Pectoral girdle
(Figures 7.25, 7.26)
 
 
Clavicle is in superoanterior
thorax; articulates medially
with sternum and laterally
with scapula
Acromial end; sternal end
 
 
 
Scapula is in posterior thorax;
forms part of the shoulder;
articulates with humerus and
clavicle
Glenoid cavity; spine;
acromion; coracoid
process; infraspinous,
supraspinous, and
subscapular fossae
Upper limb
Arm (Figure 7.27)
 
 
Humerus is sole bone of arm;
between scapula and elbow
Head; greater and lesser
tubercles; intertubercular
sulcus; radial groove;
deltoid tuberosity;
trochlea; capitulum;
coronoid and olecranon
fossae; epicondyles; radial
fossa
Forearm (Figure 7.28)
 
 
Ulna is the medial bone of
forearm between elbow
and wrist; with the humerus
forms elbow joint
Coronoid process;
olecranon; radial notch;
trochlear notch; ulnar
styloid process; head
Hand (Figure 7.29)
 
 
Radius is the lateral bone
of forearm; articulates with
carpals to form part of the
wrist joint
Head; radial tuberosity;
radial styloid process;
ulnar notch
 
 
 
Carpals form a bony crescent
at the wrist; arranged in two
rows of four bones each
 
 
 
 
Metacarpals form the palm;
one in line with each digit
 
 
 
 
Phalanges form the fingers;
three in digits 2–5; two in
digit 1 (the thumb)
 
*The number in parentheses ( ) following the bone name denotes the total number of such bones in the body.
