Flashcards in Week 5 Lower Limb- Ach Deck (12):
1

What causes varicose veins?

If the valves of the deep veins become incompetent, blood flow reverses direction toward the superficial veins, causing them to become varicose (tortuous and dilated)

2

What is the saphenous "cut down"?

-in emergency transfusion
-constant location of great saphenous vein
- 1 cm in FRONT of the MEDIAL malleolus

3

What muscles make up the quadriceps femoris? Primary function? Innervation?

Rectus femoris
Vastus lateralis
Vastum intermedium
Vastus medialis
-all innervated by femoral nerve
-primary extensors at knee joint

4

Where do the 4 heads of the quads insert?

They insert onto the tibial tuberosity via the patellar ligament

5

What makes up the femoral triangle? What is located inside the femoral triangle?

inguinal ligament (superior)
adductor longus (medial)
sartorius (lateral)

-femoral nerve, artery, vein, and inguinal lymph nodes

6

What does navel stand for?

Nerve
Artery
Vein
Empty
Lymph nodes
(goes lateral to medial)

7

What artery provides major branches to the head and neck of the femur?

the medial circumflex femoral arteries

8

Describe the adductor canal route and what passes through it?

Starts at apex of femoral triangle, and goes until the adductor hiatus (in the tendon of the adductor magnus)

-canal directly deep to sartorius,

-houses femoral artery and vein, and the saphenous nerve

-delivers vessels to popliteal fossa, where they become popliteal vessels.

9

origins and insertions of inguinal ligament?

anterior superior iliac spine and pubic tubercle

10

What nerve supplies the adductors of the thigh?

obturator nerve
(half adductor magnus is supplied by the sciatic nerve)

11

What does the platellar tendon reflex/ knee jerk test?

The L2-4 spinal cord segments and femoral nerve

12

Describe Osgood-Schlatter diesase

epiphysitis of the tibial tuberosity where the patellar ligament attaches

-pain in area
-usually occurs in adolescents
-aggravated by activity
