Compartments of the thigh Flashcards
What is the role of the anteriror compartmetn of the thigh?
Illiopsosa
sartoroiusu
quadriceops (rectus femoris and 3 vasti muscles)
Hip flexors
and knee extensors
What is the action of sartorius?
Flexion , abduction and lateral rotation at the hip joint
flexion at knee joint
what 4 muscles make up quadriceps femoris? and all attach to the patella bvia the quadrricep tendon
Rectus femoris
vastus lateralis
vastus mediallis
vastus intermeius (cannot see on picture
what is the action of rectus femoris?
flexes the thigh at the hip joint (one quad that does
extends the knee at the leg joint
what muscle is this in the anteriro compartment
vastus intermedius
what nerve innervates the anteriro compartment?
The femoral nerve
(except psoas msucle- ventral rami L1-L3)
what is the cuteneous branch of the femoral nerve call and what does it supply?
saphenous nerve
through adductor canal paasses between sartoris and gracillis
supplies medial aspect of the ankel
trvaels with great spahenous veins
where is the femoral arteyr located
enters femrola trainghle deep top the midpoint of the inguinal ligament, lateral to the femoral vein
becomes the popliteal artery as it tranverse the adductor hiatus in tho the popliteal fossa
what is the venous draimge of the anteromedial part of the thigh
great saphenous vein - empiteis into the femoral vein
what is the role of the posteriro compartment of the thigh?
Extensors of the hip and
flexors of the Knee
what are the muscles of the posteriro compartment
biceps femoris (long and short head)
semitendousus
semimembranosus
wname this muscle
biceps femoris
on the lateral side of the posteriro thigh has 2 heads
name this muscle
Semtendinosus
can see it has a long thin tendon located next to bicep femoris
What muscle is this
semimebranouss
flattneed membransou part
Label this
What is the main innervation of the Posteriro thigh?
sciatic nerev and its main branch (tibial nerve
describe the blood suppl to the posteriro compartmetn of the thigh
inferiro gluteal artery and perforating branches of the porfudna femoris artery
what is the role of the medial compartment of the thigh
adductors of the thigh/ adductros of the hip joint
adductor longus (superifical)
adductor brevis (deep to longus
adductor magnus (deep)
Gracillis
obturator externus
Pectineus (also a flexor of the hip joint)
what is this muscle?
innervation and action?
adductor brevis
obturator nerve
adducts thigh
what is this muscle called
innervation
action
adductor brevis (deep to adductor longus)
obturator nerve
actiomn- adduct thigh
name this deep msucle and its innervation and action
adductor magnus
adduct thigh (obtuaro nerve)
calso has a hamstring part (extends th ethigh- sciatic nerve tibial)
what is this muscle?
innervation and action
Gracillis
adducts the thigh
flexes leg
helps rotate medially too
obturator nerve - innervation
what is this muscle?
obturator extenus
one of the rotaros of the thigh
innervated by the obturator nerve
what is this muscle
Pectinuis
adductor and flexor of the hip
dual nerve supply (obtruator and sciatic nerve)
what is the main innervation and arteyr to the medial compartment of the thigh
Obturator artery (internal iliac
obturator nerve
