Flashcards in Anatomy of the Lower Limb Deck (45)
Why should adrenaline-containing local anaesthetic not be given near end arteries?
will cause vasoconstriction and thus occlusion to the only blood supply to that area.
carotid pulse is felt...
anterior to the sternocleidomastoid muscle at the upper border of the thyroid cartilage
the brachial artery pulse is felt
medial to the biceps tendon in the cubital fossa
the radial artery pulse is felt...
lateral to the tendon of flexor carpi radialis
the femoral artery pulse is felt...
inferior to the midpoint of the inguinal ligament
the popliteal pulse is felt...
in the popliteal fossa
the posterior tibial pulse is felt...
between the posterior border of the medial malleolus and the achilles tendon
the dorsal pedis pulse is felt...
medial to the tendon extensor hallucis longus distal to the ankle joint
causes of reduced arterial perfusion pressure
LVF, arterial bleed, arterial rupture (aneurysm), occlusion of the lumen, arterial spasm, external occlusion of the artery
causes of increases venous drainage pressure
RVF, DVT, external compression
Superficial/Deep veins tend to occur in NVBs
Superficial/Deep veins are more anatomically predictable
superficial fascia is...
loose connective tissue and fat varying in depth
deep fascia is...
tough, dense connective tissue that is usually white. divides limbs into compartments
deep fascia of the upper limb (4)
pectoral fascia, deltoid fascia, bracial fascia, antebrachial fascia
Deep fascia of the lower limb (3)
fascia lata (thigh), iliotibial tract, crural fascia (leg)
the basilic vein runs...
the basilic vein drains into...where?
the brachial vein at the level of the mid-arm
the cephalic vein runs...
where does the cephallic vein dive deep?
the deltopectoral groove
where does the cephalic vein drain
the axillary vein
where does the axillary vein become the subclavian
lateral border of rib 1
where do the cephalic and basilic vein arise from?
the dorsal venous network
What connects the cephalic and basilic veins in the majority of people?
median cubital vein
what vein in the arm do 20% of people have?
median vein of the forearm which splits to give median cephalic and median basilic vein
where does the great saphenous vein arise from?
dorsal venous arch
where does the great saphenous vein travel?
where does the great saphenous vein drain into and when?
the femoral vein in the femoral triangle
where does the small saphenous vein arise from?
the dorsal venous arch
