PART 1: Explain the effects of hyperkalemia on the heart. Be sure to note whether hyperkalemia causes depolarization or hyperpolarization of the heart cells. Be sure that you explain how this affects the contraction (EKG readout) of the heart.

PART 2: Explain at least two fundamental differences between SKELETAL muscle tissue and CARDIAC muscle tissue. You may choose to comment on their Anatomical differences or physiological differences.

PART 3: Explain how angina pectoris (“choked chest”) is different from a myocardial infarction (MI, also known as a “heart attack”)
