Chapter 6 Quiz Flashcards
What is the anatomical term for the knee cap?
patella
What is the anatomical name for the thigh bone
femur
What is the anatomical name for the major weight-bearing bone of the lower leg?
tibia
The two rounded enlargements of the distal femur care called
medial and lateral condyles
True or false: the tibiofemoral joint is comprised of the medial and lateral condyles of the femur articulating with medial and lateral surfaces of the tibial plateau
true
Provide the name of the movement pair of the knee that accompanies the main movements of flexion-extension when the knee is bent and is the reason the knee is considered a modified hinge joint
internal rotation and external rotation
Provide the name of the ligament that provides medial support to the knee and serves as the primary constraint of valgus stress
medial collateral ligament (MCL)
Provide the name of the ligament that becomes taut during knee flexion versus extension and provides key stability in movements like a plié
posterior cruciate ligament (PCL)
The four muscles that comprise the quadriceps femoris are the rectus femoris, vastus intermedius, vastus lateralis, and …
vastus medialis
Provide the name of the muscle that can unlock the knee to allow flexion to occur
popliteus
True or false: the name of the hamstring muscle that can produce external rotation of the knee is the biceps femoris
true
In a standing knee curl strength exercise, you would be targeting which knee muscle group - knee flexors or knee extensors?
knee flexors
During the out phase of a frappé, which prime mover knee muscle group is being used? Knee flexors or knee extensors?
knee extensors
The anatomical term for the alignment deviation of knock knees is
genu valgum
Would a dancer with marked tibial external rotation be able to turn the feet out or in further relative to the middle of the knee
out
Provide the type of rotation of the femur that occurs toward the end of knee extension with the locking mechanism of the knee
internal rotation
Indicate whether the Q angle will generally produce medial tracking or lateral tracking of the patella
lateral tracking
Distinguish whether patellofemoral compression force is increased with lesser or greater knee flexion
greater
Provide the name of the multijoint muscle that often limits the height of the leg to the front due to active insufficiency
rectus femoris
Provide the type of rotation of the femur that should be limited in the last 30 degrees of knee extension to control hyperextended knees when standing
internal rotation
True or false: knee instability following landing from a jump on one leg in which the dancer felt a popping sensation may likely indicate an anterior cruciate ligament injury
true
Locking of the knee with pain on the medial joint line may likely describe this type of injury:
meniscus tear
