OVULATION is a process whereby a secondary oocyte is related from the ovary following rupture of a mature Graafian follicle and becomes available for conception.

Only one secondary oocyte is likely to rupture in each ovarian cycle which starts at puberty and ends in menopause.
In relation to the menstrual period, the event occurs about 14 days prior to the expected period.
However, menstruation can occur without ovulation and ovulation remains suspended during pregnancy and lactation.



MECHANISM: The process of ovulation is a complex one. Pre-ovulation change occur both in the follicle and the oocyte.



EFFECT OF OVULATION:

THE ovum is picked up into the fallopian tube and undergoes either degeneration or further maturation. if fertilization is to occur.

Cystic Fibrosis- causes and symptoms

Image
Introduction Cystic fibrosis (CF) is a hereditary disorder that primarily affects the lungs and digestive system. It is characterized by the production of abnormally thick and sticky mucus that can clog the airways and obstruct the pancreas. CF is a progressive disease, leading to severe respiratory and digestive problems, and it often results in a shortened lifespan. Causes Cystic fibrosis is caused by mutations in the CFTR (cystic fibrosis transmembrane conductance regulator) gene. This gene is responsible for the production of a protein that regulates the movement of salt and water in and out of cells. Mutations in the CFTR gene result in the production of a defective protein, leading to the accumulation of thick mucus in various organs. Symptoms The symptoms of cystic fibrosis can vary widely but commonly include: Respiratory symptoms: Persistent coughing, frequent lung infections (including pneumonia and bronchitis), wheezing, and shortness of breath. Digestive symptoms: Difficu
