Trochanter p551 Moore
a.
Gluteus maximus
T
b.
Pirifornis
F
c.
Obturator internus
F
d.
Superior gemelli
F
e.
Obturator externus
F
9.
Gluteus maximus p551 Moore, p 608NM
a.
is the deepest of the gluteal muscles
F - it is most superficial
b.
is supplied by L5, S1
F - Sort of, by L5, S1, S2 (could be correct too)
c.
medially rotates and extends the hip
F - It does extend the thigh but doesn’t medially rotate
d.
forms the skin crease of the gluteal fold
T
10.
Popliteus p588, 589 Moore, 649NM
a.
does not attach to lateral meniscus
F - It goes from lateral surface of lateral femoral condyle AND
lateral meniscus to posterior surface of tibia superior to soleal line
? p621 Moore
b.
causes lateral rotation of femur on fixed tibia
T - It rotates femur laterally 5 degrees on a fixed tibia to unlock
the joint (also rotates tibia medially when limb is unplanted) p588 Moores
c.
arise from the tibia above the condyles
F - below the condyles
d.
Is part of the capsule of the knee
? – passes through the capsule but is adherent to the capsule p588 Moores
e.
Is supplied by the tibial nerve
T – L4, L5 S1
f.
slopes upwards and medially
F - up and laterally
g.
inserts into the lateral meniscus
T
h.
acts to lock the knee in full extension
F - to unlock
i.
is innervated by a branch of the common peroneal nerve
F - tibial nerve
j.
is a weak flexor of the knee
T - And it unlocks knee and rotates femur 5 degrees on fixed tibia and
rotates tibia on unplanted limbs
k.
intracapsular
F - Sort of half and half since it inserts in lateral meniscus and lateral
femoral condyle in the joint capsule and then emerges from the
capsule and attaches to the tibia medially superior to soleal line
