Thigh Flashcards
what are the 3 compartments of the thigh
anterior, medial and posterior
what muscles are in the anterior compartment of the thigh
pectineus, iliopsoas, sartorius, quadriceps femoris
what muscles in the anterior compartment are flexors of the thigh
pectineus, iliopsoas, sartorius
what muscles in the anterior compartment are extensors of the leg
quadriceps femoris
what are the innervations of the anterior compartment
femoral nerve - pectineus, sartorius, quadriceps femoris, iliacus (of iliopsoas)
except posas major
what muscles are in the medial compartment of the thigh
adductor longus, adductor brevis, adductor magnus, gracilis, obturator externus
what is the function of the muscles in the medial compartment
adductors of the leg
what are the innervations of the medial compartment
obturator nerve
except the hamstring of the adductor magnus (tibial nerve)
what muscles are in the posterior compartment of the thigh (ham strings)
semitendinous, semimembranous and biceps femoris
what is the function of the muscles in the posterior compartment
extensors of thigh and flexors of the leg
what are the innervations of the posterior compartment
tibial division of the sciatic nerve
except short head of biceps femoris - common fibular division
what muscle of the medial thigh is the most medial
gracilis
what muscle of the medial thigh is the only one to cross both the knee and hip joint
gracilis
where does the gracilis insert
superomedial aspect of tibia
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
where do the muscles of the medial thigh attach to proximally
pubis, ischiopubic ramis or ischial tuberosity
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
where does the iliopsoas muscle attach to
iliac fossa and lumber transverse processes/IV discs proximally, lesser trochanter of the femur distally
where does the sartorius muscle attach to
ASIS proximally, medial surface of the proximal tibia distally
where does the rectus femoris muscle attach tp
ASIS proximally, patella distally
how does the obturator nerve, artery and vein enter the medial thigh
obturator foramen of the hip bone
where does the obturator nerve divide and into what branches
at the upper border of the adductor brevis
anterior and posterior branches
where is the anterior branch of the obturator nerve located
between the adductor longus (anteriorly) and brevis (posteriorly)
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
