Pelvic Girdle Checkpoint

What is the name of the hip bone?What are the 3 parts of the hip bone?

Can you identify them on a diagram???

List 3 functions of the pelvic girdleWhat is the name of the “socket” where the head of the femur sits?List 3 differences between the male and female pelvis. Why are these present?


30 bones in eachFemurPatellaTibiaFibulaTarsalsMetatarsalsPhalanges


Longest, strongest heaviest bone in the bodyDiaphysis has a medial bend to bring knees closer to the midline of the body

Femur continued

HeadNeckTrochanterCondylesPatellar Surface


Sesamoid boneDevelops in the tendon of the quadriceps femoris muscleIncreases the leverage of the tendon and maintains the position of the tendon

Patellofemoral stress syndrome

AKA “Runner’s Knee”Patella does not glide up and down between the femoral condyles but rather laterally causing pain.


Shin BoneLarger of 2 lower leg bonesArticulates with femur, fibula and talus

Tibia Continued

Condyle (medial and lateral)

Tibial TuberosityMedial Malleolus

Shin Splints

Soreness or pain along the tibia due to inflammation of the periosteum from the repeated tugging of the attached muscles and tendons. Often the result of walking or running up and down hills.


Parallel and lateral to the tibiaArticulates with the tibia and the talusHead, lateral malleolus

The Foot


7 Ankle BonesPosterior: Talus and CalcaneusAnterior: cuboid, navicular and 3 cuneiform


5 bones make up the instep of the footNumbered I-V


14 in each footHallux (Big Toe) has 2, the rest of the toes have 3

Bones of the Foot

A - TalusB – NavicularC - CuneiformD - CuneiformE – Distal PhalanaxF – Middle PhalanxG – Proximal PhalanxH - MetatarsalI - CuneiformJ - CuboidK - Calcaneous

Arches of the Foot

Transverse and LongitudinalArches enable the foot to support the weight of the body

LOWER LIMB CHECKPOINTanswer these in your notes
