What superficial vein ascends ant. to the medial malleolus and empties into the femoral vein
Great saphenous vein
What superficial vein ascends post. to the lateral malleolus and empties into the popliteal vein
Small saphenous vein
Are caricose veins more common in the great or small saphenous vein
Great saphenous vein
In terms of dermatomes; stand, sit, shit = ?
- Stand = S1
- Sit = S3
- Shit = S5
3 main ligaments of the hip joint
- Pubofemoral
- Ileofemoral
- Ischiofemoral
Function of the Ileo and pubo femoral ligaments
- Pubofemoral = Prevents hyperabduction of hip joint
- Ileofemoral = Prevents hyperextension of the hip joint
3 hip flexors
- Iliacus
- Psoas major
- Pectineus
Chief flexor of the thigh
Iliopsoas
Main extensor of the hip
Gluteus maximus
Extensors of the hip
- Gluteus maximus
- Biceps femoris
- Semitendinosus
- Semimembranosus
5 adductors of the hip
- Adductor magnus
- Adductor longus
- Adductor brevis
- Obturator internus
- Gracilis
3 abductors of the hip
- Gluteus medius + minimus
- Piriformis
Which muscles internally rotate the hip
- Gluteus medius + minimus
- Gracilis
Which muscles externally rotate the hip
- Gluteus maximus
- Piriformis
- Obturator internus + externus
- Sup. + inf. gemelli muscles
- Quadratus femoris
Four parts of quadriceps
- Rectus femoris
- Vastas lateralis, medialis and intermedialis
What nerve innervates the muscles of the ant. thigh
Femoral nerve
Action of rectus femoris on hip joint
Flexion
3 actions of the sartorius on the hip joint
- Flexion
- Abduction
- External rotation
(For looking at the sole of your foot)
Medial thigh muscles aka
Adductor group
5 medial thigh muscles and their innervation
- Adductor longus and magnus (Obturator n.)
- Gracilis (Obturator n.)
- Obturator externus (Obturator n.)
- Pictineus (Femoral n.)
What passes through the adductor hiatus
Femoral artery and vein
