pelvic girdle comprised of

sacrum, coccyx, os coxae

os coxae comprised of

3 fused bones, pubis, ischium, illium

accetabulum

hip socket

accetabulum articulates with

head of femur

accetabulum is made up of

contributions from pubis, ischium, illium

obturator foramen

large foramen, junction of pubis and ischium, membrane covers opening, obturator nerve exits pelvic cavity via foramen origin

superior ramus

upper boundary of obturator foramen

pubic symphysis

2 os coxae bones articulate anteriorly via public symphysis, no bone to bone contact, cartilaginous joint

ischial tuberosity

what you sit on, origin of biceps femoris, semitendinosus, semimembranosus

greater sciatic notch

passage for sciatic N, superior and inferior gluteal A/V, nerves to obturator internus

lesser sciatic notch

allows passage of tendon of obturator internus

head of femur

articulates with acetabulum of os coxae

fovea capitis

depression in head of femur, not covered in articular cartilage, attachment of the head of the femur (ligamentum teres), covered by synovial membrane, stabilizer of joint

neck of femur

connects head of femur to the rest of the bone

greater trochanter of femur

lateral insertion of: gluteus medius, gluteus minimus, obturator internus, gemellus superior, gemellus inferior, piriformis, obturator externus

lesser trochanter of femur

medial insertion of: illiopsoas

intertrochanteric line of femur

extends between both trochanters, separates the shaft from the neck, anterior surface of femur, origin of vastus medialis

intertrochanteric crest

insertion point for quadratus femoris

ischial spine

origin of gemellus superior, insertion of sacrospinous ligament

ischial ramus

origin of obturator externus, part of adductor magnus

linea aspera of femur

insertion point of vastus medialis, vastus lateralis, adductor brevis, adductor longus, adductor magnus, origin of short head of biceps femoris

gluteal tuberosity of femur

insertion of gluteus maximus, ends in linea aspera

lateral condyle of femur

articulates with proximal end of tibia, contributes to knee joint, covered in articular cartilage

medial condyle of femur

articulates with proximal end of tibia, contributes to knee joint, covered in articular cartilage

adductor tubercle of femur

insertion of hamstring component of adductor magnus

intercondylar fossa of femur

separates the lateral medial condyles, on posterior side of femur, walls bear facets for attachment of cruciate ligaments of knee

patellar surface of femur

condyles connected anteriorly via smooth patellar surface, articular surface between femur and patella, patella slides over patellar surface of femur

lateral condyle of tibia

articulates with lateral condyle of femur, contributes to knee joint, lateral meniscus sits upon, attachment point of iliotibial tract

medial condyle of tibia

articulates with medial condyle of femur, contributes to knee joint, medial meniscus sits upon, attachment point of: iliotibial tract

intercondylar eminence of tibia

between medial and lateral condyles of tibia, attachment point of medial and lateral menisci

medial malleolus of tibia

ankle bone, tendons tibialis posterior, flexor digitorum longus, flexor hallucis longus pass around articulates with talus of foot

fibular notch of tibia

articulates with distal end of fibula, attachment site for ligament that unites tibia and fibula

tibial tuberiosity of tibia

insertion point of patallar ligament

patella

sesamoid bone, forms within tendon, quadriceps femoris tendon

base of patella

closest to femur, insertion point of: rectus femoris, vastus lateralis, vastus medialis, vastus intermedius

apex of patella

attachment point of patellar ligament

medial articular facet of patella

articulates with medial condyle of femur

lateral articular facet of patella

articulates with lateral condyle of femur

fibula

lateral to tibia

head of fibula

articulates with tibia below lateral condyle of tibia, origin of extensor digitorum longus, peroneus (fibularis) longus, soleus, insertion of biceps femoris

lateral malleolus of fibula

ankle bone, tendons of peroneus longus and brevis pass around

Talus of the foot

articulates with distal end of tibia, medial malleolus of tibia, lateral malleolus of fibula, ankle joint

calcaneus of foot

heel, hits ground first when walking, articulates superiorly with talus (subtalar joint), articulates anteriorly with cuboid, attachment for achilles tendon
