Notice the time line at the periphery. Preantral period: It takes 300 days for a recruited primordial to grow and develop to the class 2/3 (0.4 mm) or cavitation (early antrum) stage. Atresia can occur in preantral class 1, 2, and 3 follicles.
Best Answer: Hypercholesterolemia (literally: high blood cholesterol) is the presence of high levels of cholesterol in the blood. Hyperlipidemia is an elevation of lipids (fats) in the bloodstream. These lipids include cholesterol, cholesterol esters (compounds), phospholipids and triglycerides. Hyperlipidemia is caused by an elevated level of any kind of lipid (fat) in the blood stream, while hypercholesterolemia is only caused by high cholesterol in the blood stream.

Dear Jonathan, thank you for your question. Hypercholesterolemia and hyperlipidemia are indeed interchangeable terms that describe the same condition. Normal values for the cholesterol levels are as follows: - Total cholesterol 45 - LDL cholesterol < 130 - Triglycerides < 200 Currently, it is generally accepted that everyone over 30 years old have a complete lipid profile every 5 yrs.
