pso·as mi·nor mus·cle

(sō'as mī'nŏr mŭs'ĕl)
An inconstant muscle, absent in about 40%; origin, bodies of twelfth thoracic and first lumbar vertebrae and disc between them; insertion, iliopubic eminence through iliopectineal arch (iliac fascia); action, assists in flexion of lumbar spine; nerve supply, lumbar plexus.
Synonym(s): musculus psoas minor, smaller psoas muscle.

QL resides in the area between psoas major and psoas minor muscles and the tendon of origin of transversus abdominis.
The origins are on the lumbar vertebrae (psoas major and psoas minor muscles) and the inner pelvis (iliacus muscle) and inserts into the lesser trochanter on the femur.

The psoas minor is a long, slender skeletal muscle which, when present, is located anterior to the psoas major muscle.
psoas minor and is present approximately in the middle of linea arcuata (Figure 2).
INTRODUCTION: Psoas minor is a slender muscle of posterior abdominal wall, having short fleshy belly and long tendon, lying anterior to Psoas major muscle.
OBSERVATIONS: In the present study, Psoas minor muscle was present in 40% (8/20 cases) cadavers studied: Bilateral in 35% (7/20 cases); & Unilateral in 5% (1/20 cases).
The psoas muscle is comprised of both the psoas major and minor, but as the psoas minor is often absent in individuals, (3) this paper will focus on the psoas major.
(40) The psoas major muscle is intimately linked with the iliacus, psoas minor (if present), adductor group, and quadriceps muscles (rectus femoris in particular as it also aids with hip flexion), thus evaluation of these muscles for strength, flexibility, and palpating for tonicity and tenderness is necessary to aid management decisions.
The psoas major, psoas minor and the iliacus muscles combine to become the iliopsoas.
En ambas especies, las arterias ovaricas presentaron un trayecto inicial recto, la arteria derecha cruzando la superficie ventral de la vena cava caudal y el musculo psoas menor (psoas minor) derecho.
The aorta was found along with the ventral surface of lumbar and sacral vertebrae, dorsally to the colon, following the caudal vena cava to the right, with the Psoas major, Psoas minor and Quadratus lumborum.
