Fertilization and Implantation in human
Fertilization and Implantation in human samer kareem 3,162 Views • 3 years ago

Millions of sperms are deposited into the vagina during sexual intercourse. The sperms make their way through the cervix into the uterus and then on to the fallopian tubes. As they swim along this way their numbers decline. Only a few hundred sperm will get close to the egg. During the trip, sperm prepare themselves to meet the egg by subtle alterations of their heads and movement patterns. Once inside the fallopian tube, the sperm attracts the egg by releasing a chemical. The egg is surrounded by a protective covering called the zona pellucida, which allows only one sperm to penetrate it. Once inside the egg, the head of the fertilizing sperm releases its genetic contents, which fuses with the nucleus of the egg. Fertilisation is now complete. Sperm are able to survive for 2-3 days within the female's reproductive tract. The length of the time that a woman's egg can be fertilized by a man's sperm ranges from 12-24 hours.

How do you assess cerebellar function? Ask them to do this as fast as possible while you slowly move your finger. Repeat the test with the other hand. Perform the heel-to-shin test. Have the patient lying down for this and get them to run the heel of one foot down the shin of the other leg, and then to bring the heel back up to the knee and start again.

Closure of post infarction ventricular septal rupture samer kareem 12,779 Views • 3 years ago

Ventricular septal rupture (VSR) is a rare but lethal complication of myocardial infarction (MI). The event occurs 2-8 days after an infarction and often precipitates cardiogenic shock. [1] The differential diagnosis of postinfarction cardiogenic shock should exclude free ventricular wall rupture and rupture of the papillary muscles. (See the image below.)

Gastroschisis??
Gastroschisis?? samer kareem 7,628 Views • 3 years ago

Gastroschisis is a birth defect of the abdominal (belly) wall. The baby’s intestines stick outside of the baby’s body, through a hole beside the belly button. The hole can be small or large and sometimes other organs, such as the stomach and liver, can also stick outside of the baby’s body. Gastroschisis occurs early during pregnancy when the muscles that make up the baby’s abdominal wall do not form correctly. A hole occurs which allows the intestines and other organs to extend outside of the body, usually to the right side of belly button. Because the intestines are not covered in a protective sac and are exposed to the amniotic fluid, the bowel can become irritated, causing it to shorten, twist, or swell.

Management of COPD
Management of COPD samer kareem 2,027 Views • 3 years ago

The goal of COPD management is to improve a patient’s functional status and quality of life by preserving optimal lung function, improving symptoms, and preventing the recurrence of exacerbations. Currently, no treatments aside from lung transplantation have been shown to significantly improve lung function or decrease mortality; however, oxygen therapy (when appropriate) and smoking cessation may reduce mortality. Once the diagnosis of COPD is established, it is important to educate the patient about the disease and to encourage his or her active participation in therapy.

If you have been diagnosed with a bulging disc, you are not alone. Bulging discs, also known as a disc protrusion, are a very common occurrence. They usually remain asymptomatic; however, they can cause discomfort and disability in various parts of the body if the disc compresses an adjacent nerve root or the spinal cord. As we age, the outer fibrous portion of our discs can weaken. Pressure from the central core of the disc can then stretch to the outer rim, causing the disc to bulge. If left untreated, the disc can continue to bulge until it tears, which is classified as a herniated disc.
