JR 101 Final ExamThe LCL originates at the (blank) and inserts on the (blank) - ANS-Lateral femoral
condyle/ fibular head
T/F: the patella serves as a fulcrum for the quadriceps muscles and provides a
mechanical advantage to help the quadriceps function more efficiently - ANS-True
When referring to bone anatomy of the knee, how many bones comprise the knee? -
ANS-4
the hamstring muscle group includes: - ANS-biceps femoris, semitendinosus,
semimebranosus
the knee joint is a modified hinge joint that is also a (blank) joint - ANS-synovial
T/F: the posterior cruciate ligament is extracapsular - ANS-False
avascular necrosis means: - ANS-death of bone related to lack of blood flow
the medial femoral condyle is (blank) and (blank) curved than the lateral condyle -
ANS-larger, more
when we discuss "bone changes in forma and function due to mechanical stresses and
the force of muscular tension placed on it" we are discussing? - ANS-Wolff's law
the ligaments of the knee can be divided into 2 groups -
ANS-extracapsular/intraarticular
a tough band of fibrous tissue that usually connects muscle to bone and is capable of
withstanding tension is known as: - ANS-tendon
how many articulations exist within the knee joint? - ANS-3
the flexible connective tissue found on joint surfaces which allows joint surfaces to slide
against one another is called: - ANS-cartilage
t/f: the primary function of the hamstring muscle group is to flex the knee - ANS-true
,t/F: the primary function of the quadricep is to flex the knee - ANS-false
the main function of cortical bone is to provide: - ANS-strength
the medial collateral ligament is responsible for: - ANS-restraint to the valgus
the largest joint in the human body is: - ANS-the knee
if a patient is laying face up on an operating table: - ANS-supine
if you are standing, and take your index finger and slide it down your thigh until it
contacts the patella, the portion of the patella that you first contact is the: - ANS-base
the main blood supply to the lower leg is the: - ANS-popliteal
the lateral collateral ligament is responsible for: - ANS-restraint to varus
anatomical position denotes the patient standing with: - ANS-arms extended at the
sides/palms facing forward/ toes slightly downward
the fibrous connective tissue that connects bones to other bones is: - ANS-ligaments
the soft type of bone exists in the epiphysis regions of long bones - ANS-cancellous
bone
t/f: the point of origin of a muscle is a location where the muscle can move - ANS-false
if a surgeon commented that a particular femoral condyle was "hypertrophic" the
condyle has: - ANS-increased in size
the anterior cruciate ligament is responsible for: - ANS-restraint to anterior tibial
translation with respect to femur
the posterior cruciate ligament is responsible for - ANS-restraint to posterior tibial
translation with respect to femur
t/F: the two points of attachment for the medial collateral ligament are the distal medial
femoral condyle and the proximal fibular head - ANS-false
, with respect to the degrees of freedom of motion in the knee: how many are there? -
ANS-6
the arcs of flexion in the knee are: - ANS-deep flexion, functional, screw home
the mechanical axis of the lower extremity is determined by drawing a straight line from:
- ANS-the center of the femoral head to the center of the ankle joint
when we refer to the "functional axes" of the knee, we reference the combination of
rotations around what two axes? - ANS-the TEA of the femur combined with the
longitudinal axis of the tibia
the flexion-extension axis closely corresponds to the insertion points of what two
ligamentous soft tissue structures in the knee joint? - ANS-MCL and LCL
the "anatomical" or "clinical" TEA of the knee is an imaginary line that connects: -
ANS-the most prominent parts of the medial and lateral epicondyles
the "surgical" TEA is an imaginary line that connects: - ANS-the medial epicondylar
sulcus with the prominence of the lateral epicondyle
which distal femoral condyle in the knee joint has a sulcus - ANS-medial
Whiteside's Line is: - ANS-perpendicular to the surgical TEA
Whitesides line is also known as - ANS-The trochlear A/P axis
Where is Whitesides line drawn from? - ANS-a line drawn from the deepest part of the
trochlear groove posteriorly to the center of the intercondylar notch
t/f: the normal human knee (not operated on) has a medial pivot - ANS-true
during the screw home arc of motion in the knee, the tibia will internally rotate with
reference to the femur as the knee extends - ANS-false
t/f: since the knee joint requires little assistance from the muscles as it moves through
the screw home arc of motion, the resultant motion is described as "active motion" -
ANS-false
