shoulder and arm living Flashcards
(53 cards)
what is the position of the scapula
LIES ON POSTERIOR AND LATERAL ASPECT OF CHEST
OVERLYING 2ND TO 7TH RIBS
what does the clavical connect
upper limb to axial skeleton
what is the difference between the medial 2/3 and lateral 1/3 of clavical
medial is convex anteriorly
lateral is concave anteriorly
what is the texture of superior and inferior surface of clavical
superior smooth - muscle only attached at ends
inferior rough - because of muscle attachments
what is in the subclavian groove of the clavical
subclavius muscle
what are the articulations of the clavical
medial end - sternum adn 1st cc
lateral - acromion
what is on the medial, anterior and lateral side of the humerus
medial - articular surface or head
lateral - greater tuberosity
anterior - lesser tuberosity
descibe the role and position of the capitulum
lateral
articulats with the radius in elbow flexion
what is the role of the trochlear and position
medial
articuates iwth ulna
what nerves does the humerous make contact with and how can they be damaged
axillary nerve -winds around surgical neck of humerus - damaged by shoulder disslocation
radial - runs in radial (spiral) groove and can be damaged in humoral shaft fractures
ulnar - runs posterior to medial epicondyle and is superficial - damaged in fractures and dislocations of elbow joint
median nerve - runs anterior to distal humerus - damaged in supracondylar fractures of the humerus and dislocaton of elbow joint
what is the relation of the great vessels and nerves to the clavical as they pass from neck to upper limb
go behind the convex medial aspect of clavical
palpate the subc;lavian artery pulse
above and behind medial end of clavical
palpate trunks of brachial plexus
cord like structurs in supraclavicular fossa
may cause discomfort
palpate the corocoid process
below the lateral 1/3 of clavical
what are the vertebral levels related to the scapula
superior angle of scapula - t2
medial end of scap spine - t3
inferior angle of scap - t7
