Medial thigh Flashcards
Muscles of the medial thigh
Adductor brevis Adductor longus Adductor magnus Gracilis Obturator externus (sometimes)
main supply of medial thigh muscles
obturator nerve
2 parts of adductor magnus
adductor - inserts on linea aspera
hamstring - inserts on adductor tubercle
Adductor part of adductor magnus
Origin: Inferior rami of pubis and rami of ischium
Inserts: Linea aspera (femur)
Action: adduct and flexes thigh
Innervation: Obturator nerve
Hamstring part of adductor magnus
Origin: Ischial tuberosity
Insertion: Adductor tubercle (and medial supracondylar line of femur)
Action: Adduct and extend thigh
Innervation: Tibial part of sciatic nerve
Adductor longus
Origin: Pubis
Attach: Broad linea aspera
Actions: Adduction of thigh
Innervation: Obturator nerve
Adductor brevis
Lies between anterior and posterior parts of obturator nerve, under adductor longus
Origin: Pubis body and inferior pubic rami
Insertion: Linea aspera (posterior, proximal to adductor longus)
Actions: Adduction of thigh
Innervation: Obturator nerve
Obturator externus
Most superior
Origin: Obturator foramen
Insertion: Greater trochanter (posterior)
Actions: adduction and lateral rotation of thigh
Innervation: Obturator nerve
Gracilis
Superficial and medial
Origin: Inferior rami and body of pubis
Insert: Medial tibia (between sartorious and semitendonosous)
Actions: adduction of thigh at hip, flexion of leg at knee
Inneration: Obturator nerve
