T/F: the primary function of the quads is to flex the knee
false
T/F: the primary function of the hams is to flex the knee?
True
T/F: the hamstrings originate on the ischium and are posterior to the knee joint?
true
T/F: the hamstrings extend the thigh?
true
The hamstrings muscles include
biceps femoris, semitendinosus and semimembranosous
a commonly used musculoskeletal prefix which means cartilage is
chondro

condyle has
increaed in size
ipsilateral meaning
same side

A surgeon is performing a total knee procedure. When the knee is flexed, he inserts a
long IM rod down the tibial shaft to set up a proximal tibial cutting guide tower. In the
flexed knee, the point of reference that describes the position of the tip of the far end of
the rod down the tibial shaft in relation to the cutting block tower that is placed on the
rod over the tibial eminence is:
distal
the thigh is what region of the body
the region from the hip to the knee
the leg is what region of the body
, the region from the knee to the ankle
the appendicular skeleton is comprised of:
pectoral girdles, the upper limbs, pelvic girdle, lower limbs
a long bone is
cylindrical in shape being longer than it is wide
When we discuss bone changes in form and function due to mechanical stresses and the
force of muscular tension placed on it, we are discussing:
Wolffs Law
the flexible connective tissue found on joint surfaces which allows joint surfaces to slide
against one another is called
cartilage
Acl origin and insertion
originates on the lateral femoral condyle and inserts on the anterior surface of the tibial platue
(AL)
T/F: the point of origin of a muscle is a location where a muscle can move
False
the arcs of flexion in the knee are
screw home, functional and deep flexion
the mechanical axis of the lower extremity is determined by drawing a straight line
from:
the center of the femoral head to the center of the ankle joint
