5.2 Anatomy of the Muscular System Part 9 Flashcards
What is the innervation of the vastus lateralis?
femoral nerve
What is the origin and insertion of the vastus intermedius?
origin = anterior/lateral surfaces of femur
insertion = common tendion of the quadriceps to tibial tuberosity
What is the action of the vastus intermedius?
knee extension
What is the innervation of the vastus intermedius?
femoral nerve
What are the muscles of the adductor group of the medial compartment?
addcutor longus
adductor brevis
adductor magnus
gracilis
pectineus
sartorius
What is the origin and insertion of the adductor longus?
origin = front of pubis
insertion = linea aspera
What is the action of the adductor longus?
adducts and medially rotates thigh
What is the innervation of the adductor longus?
obturator nerve
What is the origin and insertion of the adductor brevis?
origin = superior and inferior rami of the pubis
insertion = medial shaft femur into the upper linea aspera
What is the action of the adductor brevis?
adducts and medially rotates thigh
What is the innervation of the adductor brevis?
obturator nerve
What is the origin and insertion of the adductor magnus?
origin = inferior ramus of pubis
insertion = adductor tuberble and medial condyle of the femur and linea aspera
What is the action of the adductor magnus?
adducts and medially rotates thigh
What is the innervation of the adductor magnus?
obturator nerve
What is the origin and insertion of the gracilis?
origin = lower half of pubic symphysis
insertion = superior shaft of tibia
