brachial plexus Flashcards
what nerve roots give rise to the superior trunk
C5 and C6
what nerve roots give rise to the middle trunk
C7
what nerve roots give rise to the inferior trunk
C8, T1
what makes up the posterior cord
the posterior divisions of the superior, middle and inferior trunks
what makes up the lateral cord
the anterior divisions of the superficial and the middle trunk
what makes up the medial cord
the anterior division of the inferior trunk
what does the medial cord give rise to
the ulnar nerve and the median nerve
what does the lateral cord give rise to
the musculocutaneous nerve and the median nerve
what does the posterior cord give rise to
the radial nerve and the axillary nerve
nerve roots of the musculocutaneous nerve
c5, c6, c7
nerve roots of the axillary nerve
c5, c6
nerve roots of the median nerve
c5, c6, c7, c8, t1
nerve roots of the radial nerve
c5, c6. c7, c8, t1
nerve roots of the ulnar nerve
c8, t1, could also be c7
what nerve do the roots give off and where does this nerve innervate
the long thoracic nerve, innervates the serratus anterior
what are the spinal cord levels of the long thoracic nerve
c5, c6, c7
what nerve stems off of the cords of the brachial plexus and whats it innervate
the thoracodorsal nerve which innervates the latissmus dorsi
spinal cord level of the thoracodorsal nerve
c6, c7, c8
what cord does the axillary nerve come from
the posterior cord
what cord does the radial nerve come from
the posterior cord
what cord does the musculocutaneous nerve come from
the lateral cord
what cord does the median nerve come from
medial and lateral cords
what cord does the ulnar nerve come from
medial cord
