Pelvic Girdle and Lower Limb Pelvic Girdle Consist
Pelvic Girdle and Lower Limb
Pelvic Girdle • Consist of – 2 coxae (hipbones) – Pelvis • Sacrum • Coccyx • Pelvic Girdle
Pelvic Girdle • Function – Support the trunk of the body – Provide attachments for lower limbs – Protects urinary bladder – Protects distal end of large intestine – Protects reproductive organs
Coxa – 3 parts Ilium Largest and forms prominence of hip Ischium Ischial Tuberositysupports weight of hip Pubis Symphysis pubis
Pelvic Girdle • 3 parts of the pelvic girdle fuss in acetabulum which receives the head of femur
Pelvic Girdle • Obturator Foramen – between pubis and ischium; largest foramen in skeleton
Lower Limb • Consist of: – Femur – Tibia – Fibula – Ankle and Foot
Lower Limb • Function: – Framework of the thigh leg, ankle and foot
Femur • Longest in body • Head – projects medially in acetabulum • Fovea capitis – (pit) on femoral head; ligaments attachment • Greater trochanter – muscle attachment • Lesser trochanter – muscle attachment
Femur • Lateral condyle – articulates with tibia • Medial condyle – articulates with tibia • Patella – kneecap; articulates with femur
Tibia • • • “Shin bone” Larger of the two leg bones Medial condyles – articulate with femur Lateral condyles – articulate with femur Tibial tuberosity – attachment for patellar ligament • Medial Malleolus- prominence on inner ankle, attachment for ligaments
Fibula • Long, slender bone • Head – articulates with tibia • Lateral malleolus – articulates with ankle
Ankle and Foot • Tarsal Bones (7) – Talus – moves freely where it pins tibia and fibula – Calcaneus – largest, heel bone – Navicular – Cuboid – Lateral cuniform – Medial cuniform – Intermediate cuniform
Ankle and Foot • Metatarsals (5) – Numbered 1 -5 beginning on medial side – Heads of these bones forms the “balls” of feet – Tarsals and metatarsals are bound by ligaments which form arches in foot
Ankle and Foot • Phalanges – Align and articulate with metatarsals – Three phalanges • Proximal • Middle • Distal Except big toe, has no middle phalanx
