Lack part of the ilium to the side of the sacrum and tranr^
verse processes of the lumbar vertebra'. It goes upwards to
be inserted into the points of the transverse processes and
the lower edge of the last rib. It supports the- loins, and
draws the spine to one side.
Psoas parvus. — Prelumbo-pubialis. — A muscle of the
loins, whicn arises from the last dorsal and first lumbar ver.
tebra?, and passes down by the side of the psoas magnus to
be inserted into the brim of the peivis, near the acetabulum.
It is often wanting. It bends the loins forwards.
Psoas magnus.—Prelumbo-trochuntineus.—A very long
and fleshy muscle filling the space upon the sides of the spine.
It arises by an upper head from the last vertebra of the back,
then successively from each lumbar vertebra, not only from
the sides of their bodies, but likewise from their transverse
processes. The muscle then descends thick, round, and
fleshy, to be united with the internal iliac muscle, under
Poupart's ligament, and the common tendon then bends ob-
liquely round to be inserted into the lesser trochanter. The
psoas muscles are in constant use in moving the thigh for-
Avards, and supporting the pelvis upon the thigh-bone.
Inflammation of the cellular membrane near this muscle
very frequently terminates in abscess, called psoas
abscess. Dissections prove that it more commonly
happens in the cellular structure around the muscle,
than in the muscle. After a short time, the pus de-
scends under Poupart's ligament, following the course
of this muscle in the cellular substance surrounding the
tendon and femoral vessels. At other times it insinu-
ates itself under the fascia of the thigh, and opens in
various places very remote from the psoas muscle;
nor is its appearance upon the loins and about the hip-
joint unfrequent. It mostly proves fatal.
