Compartments of the Thigh and Knee Joint Flashcards
What are the three compartments of the thigh?
Anterior, medial, and posterior
The deep fascia of the thigh is called the
Fascia Lata
Acts to facilitate venous return
Fascia Lata
The fascia lata is thickened laterally forming the
Iliotibial tract
Provides support for the knee joint and is a site of attachment for the gluteus maximus and tensor fascia lata muscles
Iliotibial tract/band
The deep fascia extends from the iliotibial tract to the femur creating the
Lateral intermuscular septum
Extends from the deep fascia on the medial aspect of the thigh to the femur
Medial intermuscular septum
The anterior thigh is the hip flexor/knee extensor compartment and is innervated by the
Femoral nerve
What are the 8 anterior thigh muscles?
- ) Psoas major
- ) Illiacus
- ) Tensor Fascia Lata
- ) Sartorius
- ) Rectus femoris
- ) Vastus intermedius
- ) Vastus lateralis
- ) Vastus medialis
Which of the anterior thigh muscles function in HIP FLEXION
Iliopsoas, sartorius, tensor fascia lata, and rectus femoris
Which anterior thigh muscles function in knee extension
Quadriceps femoris
The medial thigh compartment houses the hip adductors and is innervated by the
Obturator nerve
What are the 6 muscles of the medial compartment of the thigh?
Pectineus, adductor longus, adductor brevis, adductor magnus, gracilis, and obturator externus
Which medial thigh muscles function in hip adduction
Pectineaus, adductor longus, adductor brevis, adductor magnus, and Gracilis
Which medial thigh muscles function in hip lateral rotation?
Obturator externus
Which medial thigh muscles function in hip extension?
Hamstring part of the adductor magnus
Which medial thigh muscles function in knee flexion
Gracilis
The posterior compartment is the hip extensor, knee flexor compartment and is innervated by the
Tibial nerve
What are the 5 muscles of the posterior compartment of the thigh?
Semitendinosis, semimembranosis, Biceps femoris (long and short heads), and the hamstring part of the adductor magnus
Which posterior thigh muscles function in hip extension?
Semitendinosus, semimembranosus, aductor magnus, and long head of biceps femoris
Which posterior thigh muscles function in knee flexion?
Semitendinosus, semimembranosus, and the long and short heads of biceps femoris
An invagination of transversalis fascia that is extended into the thigh by the femoral artery, vein, and lymphatics
Femoral sheath
Not contained within the femoral sheath
Femoral nerve
Can occur as loops of bowel that enter the medial most compartment of the femoral sheath, i.e. the femoral canal
Femoral hernias
Femoral hernias are distinguished from inguinal hernias in that they pass posterior to the
Inguinal ligament
A hinge type synovial joint between the femoral condyles and tibial condyles, and the patella and femur
Knee joint
The shape of the articulating surfaces, round femoral condyles, and flat tibial condyles, make the knee joint inherently
Unstable
Two wedges of fibrocartilage that provide a shallow socket for the femoral condyles and divide the joint cavity into two compartments
Menisci
The menisci divide the joint cavity into which two compartments?
Suprameniscal and inframeniscal
Between the femoral condyles and the menisci
Suprameniscal compartment
Between the menisci and tibial condyles
Inframeniscal compartment
