Question 7

Femoral Triangle
Borders:
Superior
Medial
Lateral
Floor

Answer 7

Superior: inguinal ligament
Medial: adductor Longus
Lateral: sartorius
Floor
Adductor longus and pectineus

Question 8

Femoral triangle
Contents
NAVL

Answer 8

Femoral Nerve
Femoral Artery
Femoral Vein
Femoral Lymphatic canal

Good for femoral pulse and is the site for the insertion of catheter and angiography

Question 9

Femoral sheath

What does it surround
Continuation of…

Answer 9

Surrounds the femoral artery, vein, and canal and NOT the femoral nerve
Is a continuation of the transversalis fascia

Question 10

Femoral Canal

Contains what

Answer 10

Contains lymph vessels that drain the lower limb that drain to external iliac nodes in abdomen. Open superiority to the abdomen and the opening is called the femoral ring

Question 11

Femoral hernia

Answer 11

Femoral ring is the point of potential weakness in the abdominal wall: a loop of bowel can protrude into the femoral canal and become strangulated (Females)

Question 12

Inguinal Hernia

Answer 12

Differentiated from femoral hernias by the location of the neck of the hernia. Inguinal herinia neck is located above the inguinal ligament

Question 13

Arterial Supply

Flow down the leg and boundary of each

Answer 13

External iliac–>inguinal ligament–>Femoral Artery, goes ant first and then post bc of medial rotation @ development–>adductor hiatus–>popliteal artery

Question 14

The popliteal artery. Divides into what

Answer 14

Anterior and posterior tibial arteries

Question 15

Which tibial artery is the main blood supply to the foot?

Answer 15

Posterior tibial artery

Question 16

Where are the anastomoses in the lower body?

Which joints

Answer 16

Cruciate anastomoses at the hip and genicular anastomoses at the hip

Question 17

Describe the passage of the femoral artery through the leg

Answer 17

1st, passes medial in the anterior thigh and deep to the sartorius in a. Space called the subsartorial canal. 2nd, passes posteriorly though an opening in the adductor magnus muscle called the adductor hiatus. 3rd, once this happens the femoral artery becomes the popliteal artery on the posterior side of the knee

Question 18

Where is the profunda femoris found and what does it supply

Answer 18

Largest branch of the femoral artery, arises posteriory in the femoral triangle, and passes between the pectineus and adductor longus branches

Question 19

Medial femoral circumflex supplies and where it is located

Answer 19

Passes directly posteriorly between pectineus and iliopsoas and provides the majority of the blood supply for the head of the femur

Question 20

Lateral femoral circumflex passage and supply

Answer 20

Passes laterally, deep to rectus femoris. Supplies lateral side of thigh, neck of femur. Has descending branch that is part of the genicular anastomoses at the knee joint

Question 21

Ischemic necrosis

Answer 21

Falling in the elderly can damage the medial circumflex artery due to the fracturing of the neck of the femur. This head receives blood supply from the medial femoral circumflex artery and the obturator. If the obturator blood supply is inefficient the head of the femur can necrosis and require hip replacement.

Question 22

Perforating arteries of the femoral artery.

Answer 22

Provide blood supply to the posterior compartment of the thigh. They erforate the adductor magnus muscle deep adjacent to the femur.

Question 23

Composition of the cruciate anastomoses 
Superior
Medial 
Lateral
Inferior

Answer 23

Superior: medial femoral circumflex (from internal iliac)
Medial: medial femoral circumflex (profunda femoris)
Lateral: lateral femoral circumflex (profunda femoris)
Inferior: first perforating artery (profunda femoris)

Question 24

Femoral artery ligation

Answer 24

Can be lighted due to the cruciate anastomoses which will maintain blood supply to the hip joint
