Anatomy Flashcards
What is superficial fascia mainly composed of?
Loose connective tissue and fat
What provides most of the body’s fat storage?
Superficial fascia
True or false - the superficial fascia varies in depth
True
What does superficial fascia carry?
Superficial blood vessels, cutaneous nerves, lymphatics and sweat glands
What is deep fascia mainly composed of?
Dense connective tissue. It is relatively tough and sheet like
What does the deep fascia cover?
Most of the body deep to skin and superficial fascia
Describe the appearance of deep fascia
White, sometimes glistening
Function of the deep fascia
Divides limbs into compartments
What is deep fascia named according to?
The body region it is located in
Deep fascia in the upper limb
Pectoral fascia, deltoid fascia, brachial fascia, anti-brachial fascia
Deep fascia in the lower limb
Fascia lata - thigh
Iliotibial tract
Crural fascia - bottom of leg
Iliotibial tract
Thickened band of fascia lata at the lateral aspect of the thigh
Where does the iliotibial tract insert onto the ilium and tibia
Inserts onto the ilium superiorly and tibia inferiorly
Intermuscular septa
Thickened sheet of fascia
Muscles within a compartment will have __ actions and __ __ nerve supply
Similar, the same
Clinical importance of deep fascia
Contain and direct the spread of infections/tumours, help to stop the muscle bellies from expanding too far during contraction, and help form part of the muscular venous pump, helping pump blood back to the heart against gravity
Where do the basilic and cephalic veins originate?
The dorsal venous network on dorsum of hand
Houseman’s vein
The section of the cephalic vein on the lateral aspect of the distal forearm. Often readily accessible for sitting a cannula
Describe the course of the cephalic vein
Originates in dorsal venous network on dorsum of hand
Runs anteriorly on the midline of the biceps brachii muscle
As it courses proximally it runs through the deltopectoral groove then dives through deep fascia in the deltopectoral triangle to join the axillary vein
Where does the axillary vein become the subclavian vein?
Lateral border of rib 1
True or false: in 20% of people, the median vein of the forearm bifurcates into the median cephalic vein and median basilic vein
True - these people do not usually have a median cubital vein
Medial cubital vein
Connection of cephalic and basilic vein
Describe the course of the basilic vein
Originates in dorsal venous network on dorsum of hand
Runs proximal on the medial aspect of the anterior forearm
It continues proximally before piercing the deep fascia to become the brachial vein at about mid-arm level
Veins in the cubital fossa
Median cephalic vein, median basilic vein, median vein of the forearm
Where does the great saphenous vein arise?
Medial aspect of the dorsal venous arch (from the foot)
Describe the course of the great saphenous vein
Arises from medial aspect of the dorsal venous arch
Travels proximally up medial aspect of limb
Lies immediately anterior to the medial malleolus
Drains into femoral vein, via the femoral triangle
Happens in anterior proximal thigh just distal to the midpoint of the inguinal ligament
True or false - the great saphenous vein gets smaller as it travels proximally?
False - it gets bigger
Where does the great saphenous vein lie in relation to eh patella?
It lies approximately 1 hands breadth medial to the medial aspect of the patella
