thickened fascia
aponeurosis
deep brachial fascias (4)
medial intermuscular septum, lateral intermuscular septum, anterior/posterior compartments, flexors/extensors
three anterior compartment muscles
coracobrachialis, biceps brachii, brachialis
continuous rubbing of biceps tendon in intertubercular sulcus can cause
rupture of long head of biceps
posterior compartment muscles
triceps, anconeus
tricep that crosses elbow joint
long head
a midhumeral fracture may injure the blank nerve in the radial groove of the humeral shaft
radial
injury to radial nerve in arm results in blank of the blank
paralysis, muscles it innervates/skin
brachial artery branches
(PRUC) profunda brachii, radial, ulnar, common interosseous
artery compressed during blood pressure
brachial artery
superficial veins of arm and are variable
cephalic, basilic, median cubital, dorsal venous arch, palmar venous arch
elbow anastamoses
proximal —> collateral arteries
distal —> recurrent arteries
common site for and procedure of taking blood from the arm
venipuncture in cubital foss
deep veins of brachium are blank and accompany a blank
paired, artery
deep brachial veins begin at blank and blank vein junction
radial, ulnar
deep brachial veins end at blank
axillary vein
nerves of the arm
MAMRU musculocutaneous, axillary, median, radial, ulnar
axillary innervates blank and blank
teres minor, deltoid
axillary cutaneous innervation is at skin over blank of arm
posterolateral
radial nerve innervates muscles of blank
posterior compartment of arm/forearmm
radial nerve cutaneous innervation is at skin over posterior blank
arm,forearm,hand
musculocutaneous nerve innervates all muscles in the blank of the arm
anterior compartment
musculocutaneous nerve innervates skin over blank
lateral antebrachium
median and ulnar nerves do not innervate muscles nor skin of blank
brachium
peripheral nerves contain fibers from multiple blank
spinal roots
boundaries of the cubital fossa that is triangle shaped
brachioradialis, pronator teres
contents of cubital fossa
median nerve, brachial veins, biceps tendon, brachial artery
characteristic sign of radial nerve injury
wrist drop (inability to extend wrist/fingers)
most common vein for taking blood
median cubital vein
superficial structures at cubital fossa
median cubital vein, lateral antebrachial cutaneous nerve, medial antebrachial cutaneous nerve
reconstruction of ucl is aka
tommy john surgery
reconstruction of ucl involves transplanting a blank tendon from the blank forearm or leg
long, contralateral
ulnar collateral ligament parts
anterior band, posterior, oblique
two important ligaments in elbow
radial collateral, ulnar collateral
three olecranon bursae
subtendinous, infratendinous, subcutaneous
median nerve innervates the wrist blank
flexors
ulnar nerve travels posterior to blank
medial epicondyle
proximal radioulnar joint is a blank joint
pivot
avulsion of medial epicondyle can cause blank injury of the blank nerve
traction, ulnar
intrinsic muscles of hand are innervated mostly by blank
ulnar nerve
ulnar collateral ligament parts
anterior band, posterior band, oblique band
three olecranon bursae
subtendinous, intratendinous, subcutaneous
bursae resist blank forces
shear (friction)
avulsion of medial epicondyle is when this ligament pulls a piece off and can affect the blank
UCL, epiphyseal plate
most common bursitis because it is most superficially exposed
subcutaneous olecranon bursitis
