Revision: anatomical regions of the body

Question 1

femoral triangle borders

Answer 1

superiorly by inguinal ligament

medially by sartorius

laterally by adductor longus

floor (lat.) by iliopsoas, (med.) by pectineus

roof by fascia lata, subcut. tiss., skin

Question 2

femoral triangle contains

Answer 2

lat -> med:

femoral nerve (and terminal branches)

femoral sheath containing:

• femoral artery and assoc branches
• femoral vein and proximal tributaries
• femoral canal containing deep inguinal lymph nodes and assoc. lymphatic vessels

Question 3

axilla borders

Answer 3

apex: cervico-axillary canal, bounded by 1st rib, clavicle and sup. border of scapula
base: concave skin, SC. tiss and axillary/deep fascia from arm to thoracic wall -> this all forms an axillary wall, the armpit
anteriorly: bounded by Pec. M and m and associated fascia
posteriorly: ant. surface is scapula and subscapularis, inf. surface is Teres M. and Lat. Dorsi
medially: thoracic wall (1-4 ribs and intercostal muscles) and the overlying serratus anterior
laterally: intertubecular groove of humerus

Question 4

axilla contents

Answer 4

axillary artery and branches

axillary veins and tributaries

axillary lymph nodes and lymphatic vessels

These are all embedded in a matrix of axillary fat

It contains large nerves that make up the cords and branches of brachial plexus, proximally ensheathed in a continuation of cervical fascia, the axillary sheath

Question 5

cubital fossa contents

Answer 5

Radial nerve

biceps tendon

brachial artery

median nerve

Question 6

cubital fossa boundaries

Answer 6

superiorly: imaginary line from med -> lat epicondyles of humerus
medially: pronator teres
laterally: brachioradialis
floor: supinator and brachialis
roof: brachial and antebrachial fascia reinforced by bicipital aponeurosis, SC tiss and skin

Question 7

anatomical snuff box boundaries

Answer 7

medially: tendon of EPL
laterally: tendons of EPB and AbPL
proximally: styloid process of radius
base: carpals: scaphoid and trapezium
roof: skin

Question 8

anatomical snuff box contents:

Answer 8

radial artery

the cephalic vein begins here

Question 9

Popliteal fossa borders

Answer 9

Sup-lat: Biceps femoris

Sup-med: Semimembranosus

Inf-lat and -med: lat. and med. heads of gastrocnemius

Roof: skin, subcutaneous tissue fascia

Deep: diverging medial and lateral supracondylar lines of the femur

Question 10

Popliteal fossa contents

Answer 10

Termination of small saphenous vein

Popliteal arteries and veins

Tibial and common fibular nerves

Posterior medial cutaneous nerve of thigh

Popliteal lymph nodes and lymphatic vessels
