Answer 1

Ischial tuberosity EXCEPT short head of biceps femoris

Question 2

Common innvervation

Answer 2

tibial division of sciatic nerve EXCEPT short head of biceps femoris

Question 3

Functions

Answer 3

Thigh extension EXCEPT short head of biceps femoris 
Leg flexion (all four)

Question 4

short head of biceps femoris: innervation

Answer 4

common fibular nerve

Question 5

Semitendinosus attachment

Answer 5

ischial tuberosity and medial surface of superior aspect of tibia

Question 6

Pes Anserinus

Answer 6

goose’s foot: gracilis, sartorius, semitendinosus

inserts on anterior medial tibial

Question 7

Semimembranosus

Answer 7

Ischial tuberosity, posterior part of medial condyle
tibial division of sciatic
extension of thigh, flexion of leg

Question 8

Semimembranosus tendon, attachments

Answer 8

distal end divides into two parts

1. medial tibial condyle
2. oblique popliteral ligament

Question 9

Flexion of leg, extension of thigh, and tibial division of sciatic nerve

Answer 9

BICEPS FEMORIS

shorthead and long head

long head: tibial sciatic nerve innervation and ischial insertion

shorthead: common fibular nerve, distal lateral lip of linea aspera.

Question 10

What is the common attachment point for the biceps femoris?

Answer 10

the head of the fibula

Question 11

“hamstring” portion

Answer 11

adductor magnus
ischial tuberosity
tibial division of sciatic nerve
extends thigh

Question 12

Popliteal Fossa: Superomedial boarders

Answer 12

1. Semimembranosus

2. Semitendinosus

Question 13

Popliteal fossa: Superolateral boarders

Answer 13

biceps femoris

Question 14

Popliteal fossa: Inferolateral boarders

Answer 14

Lateral head of gastrocnemius

Question 15

Popliteal fossa: inferomedial boarders

Answer 15

medial head of gastrocnemius

Question 16

Popliteal artery

Answer 16

Continuation of femoral artery

Question 17

When does the popliteal artery become the popliteal artery? Where does it arrive from?

Answer 17

It’s the continuation of the femoral artery

It becomes the popliteal as it passes through the adductor hitatus

Question 18

What does the popliteal artery produce?

Answer 18

genicular branches

Question 19

Genicular branches of the popliteal

Answer 19

Participate in the formation of genicular anastomosis

Question 20

When would the genicular branches of the poplitear artery become significant?

Answer 20

When the knee is flexed too long or if popliteal vessels become occluded or blocked

Question 21

What parts of the popliteal region do the genicular branches supply blood to?

Answer 21

ligaments and articular knee capsule

Question 22

Popliteal termination

Answer 22

ends by dividing into anterior and posterior tibial arteries

Question 23

what forms the popliteal vein

Answer 23

union of anterior and posterior tibial veins

Question 24

Small saphenous vein has what relationship with the popliteal vein

Answer 24

terminates into the popliteal vein

Question 25

Small saphenous vein and popliteal vein become what, and where

Answer 25

the femoral vein after passing through adductor hiatus

Question 26

In the popliteal foss the sciatic nerve divides into the

Answer 26

common fibular and tibial

occurs at superior angel of fossa

Question 27

Peroneal Nerve does what, where, and branches from what

Answer 27

also called common fibular nerve
winds around fibula head and neck
passes superficially to lateral head of gastrocnemius

terminates into deep and superficial branches

Question 28

Sural Nerve

Answer 28

cutaneous nerves of the popliteal fossa

supplies distal superior aspect of leg, lateral aspect of ankle and foot

runs inferiorly with small saphenous vein

Question 29

Sural Nerves: where do the branches come from

Answer 29

Medial sural nerves = tibial

Laterial sural nerves = common fibular nerves
