Neurovascular Structures of the Thigh

Question 1

The neurovascular structures of the anterior aspect of the lower limb enter through the…?

Answer 1

femoral triange. This is seen as the equivalent of the axilla in the upper limb.

Question 2

which structure forms the medial boundary of the femoral triangle?

Answer 2

adductor longus muscle

Question 3

which structure forms the lateral border of the femoral triangle?

Answer 3

sartorius muscle

Question 4

which structure forms the base/superior border of the femoral triangle?

Answer 4

inguinal ligament

Question 5

which muscles form the vast proportion of the floor of the femoral triangle?

Answer 5

pectineus and adductor longus

Question 6

what are the 3 major structures present in the femoral triangle?

Answer 6

1. femoral nerve
2. femoral artery
3. femoral vein

Question 7

describe the femoral sheath

Answer 7

the femoral sheath is a funnel-shaped connective tissue tube which surrounds the proximal parts of femoral vessels (but not the nerve) and creates the femoral canal medial to them, which contains lymphatic vessels.

Question 8

what does the lateral compartment of the femoral sheath contain?

Answer 8

femoral artery

Question 9

what does the intermediate compartment of the femoral sheath contain?

Answer 9

femoral vein

Question 10

what does the medial compartment (femoral canal) of the femoral sheath contain?

Answer 10

fat and lymphatics

Question 11

are femoral hernias more common in males or females?

Answer 11

females

Question 12

The femoral artery begins at the inguinal ligament as a continuation of the?

Answer 12

external iliac artery

Question 13

the femoral artery enters the thigh midway between which two bony surface markings?

Answer 13

• ASIS
• pubic tubercle

Question 14

The femoral vein is the continuation of the blank and passes proximally entering the femoral triangle and becoming the blank as it passes under the inguinal ligament.

Answer 14

The femoral vein is the continuation of the popliteal vein and passes proximally entering the femoral triangle and becoming the external iliac vein as it passes under the inguinal ligament.

Question 15

which two important veins drain into the femoral vein in the femoral triangle?

Answer 15

1. profunda femoris vein
2. greater saphenous

Question 16

which nerve is the largest branch of the lumbar plexus?

Answer 16

femoral nerve

Question 17

what is the adductor canal also called?

Answer 17

Hunter’s canal
Subsartorial canal

Question 18

The adductor canal extends deeper and distal until it reaches an anatomical opening in the blank muscle called the blank.

Answer 18

This extends deeper and distal until it reaches an anatomical opening in the adductor magnus muscle called the adductor hiatus.

Question 19

when does the anterior femoral artery become the posterior popliteal artery?

Answer 19

as it passes through the adductor hiatus of the adductor magnus muscle
