Medial Thigh Flashcards
Adductor Longus Origin
body of pubis inferior to pubic
crest
Adductor Longus Insertion
middle third of linea aspera
of femur
Adductor Longus Innervation
obturator nerve (L2, L3,
L4)
Adductor Longus Action
adducts hip joint
Adductor Longus Arterial Supply
deep femoral and
medial circumflex femoral arteries
Adductor Brevis Origin
body and inferior ramus of
pubis
Adductor Brevis Insertion
pectineal line and
proximal part of linea aspera of
femur
Adductor Brevis Innervation
Obturator nerve (L2,
L3, L4)
Adductor Brevis Action
adduct hip joint and to
some extent flex hip
Adductor Brevis Arterial Supply
deep femoral artery
Adductor Magnus Origin
Adductor part – inferior ramus of pubis,
ramus of ischium
Hamstring part – ischial tuberosity
Adductor Magnus Insertion
Adductor part – gluteal tuberosity,
linea aspera, medial supracondylar line
Hamstring part – adductor tubercle of
femur
Adductor Magnus Innervation
Adductor part – Obturator nerve (L2,
L3, L4)
Hamstring part – tibial part of sciatic nerve
(L4)
Adductor Magnus Action
adducts hip joint; adductor part flexes hip;
hamstring part extends hip
Adductor Magnus Arterial Supply
deep femoral, obturator, and
femoral arteries
Gracilis Origin
body and inferior ramus of
pubis
Gracilis Insertion
superior part of medial
surface of tibia
Gracilis Innervation
obturator nerve (L2,
L3)
Gracilis Action
adducts hip joint; flexes
knee joint and helps it medially
rotate
Gracilis Arterial Supply
deep femoral and
medial circumflex femoral arteries
Obturator Externus Origin
margins of obturator
foramen and obturator
membrane
obturator Externus Insertion
trochanteric fossa of
femur
Obturator Externus Innervation
obturator nerve (L3,
L4)
Obturator Externus Action
laterally rotates hip joint;
pulls head of femur into
acetabulum holding pelvis steady
