Anterior and Medial Thigh Flashcards
What are the proximal attachments of the iliopsoas?
Iliac crest and T12-L5 vertebrae
What is the distal attachment of the iliopsoas?
Lesser trochanter of femur
What is the action of the iliopsoas?
Flex hip
What is the nerve supply of the iliopsoas?
Anterior rami of lumbar spinal nerves and femoral nerve
What is the proximal attachment of the sartorius?
ASIS
What is the distal attachment of the sartorius?
Medial surface of proximal tibia
What is the action of the sartorius?
Flexion at hip and knee
What is the nerve supply of the sartorius?
Femoral nerve
What muscles make up the quadriceps femoris?
Rectus femoris
Vastus lateralis
Vastus intermedius
Vastus medius
What are the proximal attachments of the quadriceps muscles?
ASIS - rectus femoris
Shaft of femur - everything else
What is the distal attachment for the quadriceps femoris muscles?
Patella then tibial tuberosity
What is the action of the quadriceps femoris muscles?
Extend knee
Flex hip
What nerve supplies the quadriceps femoris muscles?
Femoral nerve
Outline the anatomy of the knee jerk
Striking of patellar ligament causes sudden stretch of quadriceps producing a reflex contraction of the quadriceps
What are the muscles in the medial thigh known as?
The adductor group
What is the action of the muscles of the medial thigh?
Adduct the thigh at the hip joint
What are the muscles in the medial thigh?
Gracilis
Adductor brevis
Adductor longus
Adductor magnus
What is the most medial muscle of the medial thigh?
Gracilis
Give some anatomical relationships for muscles in the medial thigh
Adductors brevis and longus lie anterior to adductor magnus
Adductor brevis lies superior to adductor longus
What are the proximal attachments of the medial thigh muscles?
Pubis
Ischiopubic ramus
What are the distal attachments of the medial thigh muscles?
Posterior surface of shaft of the femur
What nerves innervate the muscles of the medial thigh?
Obturator nerve innervates all except hamstring part of adductor magnus which is supplied by tibial nerve
Which vein does lymph drainage from superficial structures follow?
Great saphenous vein
Where does lymph from superficial structures drain into?
Superficial inguinal nodes then external iliac nodes
Which vein does lymph drainage from deep structures follow?
Small saphenous vein
Where does lymph from deep structures drain into?
Popliteal lymph nodes then deep lymph nodes then external lymph nodes
