ssapiila, and becoming gradually higher and broader, as itap-
proaches the anterior part of the scapula, where it terminates
in a bread and flat process, called the acromion. The ante-
rior edge of this projection of the spine is concave, and forms
a surface of articulation for the clavicle. The triangular
shape of this bone gives rise to the denomination of angles and
sides; and of the three of the latter, the posterior one, which
k turned towards the vertebra, is ttroiid the bask, Th§ eo»
racoid process, which stands out oppofiite to the acromion, and
fives attachment to the peetoralis minor, and coracO'brachia-
iis muscles. The borders of the bone are called costm, and
the corners angles. The circle below the articular cavity is
•ailed the neck.
Cavities. The articular, or glenoid cavity, which receives
Ihe head of the humerus. A supraspinal cavity, above the
spinous process in which the supraspinatus muscle is lodged.
The infra-spinal carity, situated below the spine, is larger
than the other, and gives origin to the infra-spinatiis muscle ;
* sc-riiliviar notch on the superior margin, near its fore part,
for the passage of tiie superior scapulary vessels and nerves.
Connexion. The scapula is united with the clavicle by ar»
throdia, wiih the ribs and os hyoides by muscle, and with the
humerus by arthrodia.
Joints. The shoulder-joint is one of considerable impor-
tance ; it is loose, moveable, and very free in its motions. It
is formed by the large round head of the humerus, and the
jhallow articular cavity of the scapula, the sides of which are
elevated with cartilage. A capsular ligament, large, wide,
and loose, fixed to the neck of the scapula and humerus, sur-
rounds this joint. A considerable quantity ef synovia is re-
quisite to lubricate it, and accordingly it is supplied by seve-
ral bursa3, mucosae opening into it, independent of the natural
ssapiila, and becoming gradually higher and broader, as itap-
proaches the anterior part of the scapula, where it terminates
