Flashcards in Anatomy 3 - lower leg vasculature Deck (17):
1

What is a dermatome?

a unilateral area of skin innervated by sensory fibres of a single spinal nerve

2

What is a myotome?

unilateral muscle mass receiving innervation from fibres conveyed by a single spinal nerve

3

What is a viscerotome?

organ or organ group supplied by specific spinal nerve levels

4

Where does the abdominal aorta bifurcate and what to?

L4 into left and right common iliac arteries

5

When does the external iliac artery become the femoral artery?

inguinal ligament

6

What does the internal iliac artery supply?

pelvic viscera

7

Where does the profunda arise from?

posterolateral aspect of the femoral artery

8

What are the three brainches of the profunda?

1. perforating branches: perforates adductor magnus to supply h/s muscles
2. lateral femoral circumflex: wraps around ant and alt side of femur (greater trochanter)
3. medial femoral circumflex: wraps around posterior femur to supply neck and head of femur as well as adductor muscles

9

Where does the superficial femoral artery travel?

from femoral triangle through the subsartorial canal to the adduct hiatus

10

What does the superficial femoral artery supply?

anterior thigh muscles

11

When does the superficial femoral artery become the popliteal artery?

adductor hiatus

12

What does the popliteal artery branch into?

superior (med and lat) and inferior (med and lat) genicular arteries which supplies the knee joint

13

Anterior tibial artery

supplies the anterior compartment of the leg and travels through the IOM

14

Where does the anterior tibial artery turn into the dorsalis pedis?

anastomoses of the ankle

15

What does the posterior tibial artery supply?

posterior muscles and structures of the lower leg

16

What does the fibular artery supply?

lateral compartment of the leg by running down the posterior compartment (branches off posterior tibial artery)

17

What two arteries branch off the fibular artery?

medial and lateral plantar arteries
