Anterior and Medial Thigh Flashcards
innervation of quadriceps femurs?
femoral n.
functions of quadriceps femoris?
vasti extend leg, rectus extends leg and flexes thigh (assists in flexion of the hip), chief extensors
where do the quads insert?
tibial tuberosity
primary bursa of the knee?
suprpatellar pouch/bursa
attachments of the pectineus?
origin: pecten line of pubis
insertion: pectineal line of femora (inferior to the lesser trochanter)
innervation of pectineus?
femoral n (occasionally a branch of the obturator n.)
function of pectinous?
adduct and flex thigh
secondary function of medial thigh (ADDuctor) muscles?
to flex the thigh, external rotation
where to adductors insert?
posterior femur
attachments of adductor longs?
body of pubis (inferior to pubic crest)
middle 1/3 of linea aspera
innervation of adductor longs?
obturator n.
functions of adductor longus?
adducts and flexes thigh
what separates adductor magnus portions? what are the portions:
adductor and quadriceps portions; adductor hiatus
what is unique about gracilis?
only adductor to cross knee joint
attachments of gracilis?
pubis body and inferior ramus
superior part of medial surface of tibia (part of pes anserinus)
innervation of gracilis?
obturator n.
functions of gracilis?
adduct thigh, flex and medially rotate leg
where does adductor brevis lie in relation to pectinous and adductor longs?
deep
attachments of adductor brevis?
pubis body and inferior ramus and proximal linea aspera
functions of adductor brevis?
adducts and flexes thigh
how does groin pull occur?
strain, stretching, and probably some tearing of proximal attachments of thigh adductor/flexor muscles
where is obturator externus in relation to pectinous?
deep
attachments of obturator externus?
external margins of obturator foramen and trochanteric fossa
innervation of obturator externus?
obturator n.
origins of adductor magnus?
hamstring part: ischial tuberosity
adductor part: ischiopubic ramus
insertions of adductor magnus?
hamstring: adductor tubercle (medial epicondyle)
adductor: gluteal tuberosity, linea aspera, medial supercondylar line
innervations of adductor magnus?
adductor: obturator n.
hamstring: tibial division of sciatic n
functions of adductor magnus?
adductor: adducts and flexes thigh
hamstring: adducts and extends thigh
what is Hilton’s law?
joint is innervated by same nerves that supply the muscles that move the joint and supply the skin over the joint
main blood supply to thigh?
deep femoral a.
what is the posterior compartment function?
flexion
what is the primary innervation of posterior compartment?
sciatic n.
what is the primary purpose of anterior compartment?
extension
what is the primary innervation of the anterior compartment?
femoral n.
primary innervation of medial thigh?
obturator n.
what is the primary purpose of the medial thigh?
adduction
blood supply to anteriomedial thigh?
profundus femoris
what augments profundus femurs?
femoral a. and obturator a.
obturator a. primarily supplies
deep adductors
