Fibular Flashcards
What is the head of the FIbula?
Swollen, proximal end of the fibula. It is larger and bulkier than the distal portion of the fibula
Attachment point for: Biceps femoris muscle and the Lateral collateral ligament.
What is the origin site of the Biceps femoris muscle?
Long head - ischial tuberosity (medial region).
Short head – linea aspera, lateral supracondylar ridge of the femur.
What is the insertion site of the Biceps femoris muscle?
Lateral side of the head of the fibula and lateral condyle of the tibia.
What is the Lateral collateral ligament connected from and to?
From the Lateral epicondyle of the femur to the head of the fibula
What is the Styloid process?
Most proximal projection of bone. Forms the posterior protion of the head of the fibula
What is the Interossous crest?
Interosseous crest: is the elevated crest that runs down the medial surface of the shaft.
Attachment point for: Interosseous membrane
What is the proximal articular surface?
Is the round, flat, medially facing articular surface found at the top of the fibula
What is the Nutrient foramen?
Small hole found on the posteromedial surface of the fibula
What is the shaft?
long and thin segment of the bone found between the expanded proximal and distal ends
How many muscles are attached to the Shaft on the anterior surface?
3
How many muscles are attached to the Shaft on the posterior surface?
Tibialis posterior muscle
Soleus muscle
Flexor hallucis longus muscle
How many muscles are attached to the lateral side of the shaft?
2
What is the origin site of the Soleus muscle?
Posterior surface of the tibia (soleal line) and the proximal 1/3 rd posterior surface of the fibula.
What is the insertion site of the Soleus muscle?
Posterior surface of the calcaneus
What is the Lateral malleolus?
the distal/inferior most projection of the fibula.
What is the distal articular surface?
Flat, medially facing, triangular surface.
What is the Malleolar fossa?
Hollow found just below the distal articular surface.
