of tibia
What movement does semimebranosis produce?
Knee flexion/rotation and hip extension
What is the origin and insertion of of soleus?
Origin: soleal/popliteal line (also from upper posterior fibula)
Insertion: posterior calcaneous via Achilles
What movement does soleus produce?
plantar flexion of foot
What is the origin and insertion of popliteus?
Origin: lateral surface of lateral condyle of femur
Insertion: soleal/popliteal line
What movement does popliteus produce?
Medial rotation and flexion of leg
What else can gastrocnemius and soleus be called together?
Triceps surae
What is the origin and insertion of sartorius?
Origin: ASIS
Insertion: upper medial shaft of tibia
What movement does sartorius produce?
Flexion, abduction and rotation of hip
Where does tibialis anterior originate and insert?
Origin: lateral condyle and upper half of lateral shaft of tibia
Insertion: cuneiform and 1st metatarsal
What movement does tibialis anterior produce?
dorsiflexion, supination/inversion of foot
What is tibial squatting facets?
A non metric trait caused by squatting
What is platycnemia?
A non metric trait which flattens tibia in the mediolateral position
What is tibial bowing?
A non metric trait that affects the shaft
