Back 11

popliteal fossa

Front 12

If the femoral artery is occluded at the beginning of the adductor canal, which artery could help provide viability to the leg through collateral circulation?

Back 12

The descending branch of the lateral circumflex femoral artery anastamoses with both the descending genicular branch of the femoral artery as well as the lateral superior genicular branch of the popliteal artery. These connections provide collateral circulation to the knee and leg

Front 13

what muscle must be retracted to expose adductor canal and contents?

Back 13

sartorius

Front 14

what's in the adductor canal?

Back 14

femoral artery, femoral vein, saphenous nerve, and nerve to vastus medialis

Front 15

A ruptured aneurysm in the most proximal portion of the deep femoral artery would result in a hematoma located initially in the

Back 15

deep femoral artery branches from the femoral artery in the femoral triangle. So, if the aneurysm ruptured in the most proximal portion of the deep femoral artery, the hematoma would be in the femoral triangle

Front 16

patient can't flex thigh or extend leg. What n is most likely damaged?

Back 16

quadriceps muscles, innervated by the femoral nerve, are the most important leg extensors. Rectus femoris, a component of the quads, is also a hip flexor

Front 17

MRI reveals a loop of ilium passing inferiorly, posterior to the superior pubic ramus. What type of hernia is this?

Back 17

An obturator hernia is a protrusion of a loop of bowel through the obturator canal

Front 18

what's a lumbar hernia?

Back 18

hernias through the lumbar triangle, which is bordered medially by the latissimus dorsi, laterally by the external abdominal oblique, and inferiorly by the iliac crest.

Front 19

what n lies b/w iliacus and psoas major muscles?

Back 19

FEMORAL N

Front 20

what separates the superficial and deep femoral aa in thigh?

Back 20

ADDUCTOR LONGUS

Front 21

what's the major source of blood to perineum?

Back 21

internal pudendal a

Front 22

If the head of the femur is dislocated postero-medially, compression of which nerve is likely to result?

Back 22

sciatic

Front 23

what passes thru lesser sciatic foramen? Greater sciatic foramen?

Back 23

lesser: obturator internus; greater: piriformis

Front 24

what are the muscles in the hamstring compartment innerv by?

Back 24

all: tibial n; EXCEPT: short head of biceps: common fibular

Front 25

what's in the popliteal fossa?

Back 25

popliteal artery, popliteal vein, common fibular nerve, and tibial nerve

Front 26

what's the deepest struc in popliteal fossa?

Back 26

popliteal a

Front 27

what compartment does the deep femoral a supply?

Back 27

post compartment of thigh

Front 28

what supplies anterior thigh compartment w/ blood?

Back 28

femoral a

Front 29

what supplies medial thigh compartment w/ blood?

Back 29

obturator artery and medial circumflex femoral artery, as well as the deep femoral

Front 30

what supplies gluteal compartment w/ blood?

Back 30

superior and inferior gluteal aa

Front 31

what's most imp muscle for powerfully extending thigh?

Back 31

gluteus maximus

Front 32

which way does piriformis rotate thigh?

Back 32

laterally

Front 33

what's a positive Tredelenburg sign?

Back 33

exhibiting a characteristic hip drop on the uninjured side while standing on the injured side

Front 34

what a supplies lateral leg and ankle?

Back 34

fibular a

Front 35

what internal iliac a branches exit from the greater sciatic foramen superior to the piriformis muscle?

Back 35

superior gluteal a (n, too)

Front 36

what strucs travel thru greater sciatic foramen inferior to piriformis?

Back 36

pudendal nerve, nerve to obturator internus, nerve to quadratus femoris, inferior gluteal artery, posterior femoral cutaneous nerve, inferior gluteal nerve, and sciatic nerve

Front 37

what imp actions do hamstrings do?

Back 37

flex leg; extend thigh

Front 38

what does the popliteal a divide into?

Back 38

anterior and posterior tibial

Front 39

what are imp plantar flexers of foot?

Back 39

gastrocnemius and soleus --> calcaneal tendon ; plantaris also inserts on this tendon and plantar flexes, but it's not a major muscle for this action

Front 40

Back 40

tendon of Tibialis posterior, tendon of flexor Digitorum longus, posterior tibial Artery (and vein), tibial Nerve, and tendon of flexor Hallucis longus. So, T, D, A, N, H equals Tom, Dick, ANd Harry.
