Upper Extremitie Arteries And Nerves Flashcards
Median Nerve
Runs down middle of the forearm
Ulnar nerve
Runs down ulna bone on pinky side of arm
Brachial artery
Runs down middle of bicep
Ulnar artery
Artery that breaks off from brachial artery and runs down ulna side of arm
Radial artery
Runs down radial side of arm thumb side and breaks off from brachial artery
2 different branches of radial nerve on thumb side of arm
Deep and superficial
Nerves associated with upper extremity
Brachial plexus and major branches

5
Two points of attachment for spinal nerves?
Posterior and anterior root
Spinal nerves posterior roots have?
Sensory fibers
Anterior roots in spinal nerves have
Motor fibers
Spinal nerves unite at
Intervertebral foremen
When spinal nerves branches they are known as
RAMI (ventral and dorsal)
Plexus: Braid
Forms networks of nerves by branching and joining other nerves
Brachial plexus is
Entire nerve supply of ue and shoulder region
Brachial plexus is made up of ventral nerve roots of
Cervical vertebrae 5 through thoracic vertebra 1
What is found in the axilla (axillary) region?
Numerous nerves and blood vessels
3 brachial plexus major branches
Superior trunk
Middle trunk
Inferior trunk
Superior trunk is located
C5-6
Middle trunk is located?
C7
Inferior trunk is located
C8-t1
Each trunk of the brachial plexus divides
Anterior and posterior division
Divisions unite to form 3 cords?
Lateral medial and posterior
Axillary nerve
Supplies deltoid and teres minor
Musclocutaneous nerve
Flexors is muscles in arm and forearm
Radial nerve
Controls muscles on posterior aspect of arm
Ulnar nerve controls
Anteromedial muscles of arm and most palm muscles
Median nerve controls
Most muscles of arm and some palm
