Consistency in size and asymmetry of the psoas major muscle among elite footballers
British Journal of Sports Medicine, 2009 ObjectiveTo determine, using magnetic resonance imaging (MRI), the cross-sectional area (CSA) of the psoas major (PM) muscle across multiple vertebral levels, to examine any asymmetry of the PM muscle and investigate the consistency across vertebral levels, and to determine whether a relationship exists between low back pain (LBP) and the size or ...

The principal artery of the psoas major muscle
Surgical and Radiologic Anatomy, 1989The psoas major m. has a complex arterial supply, derived from the lumbar, iliolumbar, obturator, external iliac and common femoral a. The branches arising from the external iliac a., though quite often multiple and slender, are represented in 75% of cases by a single large-caliber vessel. This principal artery of the psoas m.

Lumbar Plexus and Psoas Major Muscle
Regional Anesthesia and Pain Medicine, 2008Background and Objectives: Conflicting definitions concerning the exact location of the lumbar plexus have been proposed. The present study was carried out to detect anatomical variants regarding the topographical relation between the lumbar plexus and the psoas major muscle as well as lumbar plexus anatomy at the ...

Direct Electromyography of the Psoas Major Muscle in Man
The Journal of Bone & Joint Surgery, 1966Electromyographic studies of the psoas major muscle were performed on five patients with wire electrodes implanted directly into the muscle during lumbar sympathectomy. Recordings made during various activities, approximately ten days after operation, indicated that this muscle has a regular and significant role in advancing the limb while walking and ...

Composition of the rat psoas major muscle
2015Introduction. Rat psoas major muscle arises from lumbar vertebrae and inserts at the lesser trochanter of the femur. Unlike humans, the rat is a quadruped, and only occasionally rises on its hind legs. Therefore, composition of the rat psoas major muscle is expected to differ in relation to humans. Material and methods.
