BIO 201 Midterm: Exam 2 Review
Document Summary
One of the major differences among skeletal muscle fiber types is in their resistance to fatigue. 50% decrease in the lumen diameter of the left anterior descending coronary artery. The resistance in this artery would increase (due to this narrowing) approximately by a factor of: 16, consider again the patient in question 8, ( 50% decrease in the lumen diameter of the left anterior descending coronary artery). You might expect that this drug probably binds to: muscarinic ach receptors, arteriography of a patient"s left renal artery shows narrowing of the radius of the artery by 25% (i. e. , 75% of the original lumen diameter remains). Joe is suffering from a spasm in his left main coronary artery impairing blood flow to the heart. Chris has inadvertently taken a reasonably large dose of his roommate"s verapamide, a new slow calcium channel inhibitor. It impairs ca movement across ++ the plasma membrane in the heart and affects both heart rate and contractility.
