Upper Limb
Name the two major superficial veins of the upper limb. - correct answer-The cephalic and
basilic vv
Both these superficial veins originate distally at what structure? - correct answer-They
originate at the dorsal venous network (arch) of the hand.
These superficial veins communicate again in the cubital fossa via what structure? - correct
answer-The median cubital v.
Name the muscles that arise from the vertebral column and connect the upper limb to the
trunk. - correct answer-The trapezius, levator scapulae, rhomboideus major and minor and
the latissimus dorsi.
Which of these muscles is not innervated by a branch off the brachial plexus? - correct
answer-The trapezius (CN XI - spinal accessory n.).
Name the muscles arising from the thoracic wall that connect the upper limb to the trunk. -
correct answer-The pectoralis major and minor, serratus anterior, subclavius, and the
sternocleidomastoid.
Which of these muscles is located deepest? - correct answer-The serratus anterior.
For what two nerves is the pectoralis minor a landmark? - correct answer-The medial and
lateral pectoral nn.
Why is the nomenclature of these nerves reversed with regard to the anatomical location? -
correct answer-Their nomenclature is NOT related to their relationship to the pectoralis
minor but rather to the cord from which they arise off the brachial plexus.
Name the muscles of the scapular region. - correct answer-The subscapularis,
supraspinatus, infraspinatus, teres minor and teres major.
Which of the muscles of the scapular region is not a rotator cuff muscle? - correct
answer-The teres major is not a rotator cuff muscle.
What is the function of the rotator cuff? - correct answer-They apply the head of the humerus
to the shallow glenoid cavity of the glenohumeral joint.
Which aspect of the shoulder joint is not reinforced by these muscles and what is the clinical
significance of this? - correct answer-The inferior aspect. Shoulder dislocation occurs
inferiorly and then pops up anteriorly.
What structures pass through the quadrangular space? - correct answer-The axillary nerve
and the posterior circumflex artery.
