OF THE PELVIS, OR BASIN. 
_ This is situated in the lower region of the trunk. Its figure is — 
~ somewhat like a basin. It is composed of four bones, viz.two haunch _ 
bones, one sacrum or sacred bone, and the point bone at the lower 
end of the sacrum. Its use is to contain the organs of gener: 
_ the bladder, straight intestine, and support of the spine. 
These bones are situated at the sides of the basin. Their shape 
is irregular. Each bone is divided into three portions, viz. the 
haunch bone, the hip bone, and the share bone, or pubis. The emi- 
nences are, the crest of the uppermost part from which the trans- 
verse and slanting muscles of the abdomen arise ; at its back part 
are two spinous processes, which gives adhesion to ligaments ; at its — 
fore part are also two spinous processes ; the upper gives adhesion 
to the muscle, enabling persons to cross their legs, the stretcher of the 
sheath ofthe thigh, and the ligament of the thigh; the lower front 
spinous process, about an inch from the former, has, arising from | 
it, the straightener of the thigh. The outer surface of the haunch 
bone is covered with the buttock muscles; the internal by the in- 
ternal muscles. Upon the internal surface there is a line even with 
the pubis; this is the rim of the basin; it divides the cavity of the 
abdomen from the pelvis. Upon the lower portion of this bone are, 
x the bump upon which we sit ; the spinous process of the hip, which — 
» ‘projects backwards, and gives adhesion to the uppermost ligament, 
_ conn ting the haunch bone to the sacrum; and the branch of the 
ip, which joins the share bone. Upon the share bone are, the body, 
lear the socket, the angles and arches of the pubis. The cavities

in the bip ; the socket which receives the head of the thigh 
bone; andthe oval hole. Each haunch bone is connected with its 
_ fellow n ‘ront by ossification ; with the sacred bone by strong liga-_ 
Ae — cartilages ; and with the head of the thigh bone by ball
