Answer 16

The vastus intermedialis

Articularis Genu muscle

Question 17

What serves to separate the patellar and tibial surfaces of the femoral condyles?

When the knee is extended it is in the vertical groove

Question 19

Where does the nutrient artery to the femur come from?

Answer 19

Comes from the second perforating artery of the leg.

Question 20

For all bones on the body the nutrient foramen is directed?

Answer 20

Away from the growing side of the bone in the body.

Question 21

Answer 21

the femur undergoes endochondral ossification and has 5 ossification centers.

Question 22

Answer 22

The shaft of the femur is the primary fusion center.

Question 23

What are the surfaces and borders of the patella

Answer 23

Borders are superior, medial and lateral.

Surfaces are anterior and posterior.

Question 24

Where does the patella receive blood supply?

Answer 24

From the genicular arteries that supply the quadriceps tendon.

Artery enters at the nutrient foramen in the lower 1/5th posterior surface.

Question 25

LArgest of the four quadriceps muscle?

Answer 25

Vastus lateralis

Question 26

Which two tendons does the vastus medialis originate from

Answer 26

the adductor longus

adductor magnus

Answer 27

Sartorius

Question 28

Most anterior of adductors

Answer 28

adductor longus

Question 29

aductor brevis originates between

Answer 29

gracillis

obturator externus

Question 30

Sometimes the pectineus has two strata, what nerve supplies the dorsal stratum adn what serves the ventral stratum?

Answer 30

The dorsal stratum is serves by the femoral nerve or accessory obturator.

The obturator nerve supplies the ventral stratum when present.

Question 31

Which hamstring muscle do the biceps femoris long head muscles originate with?

Answer 31

The biceps femoris long head and the semimemranosus muscle both originate together.

Question 32

The short head of the biceps femoris originates between which two muscles?

Answer 32

Originates lateral to the linea aspera between the adductor magnis and the vastus lateralis.
