Term
What structures are found in the intervertebral foramen?
Definition
Spinal nerve and dorsal root ganglia
Term
what would occur if you surgically removed the axillary lymph nodes?
Definition
swelling of the arm, difficulty climbing, and difficulty with upward rotation of the scapula
Term
would a ligature on the brachial artery below the profunda brachii still allow blood flow to the rest of the arm?
Definition
yes
Term
where does spinal nerve C8 exit?
Definition
between C7 and T1
Term
what muscle forms the medial boudnary of the axilla?
Definition
serratus anterior
Term
damage to what structure would cause difficulty raising your arm overhead? (winged scapula, maybe?)
Definition
serratus anterior and long thoracic nerve
Term
the subclavian artery is divided into three parts by what muscle?
Definition
anterior scalene
Term
the axillary artery changes its name to the brachial artery at the lateral border of what muscle? (inferior)
Definition
teres major
Term
is the dorsal rami associated with the epimere or hypomere of the myotome?
Definition
epimere
Term
what ligament runs along the spinous processes to the base of the skull?
Definition
ligamentum nuchae
Term
What rib articulates with the sternal angle of louis?
Definition
rib #2
Term
what mation is facilitated by lumbar vertebrae?
Definition
flexion and extension. NOT rotation or lateral flexion
Term
What suboccipital muscle has a distal attachment on the posterior tubercle of the atlas?
Definition
rectus capitus posterior minor
Term
where is the levator scapulae's proximal attachment?
Definition
transverse processes of C1-C4
Term
What is the innervation of the levator scapulae? (or what part of the brachial plexus innervates it?)
Definition
ventral rami of C5
Term
the ribs and vertebrae derive from which part of the somite?
Definition
sclerotome
Term
Describe the pain pathway of a bee string on your superior lateral arm.
Definition
superior trunk --> C5 ventral rami --> spinal nerve --> dorsal root --> dorsal horn
Term
what are the serratus anterior's attachments, and what motion of the scapula does it help?
Definition
??????????? upward rotation of the scapula
Term
what is the most likely arterial supply to the pec major?
Definition
thoracoacromial trunk - pectoral branch
Term
is the clavicle endochondrally or intramembranously formed?
Definition
the appendicular skeleton is formed endochondrally, while the axial skeleton is formed intramembranously. THE CLAVICLE IS THE ONE EXCEPTION. so even though it is part of the appendicular skeleton, it is formed intramembranously
Term
What 3 joints are involved in the scapulohumeral rhythm?
Definition
glenohumeral, scapulothoracic, and sternoclavicular (saddle joint).
Term
does the levator scapulae get its arterial supply from the subclavian or axillary artery?
Definition
subclavian
Term
are the erector spinae muscles innervated by ventral or dorsal rami?
Definition
dorsal rami
Term
What is the arterial supply to the latissimus dorsi?
Definition
thoracodorsal artery
Term
where do the obliqus capitus inferior and rectus capitus posterior major attach?
Definition
C2 spinous process
Term
Is the axillary artery involved in anastamosis of the scapula?
Definition
YES. Bonus:what is an anastamosis?
Term
Where does the supraclavicular nerve arise? which part of the brachial plexus does it arise from?
Definition
ventral rami of C5, C6, and C7
Term
From what part of the brachial plexus does the musculocutaneous nerve arise?
Definition
lateral cord
Term
Is the median nerve formed from anterior or posterior divisions of the brachial plexus?
Definition
anterior
Term

Definition
axillary vein
Term
What fascia does the cephalic vein pierce?
Definition
claviopectoral fascia
Term
Where does the dura mater end?
Definition
S2
Term
What spinal nerve segment innervates the outside of the thumb (dermatomes)?
Definition
C6
Term
Through which TRUNK of the brachial plexus do GSA fibers travel to reach the outside of the thumb?
Definition
superior trunk (upper trunk)
Term
What actions does contraction of the longissimus thoracis cause?
Definition
bilaterally extends the spine, unilaterally rotates to the OPPOSITE side.
