UL Flashcards
What makes up the pectoral girdle?
scapula and clavicle
What is the only joint to connect the upper limb to axial skeleton?
sternoclavicular joint
Why is there only one joint between the UL and axial skeleton?
want maximum range of motion
Does the scapula articulate with the axial skeleton?
no
Is the clavicle part of the axial skeleton?
no
What is the ball and socket join of the shoulder?
glenohumeral joint
What type of joint is the elbow?
hinge joint w/ 3 bones
What are the three main areas of transition in the UL?
axilla
cubital fossa
carpal tunnel
What must the vasculature of the UL cross?
must go up and over the 1st rib
Where would you check to see if C6 was damaged?
thumb
Where would you check to see if C7 was damaged?
index finger
Where would you check to see if C8 was damaged?
pinky finger
Where would you check to see if T1 was damaged?
medial forearm
Where would you check to see if T2 was damaged?
axilla
What are the superficial veins of the UL?
cephalic v.
basilic v.
median cubital v.
dorsal venous arch.
What does the cephalic vein drain?
dorsal posterior/later UL
Where does the cephalic vein run?
in deltopectoral groove, pierces deep fascia and goes through clavicular-pectoral triangle
What does the basilic vein drain?
anterior/medial UL
What is the cephalic vein a tributary to?
axillary v.
What is the basilic vein a tributary to?
brachial v.
Where is the median cubital vein?
connects the cephalic and basilic veins in the cubital fossa region
What vein is most used for IVs?
median cubital v.
Why is the dorsal venous arch of the hand important?
it creates medial/later and anterior/posterior anastomoses of all supply to UL
What is the deep fascia of the arm?
brachial fascia
How is the brachial fascia connected to the humerus?
2 septa, medial and lateral
Why is the deep fascia of the arm important?
Divides arm into anterior and posterior compartments
advantage: infection borders
disadvantage: increased pressure can affect circulation
Is the anterior compartment smaller or larger than the posterior compartment in the proximal UL?
smaller
Is the anterior compartment smaller or larger than the posterior compartment in the middle and distal UL?
neither, the compartments are about the same size
What muscles are contained in the anterior compartment?
biceps brachii m.
coracobrachialis m.
brachialis m.
What nerves and vessels are contained in the anterior compartment?
brachial vessels
5 brachial plexus nerves
What are the motor nerves contained in the anterior compartment?
musculocutaneous n.
median n.
ulnar n.
What are the cutaneous nerves contained in the anterior compartment?
medial brachial n.
median antibrachial cutaneous n.
What muscle(s) is contained in the posterior compartment?
triceps brachii m.
3 heads: long, lateral, medial
What nerve is contained in the posterior compartment?
radial n.
What major vessel is contained in the posterior compartment?
deep brachial a.
