The psoas major (/ ˈsoʊ.əs / or / ˈsoʊ.æs /; from Ancient Greek: ψόᾱ, romanized: psóā, lit. 'muscles of the loins') is a long fusiform muscle located in the lateral lumbar region between the vertebral column and the brim of the lesser pelvis. It joins the iliacus muscle to form the iliopsoas. In animals, this muscle is equivalent to ...

[2] Symptoms commonly include right lower abdominal pain, nausea, vomiting, and decreased appetite. [2] However, approximately 40% of people do not have these typical symptoms.

Pott's disease, or Pott disease, named for British surgeon Percivall Pott who first described the symptoms in 1799, [1] is tuberculosis of the spine, [2][3] usually due to haematogenous spread from other sites, often the lungs. The lower thoracic and upper lumbar vertebrae areas of the spine are most often affected.
The psoas is an important ribbon-shaped muscle that runs from your lower lumbar spine (the lower back) to the top of the femur (thigh bone), explains Jim White, R.D.N., A.C.S.M. Ex-P , owner of ...
The psoas sign, also known as Cope's sign (or Cope's psoas test[1]) or Obraztsova's sign, [2] is a medical sign that indicates irritation to the iliopsoas group of hip flexors in the abdomen, and consequently indicates that the inflamed appendix is retrocaecal in orientation (as the iliopsoas muscle is retroperitoneal).
The psoas minor muscle originates from the vertical fascicles inserted on the last thoracic and first lumbar vertebrae. From there, it passes down onto the medial border of the psoas major, and is inserted to the innominate line and the iliopectineal eminence. Additionally, it attaches to and stretches the deep surface of the iliac fascia and ...
The iliopsoas muscle (/ ˌɪlioʊˈsoʊ.əs /; from Latin ile 'groin' and Ancient Greek ψόᾱ (psóā) 'muscles of the loins') refers to the joined psoas major and the iliacus muscles. The two muscles are separate in the abdomen, but usually merge in the thigh. They are usually given the common name iliopsoas. The iliopsoas muscle joins to ...
Infectious diseases, surgery, gastroenterology. Psoas abscess is a collection of pus (abscess) in the iliopsoas muscle compartment. [1][2] It can be classified into primary psoas abscess (caused by hematogenous or lymphatic spread of a pathogen) and secondary psoas abscess (resulting from contiguous spread from an adjacent infectious focus).
