roots and trunks
which part of brachial plexus is at the clavicle?
which part of brachial plexus is infraclavicular?
cords and branches
true or false
Because the brachial plexus is made up of ventral rami of nerves, it is only motor.
plexus roots have all modalities and innervation
what nerve comes off of C5 root of ventral rami?
dorsal scapular nerve
what spinal nerve roots compose the long thoracic nerve?
C5, C6, C7
Where does the Nerve to subclavius and supra scapular nerves come into contact with brachial plexus?
where does supra scapular nerve join the brachial plexus?
where does nerve to subclavius join brachial plexus?
what cords are the anterior compartment?
lateral and medial cord
what nerves branch from medial cord
medial pectoral nerve
medial brachial cutaneous nerve
medial ante brachial nerve
what nerves branch from posterior cord
upper sub scapular nerve
lower sub scapular nerve
which nerve of the major terminal branches compose the anterior compartment
which nerve of the major terminal branches compose the posterior compartment
what nerve is in the anterior compartment of the arm? what is its function?
flexors of elbow joint
what nerve is in the posterior compartment of the arm? what is its function?
extensors of elbow joint
what nerve is in the anterior compartment of the forearm and hand?
ulnar and median nerves
what nerve is in the posterior compartment of the arm?
presentation of this disorder causes upper limb adduction, medially rotated and elbow is extended and wrist is flexed
sensory and motor defects of erbs palsy
sensory: lateral aspect of upper limb
motor: loss of arm abduction, loss of elbow flexion, loss of forearm supination, weakness of wrist extension
