The psoas sign is a medical sign that indicates irritation to the iliopsoas group of hip flexors in the human abdomen abdomen , and consequently indicates that the inflamed appendix is retrocaecal in orientation as the iliopsoas muscle is retroperitoneal . It is elicited by performing the psoas test by passively extending the thigh of a patient lying on his side with knees extended, or asking the patient to actively flex his thigh at the hip. ref cite book last Bickley first Lynn S. title Bates Guide to Physical Exam and History Taking edition 9th publisher Lippincott, Williams, and Wilkins pages 390 ref If abdominal pain results, it is a positive psoas sign . The pain results because the psoas borders the peritoneal cavity , so stretching by hyperextension at the hip or contraction by flexion of the hip of the muscles causes friction against nearby inflamed tissues. In particular, the right iliopsoas muscle lies under the Vermiform appendix appendix when the patient is supine position supine , so a positive psoas sign on the right may suggest appendicitis .

Contraction of the supraspinatus muscle leads to Anatomical terms of location Relative motions abduction of the arm at the shoulder joint. It is the main agonist muscle for this movement during the first 10 15 degrees of its arc. Beyond 30 degrees the deltoid muscle becomes increasingly more effective at abducting the arm and becomes the main propagator of this action. The supraspinatus muscle is one ...

At just over one millimeter in length, its purpose is to stabilize the smallest bone in the body, the stapes . The stapedius emerges from a pinpoint foramen in the apex of the pyramidal eminence a hollow, cone shaped prominence in the posterior wall of the tympanic cavity , and inserts into the neck of the stapes. Function It reflexively dampens the vibrations of the stapes by pulling on the neck of that bone. It prevents excess movement by the stapes , helping to control the amplitude of sound sound waves from the general external environment to the inner ear . The stapedius muscle dampens the ability of the stapes vibration and protects the inner ear from high noise levels, primarily the volume of your own voice. Compare also the role of the tensor tympani muscle, which primarily dampens those sounds associated with chewing.
