Upper Limb Facts Flashcards
Anterior (Pectoral) Axillary Nodes
Drains lateral Breasts
Receive 75% of lymph from breasts
Parasternal Nodes
Adjacent to internal thoracic vessels
Drains medial breasts
Receives 25% of lymph from breasts
Goes into apical axillary nodes
The cancer
What pierces clavipectoral fascia
Cephalic Vein
Thoracromial Artery
Lateral Pectoral nerve
What are the borders of the deltopectoral triangle
Superior: clavicle
Lateral: Deltoid
Medial: Pec Major
What are the contents of deltopectoral triangle
Superficial: Cephalic Vein
Deep: Tip of Coracoid process and you can palpate
What are the walls of the axilla
Posterior: Subscapularis, scapula, teres major, insertion of lattismus dorsi
Medial: Ribs4-5, intercostal muscles, serratus anterior
Lateral: Intetbuercular groove of humerous
Anterior: Pec major and Pec Minor
Humeral Nodes
Drains upper limb
Subscapular (posterior) nodes
Drains posterior wall of the axilla
Pectoral (anterior) nodes
Drain anterior wall of axilla, including lateral breast
Central Nodes
Receive lymph from humeral, subscapular and pectoral nodes
Apical Nodes
receive lymph from central nodes
Anatomical Snuff box?
Extensor Pollicis Longus
Abductor Pollicis Longus
Extensor Pollicis Brevis
Content:
Scaphoid & trapezium makes the floor of the snuff box
Radial artery is present
What structures passes through the carpal tunnel?
Flexor digitorum superficilais
Flexor Digitorum Profundus
Flexor Pollicis Longus
Median Nerve
What is the connective tissue that covers the digits?
What do they do?
Fibrous Digital Sheath
It covers synovial sheath, covered tendons.
What do the digital snyovial sheath cover?
They cover the tendons of flexor digitorum superficialis and flexor digitorum profundus.
What is the extensor retinaculum
Transverse thickening of deep fascia
Holds extensor tendons in place
Prevent bowstring into of tendons upon hyperextension of wrist
Covers snyovial sheaths
Triangle of Ausculation
Inferior border: Lattissimus Dorsi
Superior Border: Trapezius
Lateral Border: Rhomboid major
overlies 6th intercostal space,
Floor has no large muscles
Can hear sounds w/ stethoscope
What does the thoracolumbar fascia cover
Covers deep back muscles, which are responsible for extension of back or bilateral extensnon.
Support body weight b/c orientation of collagen fibers
Which vein do you put an IV needle or venipuncture
Medial Cubital vein at the cubital fossa.
What are branches of deep brachial artery
Middle collateral artery
Radial Collateral Artery
Subacromial bursa
Located b/w acromian and supraspinatus tendon & deltoid
Painful arc syndrome
Inflammation of subacromial bursa
Painful zone is 15-130 degrees of abduction
Put needle to aspirate inflammation and reduce pain!!
What initiates abduction of the arm?
Supraspinatous promotes initial 15 degrees
How much degrees do the deltoids allow abduction?
15-120 degrees
What allows abduction all the way above the head that scapula rotates?!!(above 120 degrees)
Trapezius (it rotate that glenoid fossa superolaterally above 120 degrees) and serratus anterior
What is the most common rotator cuff to be injured
Supraspinatous muscle
Quadrangular Space borders
Posterior view: Teres Minor: Superior Surgical neck of humerous: lateral Long head of triceps: medial Teres Major: Inferior
Contents of quadrangular space
Posterior Circumflex Humeral Artery
Axillary Nerve
What is the triangular interval
Passage way for radial nerve and deep artery of the arm to radial groove in posterior arm
Teres Major
Triceps Brachii long head
Triceps brachii lateral head are the borders
What is the thyrocervical trunk
allows anastomoses of the shoulder joint
Branches from the thyrocervical trunk (part of the subclavian artery) unites w/ subscapular artery (3rd part of axillary artery)
Creates bypass when there is a kink in the axillary artery( can happen w/ prolonged arm flexion)
