Complete the following anatomy review questions.
Foot and Ankle
1.
What are the names of the 7 tarsal bones?
Talus
Calcaneus
Cuboid
Navicular
Lateral cubiform
Intermediate cuniform
Medial cuniform
2.
What bones make up the talocrural joint? What motions occur at the talocrural joint?
Tibia
Fibula
Talus
Plantar Flexion and dorsi flexion occur at this joint
3.
What bones make up the subtalar joint? What motions occur at the subtalar joint?
The talus and calcaneus
The motion is inversion and eversion, abduction/adduction plantar flexion/dorsiflexion
4.
What structure runs the plantar surface of the foot (from the medial calcaneal tubercle to
the metatarsal heads)?
Plantar fascia
5.
What are the three primary ligaments on the lateral side of the ankle?
Anterior talofibular ligament
Calcaneofibular ligament
Posterior talofibular ligament
6.
What is the ligament on the medial side of the ankle?
Deltoid ligament
7.
The styloid process (base) of the fifth metatarsal is the insertion point for which muscle?
Peroneus brevis muscle
Knee
1.
What four bones make up the knee complex?
Femur
Patella
Tibia
Fibula
2.
What tendon is superior to the patella? What tendon is inferior to the patella? What bony
landmark does this tendon insert into?
Superior -Quadriceps tendon
Inferior-Patella tendon
Tibial tubercle bony landmark
3.
What primary ligament is on the lateral side of the knee? What motion/force does it resist?
(ACL) anterior cruciate ligament
Prevents: keeps the tibia from moving forward on the femur
4.
What primary ligament is on the medial side of the knee? What motion/force does it resist?
(PCL) Posterior cruciate ligament
Prevents the tibia from moving posteriorly on the femur
5.
What ligament runs from the lateral condyle of the femur anterior and inferior to the
anterior tibia? What motion/force does it resist?
(LCL) lateral collateral ligament
Restraint against varus forces when knee is between full extension and 30 degree of
flexion and against external rotation of tibia on femur.
6.
What ligament runs from the medial condyle of the femur posterior and inferior to the
posterior tibia? What motion/force does it resist?
(MCL) medial collateral ligament
Resist medially directed shear and rotational forces acting on the knee.
7.
What are the roles (purposes) of the menisci?
Increase joint stability
Shock absorber
Deepens articulation
8.
Which meniscus is smaller and more “O” shaped?
Lateral meniscus
9.
Which meniscus is larger and more “C” shaped?
Medial meniscus
10. What four muscles make up the quadriceps muscles?
Rectus femoris
Vastus medialis
Vastus lateralis
Vastus intermedius
11. What three muscles make up the hamstring muscles?
Biceps Femoris
Semitendinosus
semimembranosus
Pelvis and Sacrum

1.
What three bones make up the pelvis? What is the name where all three bones come
together (the medical term for the hip socket)?
Innominate
Sacrum
Coccyx
All three bone meet at the
acetabulum.
2.
Which quadriceps muscle crosses both the hip and knee joints?
rectus femoris
3.
Where do all three hamstring muscles originate? Which hamstring has a second origin and
where is it?
ischial tuberosity.
Biceps femoris has a second origin at the sacrotuberous ligament
4.
What are the three gluteal muscles? What actions does each muscle perform?
a.
Gluteus maximus -extension of Hip Lateral Rotation
b.
Gluteus medius- Abduction of hip joint
c.
Gluteus minimus-abduction and medial rotation
5.
Which muscle is associate with the sciatic nerve (runs just superficial to the nerve or
sometimes the nerve runs through the muscle)?
Gluteus maximus
