Musculoskeletal Flashcards
name the 4 muscles of the superior gluteal region
gluteus maximus
gluteus medius
gluteus minimus
tensor fasica latae
what is the function of the superior muscle group of gluteal region
extensors, abductors, medial rotators of the thigh
what is the specialised movement of the gluteus maximus
lateral extension of the thigh
which nerve innervates the gluteus maximus and name its nerve roots
inferior gluteal nerve - L5, S1
which nerve innervates the gluteus minimus, medius and tensor fascia latae
superior gluteal nerve L4, L5
Trendelenburg’s Gait arises due to damage to which nerve
superior gluteal
name the 4 muscle of the deep gluteal region
piniformis
obturator internus
gemelli
quadratus femoris
what is the function of the deep muscle group of gluteal region
lateral rotators of thigh
hip stabilisation
which nerves innervate the deep muscle of gluteal region
sacral plexus
which structures pass through the greater and lesser sciatic foramen
nerves and blood vessels
which two ligaments form the two foramen in the pelvis
sacrotuberous and sacrospinous ligaments
the sciatic nerve lies inferior to which gluteal muscle
piniformis
what structures does the sciatic nerve supply
posterior thigh, all of leg and foot muscles. most of the skin
the sciatic nerve bifurcates at __ to give __ and __
the mid-thigh to give tibial and common fibular nerves
blood supply to sciatic nerve is via
artery to the sciatic nerve
tibial nerve is more medial/lateral and smaller/larger than the common fibular
medial and larger
the sciatic nerve is the most medial/lateral structure exiting the sciatic foramen
medial
name the three compartments of the thigh
anterior, medial and posterior
name the three compartments of the leg
anterior, lateral and posterior
name the muscles in the anterior compartment of the thigh and their functions
pectineus, iliopsoas, sartorius –> all flexors of thigh
quadriceps femoris –> extensors of the thigh
the muscles in the anterior compartment of the thigh are innervated by the __ nerve
femoral
name the muscles of the medial compartments of the thigh and their function
adductor longus, adductor brevis, adductor magnus, gracilis, obturator externus –> adductors of the thigh
what nerve innvervates the medial compartment of the thigh
obturator nerve
name the muscles of the posterior compartment of the thigh and their function
semitendinosus, semimembranosus, biceps femoris –> flexors and extensors of the thigh. AKA hamstrings
