Description

Pain in appendicitis Distention of the GI tract causes referred pain. The crampy epigastric pain felt at the beginning of appendicitis occurs because of visceral sensory axons from the appendix have cell bodies located in the T10 dorsal root ganglia. Therefore, the pain refers to the T10 dermatome (remember the mnemonic T10 controls the belly But-ten). Later in its course, the inflammation of the appendix irritates the local peritoneum, which is innervated by somatic pain fibers of T12. The McBurney point lies in the T12 dermatome. Cremasteric reflex The reflex is initiated by stimulating the Ilioinguinal and genitofemoral nerve. Ilioinguinal nerve is the afferent (sensory). Genital branch of the genitofemoral nerve is the efferent (motor) which supplies the Cremasteric muscle. The Cremasteric muscle is an extension of the internal abdominal oblique muscle. The Cremasteric reflex can also be lost with injury to the Ilioinguinal nerve in surgery and spinal cord injury....
