Slide 362A Atrophy of skeletal muscle. This type of atrophy follows interruption of the nerve supply to a muscle or part of a muscle. There are two possible causes for the atrophy 1) disuse 2) loss of nerve supply. The presence of cross striations indicate that this is striated muscle and the peripheral location of the nuclei distinguishes it from cardiac muscle.
Slide 55B Coronary artery with atherosclerosis. The wall of the artery shows atheromas and numerous cholesterol crystals.
