[Properly pl. of psoa, a. Gr. ψόα, usually in pl. ψόαι, acc. ψόας, the muscles of the loins. From the rare occurrence of the sing., the pl. psoas has been erroneously taken as sing.]
The name of two muscles of the hip: (a) psoas magnus, a large flexor muscle of the hip-joint which arises from the lumbar vertebræ and sacrum and is inserted along with the iliac into the lesser trochanter of the femur; cf. iliopsoas; (b) psoas parvus or psoas minor, a muscle (inconstant in man) which in many mammals forms a powerful flexor of the pelvis upon the spine.
