|
What is the ligamentum nuchae?
|
Extension of supraspinus ligament, extends from the occipital protuberance, and attaches to short processes of C3-7
|
|
|
What forms the triangle of auscultation?
|
Medial - inferior trapezius
Lateral - vertebral border of scapula Inferior - superior border of latissimus dorsi |
|
|
What are the borders of the lumbar triangle?
|
Medial- lateral border of latissimus dorsi
Lateral: External oblique Inferior: iliac crest |
|
|
What is an aponeurosis?
|
A grouping of fascia
|
|
|
Thoracolumbar fascia - function of superficial and deep?
|
Superficial distal attachment of latissimus dorsi, covers deep spinal m
Deep: Separates deep spinal mm from abdominal wall |
|
|
What is CN XI and where does it arise from and what does it supply?
|
Spinal accessory, C3-4 nerve roots, supplies trapezius
|
|
|
Where does the dorsal scapular nerve arise and what does it supply?
|
C5, levator scapula, rhomboid major and minor mm.
|
|
|
Where does the thoracodorsal nerve arise and what does it supply?
|
C6-8 supplies latissimus dorsi
|
|
|
What do the intercostal nerves supply?

|
|
What does the superficial branch of the transverse cervical a. supply? what about the deep branch?
|
Superficial- trapezius
Deep - levator scapulae and rhomboid mm |
|
|
Where does the transverse cervical a. arise from?
|
The thyrocervical trunk from the subclavian
|
|
|
What if the transverse cervical a. does not bifurcate?
|
Called superficial cervical a. and only supplies trapezius, and a separate artery will arise from the subclavian called the descending scapular artery to supply the levator scapulae and rhomboid m.
|
|
|
What does the thoracodorsal a branch from and what does it travel with and to what?
|
3rd part of the axilary a. travels with thoracodorsal n. to latissimus dorsi m.

|
Where does the trapezius insert?
|
Spine of the scapula, acromion and lateral 1/3 of clavicle
|
|
|
What does the trapezius do?
upper? lower? |
Adducts and rotates scapula
upper: elevates scapula Lower: depresses scapula |
