1

what are the 3 compartments of the thigh

anterior, medial and posterior

2

what muscles are in the anterior compartment of the thigh

pectineus, iliopsoas, sartorius, quadriceps femoris

3

what muscles in the anterior compartment are flexors of the thigh

pectineus, iliopsoas, sartorius

4

what muscles in the anterior compartment are extensors of the leg

quadriceps femoris

5

what are the innervations of the anterior compartment

femoral nerve - pectineus, sartorius, quadriceps femoris, iliacus (of iliopsoas)
except posas major

6

what muscles are in the medial compartment of the thigh

adductor longus, adductor brevis, adductor magnus, gracilis, obturator externus

7

what is the function of the muscles in the medial compartment

adductors of the leg

8

what are the innervations of the medial compartment

obturator nerve
except the hamstring of the adductor magnus (tibial nerve)

9

what muscles are in the posterior compartment of the thigh (ham strings)

semitendinous, semimembranous and biceps femoris

10

what is the function of the muscles in the posterior compartment

extensors of thigh and flexors of the leg

11

what are the innervations of the posterior compartment

tibial division of the sciatic nerve
except short head of biceps femoris - common fibular division

12

what muscle of the medial thigh is the most medial

gracilis

13

what muscle of the medial thigh is the only one to cross both the knee and hip joint

gracilis

14

where does the gracilis insert

superomedial aspect of tibia

15

where do the adductor brevis and longus lie in relation to the adductor magnus and each other

brevis and longus are anterior to magnus
brevus is superior to longus

16

where do the muscles of the medial thigh attach to proximally

pubis, ischiopubic ramis or ischial tuberosity

17

where do the muscles of the medial thigh attach to distally

posterior surface of the shaft of the femur along the linea aspera or adductor tubercle femur

18

where does the iliopsoas muscle attach to

iliac fossa and lumber transverse processes/IV discs proximally, lesser trochanter of the femur distally

19

where does the sartorius muscle attach to

ASIS proximally, medial surface of the proximal tibia distally

20

where does the rectus femoris muscle attach tp

ASIS proximally, patella distally

21

how does the obturator nerve, artery and vein enter the medial thigh

obturator foramen of the hip bone

22

where does the obturator nerve divide and into what branches

at the upper border of the adductor brevis
anterior and posterior branches

23

where is the anterior branch of the obturator nerve located

between the adductor longus (anteriorly) and brevis (posteriorly)

24

what are the sensory innervation of the thigh

anterior cutaneous nerve of the thigh, lateral cutaneous nerve of the thigh, cutaneous branch of the obturator nerve

25

spinal level of anterior cutaneous nerve of the thigh and where it branches from

L2-4
femoral nerve

26

spinal level of lateral cutaneous nerve of the thigh and where it branches from

L2-3
lumbosacral plexus

27

spinal level of cutaneous branch of the obturator nerve

L2-4
