Unit One Suferficial Structures Flashcards
What fascia forms the floor of the axilla
Axillary fascia
Pectoral fascia is continuous with what other fascia
Abdominal wall fascia
The posterior axioappendicular muscles have how many muscles
4
What muscle forms the anterior wall and inferior border of the axilla
Pectoralis major
How do you test the clavicular head of pectoralis major
Abduct arm 90 degrees, move arm anteriorly against resistance
Is fascia continuous
Yes but is named differently due the region the fascia is located in
What muscle forms the inferior border of the deltopectoral groove that contains the cephalic vein
Pectoralis major
Pectoral fascia leaves the lateral border of the pectoralis to become what fascia
Axillary fascia
Purpose of medial and lateral inter muscular septa in the upper arm
Separates the arm into the anterior(flexor) and posterior (extensor) compartments
What septa is present in the upper arm of the fascia
Medial and lateral inter muscular septa
Symptoms of compartment syndrome
Pain, weakness and swelling
What muscles are the anterior axioappendicular muscles
Pectoralis major, minor, subclavius and serratus anterior
UE lymphedema may result from
Metastatic involvement of proximal brachial nodes or due to its treatment
The calvipectoral fascia descends from
Clavicle
The cephalic veins forms on what side and from what
Radial side of venous plexus
How many muscles in the anterior axioappendicular muscles
4
What are the three distinct groups of shoulder muscles
Anterior axioappendicular muscles, posterior axioappendicular muscles, and scapulohumeral muscles
Thumb contains what cutaneous innervation origin
C6
What penetrates through the clavipectoral fascia
Cephalic vein, pectoral branch of the thoracromial artery, lateral pectoral nerve and lymphatics (remember CALL)
What muscle forms the anterior wall of the axilla deep to the pectoralis major
Pectoralis minor
What muscles are surrounded by the scapular fascia
Supraspinatus, infraspinatusl, and subscapularis
What is the test of the serratus anterior muscle
Push against the wall, weakness results in winging of the scapula
What septa is present in the forearm
Interosseous membrane and lateral intermuscular septa
Superficial and deep veins communicate via
Perforating veins
What muscle lies anterior to the clavipectoral fascia
Pectoralis major
When the basilic vein breaks through the fascia it then dives down deep to join what
The brachial vein to form the axillary vein
What fascia surrounds the arm
Brachial fascia
What are the nodes found in the upper limb
Cubital, humeral, subscapular and axillary
What muscle is located along lateral thorax, forms the medial wall of the axilla
Serratus anterior
The basilic vein courses on
The medial aspect of the forearm and arm
Intervention of compartment syndrome
RICE, fasciotomy to avoid myonecrosis
Can the heads on the pectoralis major act independently
Yes
The clavipectoral fascia surrounds what muscle
Subvclavius muscle and pectoralis minor
What occurs if you have a long thoracic nerve injury
Winging and inability to raise the arm past horizontal due to inability to rotate the glenoid
Anterior axioappendicular muscles move what
The pectoral girdle
What is the most powerful muscle of the pectoral girdle
Serratus anterior
3rd digit cutaneous innervation origin is
C7
Where does the brachial fascia attaches inferiorly
Epicodyles and olecranon
How many muscles in the scapulohumeral muscles
6
The cephalic vein crosses the arm through what groove
Delto-pectoral groove
Cephalic vein courses
Proximally on the lateral arm
The median cubital vein crosses what fossa
Antebrachial fossa
Pectoralis major origin contains what two head
Clavicular head and sternocostal head
The posterior axioappendicular muscles attach the
Upper limb to the skeleton of the trunk
Deltoid contains what innervation origin
C5
What muscle attaches to the whole length of the medial scapula
Serratus anterior
The cephalic vein pierces what fascia
Clavipectoral fascia
Sternal head of pec major testing
Abduct arm 90 degrees, adduct arm against resistance
What muscle is found on the inferior surface of the clavicle to the first rib
Subclavius
The basilic vein begins on what of what
Ulnar side of venous plexus
Pectoral fascia surrounds what
Pectoralis major muscle
The lower clavipectoral fascia forms what
Suspensory ligament of the axilla
Purpose of the interosseous membrane and the lateral intermuscular septa in the forearm
Isolate an anterior and posterior compartment in the forearm
The cephalic veins joins what vein after piercing the fascia
Axillary vein
5th digit cutaneous innervation origin is
C8
The basilic vein pierces what fascia
Brachial fascia
Function of suspensory ligament of the axilla
Pulls the axillary fascia taught when the UE is abducted
Compartment syndrome is caused by
Injury or procedure which causes bleeding or edema within the compartment, muscle tear causing bleeding, over use injury causing swelling, inappropriate casting/ swelling
The scapular fascia surrounds muscles that originate where
Surface of the scapula
Causes of lymphedema
Breast cancer, trauma, infection or decreased mobility
The scapulohumeral muscles act on the
Glenohumeral joint
What is fascia
A sheet of fibrous tissue that envelopes the body beneath the skin and or encloses muscles and groups of muscles
The median cubital vein joins what two veins
Cephalic and basilic vein
Veins begin where
In the dorsal venous plexus of the hand
What fascia is present in the forearm
Antebrachial fascia
