Medial thigh Flashcards
Actions of the medial thigh
Adduction of hip
Innervation of medial thigh
Obturator nerve (L2-L4)
What is the adductor hiatus
Gap between adductor part and hamstring part of adductor Magnus that allows passage of the femoral artery
What runs through the small perforations of the adductor Magnus (adductor part)
Branches of deep artery of thigh
Origin of adductor part of adductor Magnus
Inferior pubic rami and rami of ischium
Attachment of adductor part of adductor Magnus
Linea aspera of femur
Origin of hamstring part of adductor Magnus
Ischial tuberosity
Attachment of hamstring part of adductor Magnus
Adductor tubercle on distal medial femur
Action of adductor Magnus
Both adduct thigh
Adductor part also flexes thigh
Hamstring part also extends thigh
Innervation of adductor Magnus
Adductor part innervated by obturator nerve
Hamstring part innervated by tibial nerve (L4-S3)
Origin of adductor longus
Superior pubic rami
Attachment of adductor longus
Linea aspera of femur
Action of adductor longus
Adduction and medial rotation of thigh
Origin of adductor brevis
Body of pubis and inferior pubic ramus
Attachment of adductor brevis
Linea aspera on posterior femur, proximal to adductor longus
Origin of obturator externus
Membrane of obturator foramen, superior and inferior pubic rami
Attachment of obturator externus
Greater trochanter (posterior)
Action of obturator externus
Lateral rotation and adduction of thigh
Origin of gracilis
Inferior pubic rami and pubic symphysis
Attachment of gracilis
Medial tibia between tendons of sartorius (anteriorly) and semitendinosus (posteriorly)
Action of gracilis
Adduction of thigh
Flexion of knee
What is groin strain
Strain (tearing) of adductor muscles of thigh
Tearing is usually at proximal part (near bony attachments)
How do groin strains occur
Sports that require extreme stretching
Treatment of groin strain
RICE
Rest, ice, compression, elevation
What are the muscles in the medial thigh
Adductor Magnus, Adductor longus, Adductor brevis, Obturator externus, Gracilis
Where does adductor brevis lie in relation to obturator nerve
Between its anterior and posterior divisions
Where does the obturator externus in relation to femur
Under neck of femur
What muscle is sometimes transplanted into hand/forearm to replace damaged muscle
Gracilis
Action of adductor brevis
Adduction of thigh
