Lower Limbs Flashcards
What is the nerve of the anterior lateral leg
The deep fibular nerve
L5 to S1
What nerve innovates the fibularis longus and fibularis brevis
Superficial femoral nerve
L5 to S2
What are the flexors of the hip
Iliopsoas (main flex - Psoas and illiacus)
Rectus femoris
Sartorius
What are the extensors of the hip
Hamstrings (biceps femoris, semi membranous and tendinous)
Gluteus maximus
What are the abductors of the hip
Gluteus medius and Minimus
Tensor fascia latae
Sartorius
What muscles Medially rotate the hip
Gluteus medius and minimus
What muscles rotate the hip laterally
(Also abductors)
Obturator internus
Gemelli
Piriformis
Gluteus maximus
Quadratus femoris
Sartorius
What are the muscles that adduct the hip
Adductor Magnus, brevis and longus (medial thigh)
Gracialiis
Obturator externus
What muscles flex the knee
Hamstrings
Gracialiis
Sartorius
Gastrocnemius
What muscles extend the knee
Quadriceps femoris
What muscles rotate are the knee Medially
Semitendinous
Semimembranous
Sartorius
What muscles rotate the knee laterally
Biceps femoris
What muscles plantar flex the ankle (posterior)
Gastrocnemius
Soleus
Tibialis posterior
Flexor digitorium Longus
Flexor hallicus longus
What muscles dorsi flex the ankle (anterior)
Tibialis anterior
Extensor digitorium longus
Extensor hallicus longus
Fibularis Teritus
What nerves go to the anterior, medial and posterior compartments
Medial - obturator nerve (aDductors)
Anterior - femoral nerve (extensors)
Posterior - sciatic nerve (flexors)
What are the hamstrings of the posterior compartments
Biceps femoris
Semimembranous
Semitendinous
What nerve would supply the lateral aspect of the thigh
The lateral femoral cutaneous nerve
What nerve would supply the pectineus
The obturator and the femoral nerves
Why is the pectineus considered to be mainly in the anterior compartment
Would be a flexor of the knee
Why can the pectineus be considered to be in the medial compartment
Medially rotates
aDducts
What nerve innovates the hamstring part of the Adductor Magnus
The sciatic nerve
(Goes to the posterior)
Where is the palpatable area for the Great saphenous vein
1cm anterior of the medial malleolus
What veins make up the great saphenous vein
Dorsal venous arch
The Dorsal vein of the great toe
What muscles would attach to the Pes Anserinus
Say : Sartorius
Grace : Gracialiis
before
Tea : s.Tendinous
What nerve does the femoral nerve become as it goes through the adductor Canal (hiatus)
The saphenous nerve (to the leg)
What are the boundaries of the femoral canal
Lateral : septum between femoral vein and canal
Posterior : pectineus
Medial : lacunar ligament
Anterior : inguinal ligament
What are the boundary’s of the adductor Canal (hiatus)
Laterally and anteriorly : vastus medialis
Posteriorly : adductor longus and Magnus
Anteriorly and Medially : sartorius
Where does the medial and the lateral vastus attach to
The medial and the lateral patellar retinacula
Why would the rectus femoris be a flexor
Would attach above the hip joint so would be a flexor
What is the intermuscular septae
Connective tissue that would come from the deep fascia
separates the compartments of the thigh
What fascia would cover the saphenous opening
Cribiform fascia
(Comes from blending of the membranous scarpas fascia and deep fascia)
What are all the functions of the sartorius muscle (anterior)
Knee : flexes and Medially rotates
Hip : flexes, abducts, laterally rotates
What muscles would be in the medial aspect of the thigh
(The adductors)
Adductor Magnus
Adductor brevis
Adductor longus
Obturator externals
Gracialiis
Where does the tibial nerve and the common peroneal nerve branch from
The sciatic nerve
What is the main blood supply to the neck of the femur
The medial femoral circumflex artery
Where does the superior gluteal nerve pass through
The greater sciatic foremen
What nerve would pass through the lesser sciatic foramen
Pudendal nerve
What nerve innovates the short head of the biceps femoris
Common peroneal branch of the sciatic nerve
What nerve innovates the long head of the biceps femoris
The tibial branch of the sciatic nerve
