Bones of the Upper Limb - Listed in Proximal to Distal Order
Bone Structure Description Notes
clavicle an "S" shaped it articulates medially with the
bone located manubrium of the sternum and laterally
between the with the acromion process of the scapula;
sternum and the it forms a strut that supports the upper
scapula limb; it is frequently fractured; it is the
first bone to begin ossification during
development
sternal the thickened it is triangular in cross-section; it
extremity proximal end of articulates with the clavicular notch of
the clavicle the sternum through a synovial joint with
two joint cavities separated by an
articular disk; the sternoclavicular joint
has the action of a ball and socket joint,
but not the physical shape of one
acromial the flattened it is marked on its inferior surface at the
extremity lateral end of the junction of the medial 2/3 and the lateral
clavicle 1/3 by a roughened area for attachment
of the coracoclavicular ligament; it
articulates with the coracoid process of
the scapula through a syndesmosis; it
articulates with the acromion process of
the scapula through a synovial joint; due
to the shape of the distal clavicle, the
acromion process passes inferior to the
clavicle in acromioclavicular dislocations
scapula the bone of the the scapula floats in a sea of muscles, so
shoulder it is difficult to fracture; it articulates
with only one bone - the clavicle at the
coracoclavicular and acromioclavicular
joints
superior the superior edge the superior border of the scapula is
border of the scapula marked by the scapular notch laterally
, medial border the border of the it is an important site of muscle
scapula that runs attachments for the intermediate layer of
from the back muscles
superior angle to
the inferior angle
superior angle the angle of the it is the attachment site for the levator
scapula formed scapulae m.
at the union of
the superior and
medial borders
lateral border the portion of the it is an important site of muscle
scapula that runs attachments for the teres major m., teres
inferomedially minor m. and the long head of the triceps
from the brachii m.; it has a groove for passage of
infraglenoid the circumflex scapular a.
tubercle to the
inferior angle
inferior angle the angle of the the inferior angle of the scapula often has
scapula formed a slip of origin of the latissimus dorsi
by the union of attached to it
the medial and
lateral borders
glenoid cavity the articular it articulates with the head of the
surface located humerus; it is deepened by a
at the junction of fibrocartilaginous rim called the glenoid
the superior and labrum
lateral borders of
the scapula
supraglenoid a projection of it is the attachment site for the tendon of
tubercle bone located the long head of the biceps brachii m.
superior to the
glenoid cavity
infraglenoid a projection of it is the attachment site of the tendon o of
tubercle bone located the long head of the triceps brachii m.
inferior to the
glenoid cavity
