What's the difference between muscle and psoas?

Muscle


Definition:

  • (n.) An organ which, by its contraction, produces motion.
  • (n.) The contractile tissue of which muscles are largely made up.
  • (n.) Muscular strength or development; as, to show one's muscle by lifting a heavy weight.
  • (n.) See Mussel.

Psoas


Definition:

  • (n.) An internal muscle arising from the lumbar vertebrae and inserted into the femur. In man there are usually two on each side, and the larger one, or great psoas, forms a part of the iliopsoas.

Example Sentences:

  • (1) Findings on plain X-ray of the abdomen, using the usual parameters of psoas and kidney shadows in the Nigerian, indicate that the two communities studied are similar but urinary calculi and urinary tract distortion are significantly more prominent in the community with the higher endemicity of urinary schistosomiasis.
  • (2) The inflammatory bowel disease (IBD) is sometimes complicated by the development of a psoas abscess.
  • (3) Although the condition is common in the tropics, an acute pyogenic psoas abscess should always be considered in the differential diagnosis of pain in the hip region.
