muscle compartments- thigh overview Flashcards
anterior compartment
Boundaries
* Deep Fascia (superficially)
* Medial Intermuscular Septum (posterior/medial)
* Lateral Intermuscular Septum (posterior/lateral)
* Shaft of femur (deep)
Common Action
Knee extension- consistent with nerve derived from posterior division of plexi
Common Innervation
Femoral Nerve
Common blood supply:
Profunda femoris and femoral artery)
Spaces:
* Femoral Triangle
* Adductor Canal
Muscles:
* Rectus Femoris
* Vastsus Lateralis
* Vastus Medialis
* Vastus Intermedius
* Sartorius?
medial compartment
Medial compartment boundaries:
* Deep Fascia (superficially )
* Medial Intermuscular Septum (Anteriorly)
* Shaft of Femur (deep)
Common Action
Hip Abduction - consistent with nerve derived from anterior division of plexus
Innervation:
Obturator Nerve
Blood:
Profunda Femoris
(obturator superiorly)
Muscles
* Adductor Brevis
* Adductor Longus
* Adductor Magnus (adductor part)
* Gracilis
posterior compartment
Posterior compartment
Boundaries:
Deep Fascia (superficially)
Lateral Intermuscular Septum (ant./lat.)
Linea aspera (deep)
Note* there is no structure forming a boundary between medial and posterior compartments: this is an arbitrary boundary between the hamstring and adductor components of Adductor Magnus
Common Action:
Knee Flexion- consistent with nerve derived from anterior division of plexus
Common innervation:
Tibial Nerve
Common blood supply:
Profunda Femoris Artery
(assisted by inferior gluteal)
Spaces:
- Politeal Fossa
Muscles:
* Biceps Femoris (SH+LH)
* Semimembranosus
* Semitendinosus
* Adductor Magnus (Hamstring part)
