Muscles and Ligaments

– Discussion:     – T1 images provide contrast between muscles & adjacent tissues;     – normal Muscle has low-intermediate signal intensity on both T1 & T2 images where as inflammation and lesions of muscle will have an increased signal on T1 & (even higher on) T2 images,     – its important to note … Read more

Muscle Contraction

– Isometric Contraction:     – w/ isometric (static) contraction, external muscle length does not change;     – internally, however, within the fibril the distance between the Z-lines does shortens; – Isotonic Contraction:     – is one in which constant internal force is produced, & muscle shortens;     – it is  also defined … Read more
