Quiz 1 Jaffe Flashcards
What are the superficial muscles of the butt?
Gluteus Maximus, gluteus medius and minimus, tensor fascia latae
What does the gluteus Maximus supply?
Superior and inferior gluteal muscles
What is the action of the gluteus Maximus
Extensor of the femur, lateral rotation and adduction of femur
What is the innervation of the gluteus maximus
Inferior gluteal nerve L5-S2
What supply’s the gluteus medius and minimus
Superior gluteal vessels
What is the movements of the gluteus medius and minimus
Abduct and medially rotate femur. Maintain level pelvis during gait cycle.
What innervates the gluteus medius and minimus
Superior gluteal nerve L4-S1
What is the movements of the tensor fascia latae
Abduct, flex and medially rotate femur. With the glut max it stabilizes the knee joint.
What innervates the tensor fascia latae
Superior gluteal nerve L4- S1

What are the movements of the iliopsoas muscle
Hip flexion
What are the movements of the sartorius muscle
Flexes, abducts and externally rotates hips and flexes knee
What are the movements of the pectineus muscle
Abducts, flexes and medially rotates hip
What muscles are part of the medial thigh

What supply’s the medial thigh compartment muscles
Obturator artery
What are the movements of the adductor longus, brevis and magnus
Hip adduction
What is the movement of the gracilis muscle
Hip adduction, flexion of the knee, and medially rotates the hip
