Categorize the characteristics of the TIBIA & FIBULA

Groups:

(a) TIBIA

,

(b) FIBULA

• located on the medial side

• weight bearing

• 2nd largest bone in the body

• NON weight bearing bone

• located on the lateral side, slightly posterior

TRUE OR FALSE- The tibia is characterized as a LONG bone.

• TRUE

• FALSE

Proximal end features of the tibia: ​ (a)   and ​ lateral

condyles; ​ (b)   surfaces articulate with the ​ (c)  

• medial
• superior
• femur
• anterior
• posterior
• fibula

Categorize the TIBIAL TUBEROSITY and the ANTERIOR CREST

Groups:

(a) TIBIAL TUBEROSITY

,

(b) ANTERIOR CREST

• located on the anterior surface, just below the condyles

• starts at the tibial tuberosity

• sharp ridge on the anterior surface of the tibial body

• attachment point for muscles

Match the DISTAL TIBIA features

• Palpable landmark at the distal end

• Medial Malleolus

• Slightly movable (amphiarthrotic)

• Fibular Notch

• depression for articulation w/distal fib

• Anterior Tubercle

• Onthe anterolateral surface, overlap fib

• Distal Tibiofibular Joint

Fibula- long, slender, ​ (a)   bone; the head (​ (b)   end) articulates with the tibia's ​ (c)   at the proximal ​ (d)   joint.

• nonweight bearing
• proximal
• lateral condyle
• tibiofibular
• weight bearing
• anterior
• posterior

Categorize the FIBULA features:

Groups:

(a) APEX

,

(b) LATERAL MALLEOLUS

• extends lower than the media malleolus

• distal end, part of the ankle mortise

• cone shaped projection on the lateral, posterior head

1. The knee joint is the ​​ ​ (a)   joint.
