Flashcards in Anterior Shoulder Deck (23):
1

jugular notch structure

created by two jugular eins

2

xiphoid process

bottom of rib cage that juts out

3

midaxillary line

essentially midline coronally

4

cephalic vein

Run down upper extremity and start posteriorily through deltopectoral groove

5

basilic vein

run down upper extremity and start anteriorly

6

median cubital vein

connects cephalic and basilic veins

7

deltopectorial triangle 6

deltoid

pectorals major

clavicle

has branches of lateral pectoral nerve
and thoracoacromial artery

also starting point of cephalic vein though arm

8

Deltoid attachments

clavicular-start from lateral one third of clavicle

acromial-start from accordion

spinal part-originates from scapular spine

All end on deltoid tuberosity of humorous

9

deltoid innervation and verts

axillary nerve

c5-6

10

deltoid actions

clavicular-flex, internally rotatem and adduct arm at shoulder

acromial part-abduct arm

spinal-extend, externally rotate and adduct arm to shoulder

60-90 degrees of abduction-clavicular and spinal parts help with abduction

11

pec major attachments

clavicular part-from medial half of clavicle

sternocostal-from sternum and costal cartilages 1-6

abdominal part-anterior layer of rectus sheath-4th rib from bottom

all insert onto crest of greater tuberosity on humorous

12

pec major innervation and vert

medial and lateral pectroal nerves

c5-t1

13

pec major actions

all-adduct and interally rotate arm at shoulder

claviular and sternocolstal-flex arm at shoulder and assist in respiration when shoulder fixed

14

medial pectoral nerve

innervates pecs minor and major

15

lateral pectoral nerve

innervates pec major

16

throacoaromial artery

derived from axillary

17

pec minor attachments

originates from 3-5th ribs

inserts in coracoid process

18

pec minor innervation and verts

medial pectoral nerve

c8-t1

19

Pec minor actions

draws scapula downward
-causes inferior angle to move posteriomedially (kinda pops out inferior scapula backwards and medially)

rotate glenoid inferiorly and assist in respiration

20

axilarry artery branches

superior thoracic artery

thoracoacromial and lateral thoracic arteries

anterior/posterior cicumfle artires and subscapular artery

21

superior thoracic artery

-extends form lateral edge of first rib to medial boarder of muscle (i think pec minor)

22

thoracoacromial and lateral thoracic arteries

-lie under pec minor and start as one branch of axillary

23

anterior/posterior cicumfle artires and subscapular artery

-all start as one
-extends from lateral margin of muscle down to where artery crosses tendon of trees major
