Lab - Bones of Pelvic Girdle and Lower Limbs

PELVIC GIRDLE

 

 

Male on left. Female on right.

  

The coxal bone is composed of three bones: ilium, ischium, and pubis.

 

 

 

 

 

FEMUR

Note the head is where the femur articulates with the acetabulum and the condyles are where the femur articulates with the tibia. The femur does NOT articulate with the fibula. The medial condyle of the femur is on the SAME side as the head (a medial structure).

LOWER LEG

Notice how the head of the fibula articulates with the tibia.

TIBIA

There is an indention on the lateral condyle of the posterior tibia where the head of the fibula articulates with the tibia.

 

 FIBULA

This rather unremarkable bone is the non-weight bearing fibula. It is a lateral bone of the leg and this is an ANTERIOR view. A is the head of the fibula (proxiaml epiphysis) and B is the lateral malleolus (distal epiphysis). The tibia and fibula collectively create the feature you think of as your ankle with the medial malleolus of the tibia and the lateral malleolus of the fibula. 

A posterior view of fibula: A is again the head (proximal epiphysis) and B is the lateral malleolus. 

 

TARSAL BONES 

 

  This is the foot with 7 tarsals and 5 metatarsals as well as 14 phalanges. 

A lateral view of the foot: tarsals are short bones and are larger than carpals. A) calcaneus B) talus C) represents the rest which you just need to know as tarsals D) metatarsal E) proximal phalange F) distal phalange. The other toes, like the fingers. have a middle phalanx.
