muscles of lower limb Flashcards
muscles of hip flexion
iliopsoas, rectus femoris are the main ones
also pectineus, sartorious and TFL
connections of the psoas major
from T12-L5 vertebrae to the lesser trochanter
connections of the iliacus
iliac fossa to the lesser trochanter
whats the muscles of hip extension
gluteus maximus and somewhat the hamstrings group
whats the connections of the gluteus maximus
the gluteal surface of the iliac to the gluteal tuberosity and the iliotibial tract
what are the muscles of hip abduction
the glutus medius and the gluteus minimums
attachment points of the gluteus medias and gluteus minimums
greater trochanter distally and the gluteal surface proximally
what do the gluteus medias and minimus do during the swing phase
these two muscles contract on the stance side to prevent excessive pelvic tilt during the swing phase on the opposite leg
what two muscles integrate into the iliotibial band
the tensor fascia lata and the gluteus maximus
what muscle group does hip adduction
the medial thigh group
what muscles are in the medial thigh
pectineus, adductor longus, adductor brevis, adductor magnus, gracilis
what msucles do hip rotators
piriformis, gellemus superior, obturator internus, gellemus inferior, quadratis femoris, obturator externus (external)
the anterior fibres of gluteus medias, gluteus minimus (internal)
where are the two attachment points of the adductor magnus
adductor part attaches to the linea aspera.
the hamstrings part attaches to the adductor tubercle
where do all the medial hip rotation muscles attach
the greater trochanter,cause its the gluteus medias and minimus
what muscles do knee extension
quadriceps group. rectus femoris, vasti medialis, vasti intermedius, vasti lateralis
what are the 5 muscles of the anterior thigh compartment
quadriceps plus the sartorious
attachments of the sartorious
strap muscle from anterior superior iliac spine to the pes-anserinus
where do all the quadrieps muscles attach distally
to the quadripes tendon
where do the hamstrings muscles attach
proximally: ST, SM, long head of BF is ishial tuberosity + linea aspera short head BF
distal: medial tibial condyle SM, ST + head fibula BF
what muscle group does knee flexion and hip extension
posterior thigh group
where does the pes anserinus attach
to the medial tibial condyle
common proximal attachment site of the hamstrings group
ishcial tuberosity
what are the anterior leg compartment muscles
tibialis anterior, extensor hallucis longus, extensor digitorum longus
what are the posterior leg compartment muscles
gastrocnemius, soleus, tibialis posterior, FDL, FHL
