What is the superior border of the femoral triangle?

A

Inguinal Ligament

2
Q

What is the Lateral border of the femoral triangle?

A

Sartorius

3
Q

What is the medial border of the femoral triangle?

A

Adductor longus

4
Q

What is the floor of the femoral triangle?

A

Iliopsoas and pectineus

5
Q

What is the roof of the femoral triangle?

A

Deep fascia

6
Q

From lateral to medial what are the contents of the femoral triangle?

A

Femoral Nerve
Femoral Artery
Femoral Vein
Lymphatics (Deep inguinal lymph nodes)

7
Q

What envelopes the femoral artery and vein?

A

The femoral sheath

8
Q

What is the femoral sheath made of?

A

Short tube of transversalis and iliopsoas fascia from the adominal

9
Q

Where does the femoral nerve originate?

A

L2,3,4

10
Q

Where is the femoral nerve formed?

A

The Lumbar plexus

11
Q

What is the route of the saphenous nerve?

A

Branches from the femoral nerve to leave the adductor canal distally by passing between sartorius and gracilus

12
Q

What does the saphenous nerve supply?

A

The fascia and skin of the anteromedial aspects of the knee and leg and medial aspect of the foot

13
Q

What is contained in the femoral canal?

A

Deep inguinal lymph nodes

Adipose tissue

14
Q

How do the deep inguinal nodes run?

A

In a chain in the femoral canal medial to the femoral vein

15
Q

What supplies the majority of blood to the head of the femur and through what branches?

A

Medial and lateral circumflex femoral arteries through the retinacular branches

16
Q

What artery do the medial and lateral circumflex femoral arteries come from?

A

Profunda femoris

17
Q

Where does the inguinal ligament run from?

A

ASIS

Pubic tubercle

18
Q

What does the inguinal canal contain in males and females?

A

Males - spermatic cord

Females - round ligament

19
Q

How do the femoral vessels, nerve and iliopsoas exit the lower limb?

A

Deep to the inguinal ligament in the retroinguinal space

20
Q

Where can the inguinal ligament be palpated in dissection?

A

The junction between the external oblique aponeurosis and deep fascia of the thigh (fascia lata)

21
Q

What is the spinal root tested in the knee jerk?

A

L2-4

22
Q

What are the medial thigh muscles?

A

Gracilis

Adductors brevis, longus and magnus

23
Q

The muscles of the medial thigh are innervated by which nerve/

A

Obturator

24
Q

What are the three nerves that provide sensory innvervation of the thigh/

A

The anterior cutaneous nerve of the thigh, which is a branch of the femoral nerve (L2-L4)
The lateral cutaneous nerve of the thigh, which is a branch of the lumbosacral plexus (L2-3)
The cutaneous branch of the obturator nerve (L2-4)
