lateral (axillary) border
thickest part of bone
head of scapula (glenoid cavity)
neck of scapula inferior to head
Midline marker for superior level of liver, central tendon of diaphram
inferior border border of heart
cartilaginous in young people. Bone after 40.
false (vertebrochondral) ribs
8-10 cartilage joined to cartilage of rib just superior to them. Indirect connection to sternum
11 & 12. have rudimentary cartilages. not connected, end in posterior abdominal musculature
connects upper limb to trunk
sternal end connects with manubrium of sternum.
acromial end joins acromion of scapula.
Medial two thirds of shaft curve anteriorly
lateral third flat and concave anteriorly
each side of jugular notch on manubrium.
articulates with sternal (medial) end of clavicle
sternal angle of Louis
(T4-T5, level of 4th disc) opposite second pair of costal cartilages. Clinical landmark (between manubrium & body)
wedge-shaped & 2 facets, separted by crest of head.
1 facet for vertebra superior to it
1 facet for connecting numerically corresponding vertebra
junction of neck and body.
(smooth articular part) for connecting corresponding transvers process of vertebra
(rough nonarticular part) for attachment of costatransverse ligament
broadest (body widest, nearly horizontal)
shortest, most sharply curved.
2 grooves crossing superior surface for subclavian vessels, separated by scalene tubercle and ridge.
one facet on head
separate ribs and cartilages from one another. spaces and neurovascular structures are named according to rib forming superior border of space. 11 spaces and nerves.
posterior surface of scapula
unevenly divided by spine of scapula
into small supraspinous fossa
larger infraspinous fossa
Scapula borders are
superior, inferior angles
serves as strut (rigid support)
keeps limb away from thorax
enables elevation of ribs for deep inspiration
forms a boundary of cervicoaxillary canal for protection of neurovascular bundle supplying upper limb
transmits shocks from upper limb to axial skeleton
No bone marrow, has spongy bone with shell of compact bone. But considered long bone
