16
Q

What is the function of the muscles in the medial thigh

A

to adduct the thigh

17
Q

name the adductors

A

gracilis

adductor brevis, longus and magnus

18
Q

What are the proximal attachments of the adductors brevis, longus and magnus

A

pubis, ischiopubic ramus or the ischial tuberosity

19
Q

what is the distal attachment of the adductors

A

posterior surface of the shaft of the femur along the linea asperal or the adductor tubercle of the tibia

20
Q

what nerve innervate the medial compartment of the thish

A

obturator

21
Q

what are the roots of the obturator nerve

A

L2-L4

22
Q

which muscle is not supplied bu the obturator nerve in the thigh and what is it supplied by instead

A
adductor magnus (hamstring part) 
tibial nerve
23
Q

Where do lymph vessels following the great saphenous vein drain

A

superficial inguinal nodes - then to external illiac and (some to deep inguinal)

24
Q

Where does lymph following the small saphenous drain

A

popliteal lymph nodes - then to deep inguinal

25
Q

where are the deep inguinal nodes

A

deep to the fascia lata

medial to femoral vein

26
Q

where do the deep inguinal nodes drain

A

external illiac nodes - there fore all lymph in the lower limb ultimately drains to the external illiac nodes

27
Q

What supplies most of the blood to the head of the femur

A

the medial and lateral circumflex arteries (branches of the femoral profunda artery)

28
Q

what makes up the femoral sheath

A

transversalis and iliopsoas fasica from the abdmonimal wall - surround the most proximal part of the femoral artery and vein NOT nerve

29
Q

What gives the sensory innercation to the thigh

A
anterior cutanous (L2-4)
lateral cutaneous (L2-3)
cutaneous branch of obturator (L2-4)
