Anatomy lower limb- bones

pelvic girdle comprised of
sacrum, coccyx, os coxae
os coxae comprised of
3 fused bones, pubis, ischium, illium
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
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
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
