[citation needed] The brain is divided into two hemispheres, each consisting of four lobes – the frontal, temporal, parietal and occipital lobes.

Epidural Anesthesia
Epidural Anesthesia samer kareem 14,525 Views • 2 years ago

If you’re considering an epidural to help manage the pain of childbirth, you’re not alone. More than 60 percent of women delivering at hospitals elect for an epidural during labor. And with good reason: An epidural is considered one of the safest methods of pain control, with just one in 3,000 pregnancies experiencing serious complications. It’s also good for you, since you’ll remain awake and alert during the birth, as well as for your baby, since the drugs will barely reach your bloodstream (so they can’t get into hers).

Human ovulation captured on film

To record the sequence, Stephan Gordts and Ivo Brosens of the Leuven Institute for Fertility & Embryology in Belgium performed transvaginal laparoscopy, which involves making a small cut in the vaginal wall and observing the ovary with an endoscope.

"This allows us direct access to and observation of the tubo-ovarian structures without manipulation using forceps," says Gordts.

For the photos of ovulation, which only accidentally captured the critical moment, Jacques Donnez at the Catholic University of Louvain (UCL) in Brussels, Belgium, used gas to distend the organs for photography. However, Gordts and Brosens planned the procedure to coincide with ovulation and used saline solution to "float" the structures.
Perfect timing

Observation was timed for the day of the peak of the patient's luteal hormone cycle. Ovulation was predicted to occur on the evening of the day of the LH peak, and the endoscope introduced at 6 pm.

A small amount of saline was used to float the opening of the fallopian tube, its fimbriae (the "fingers" that sweep the egg into the tube) and the ovary itself. This gives a more natural appearance than gas, says Gordts.

In the video, the fimbriae can be seen sweeping in time with the patient's heartbeat. A mucus plug can be seen protruding from the ovary – this contains the egg.

"The ovum is not captured 'naked'," says Gordts. "There is no eruption like a volcano."

Gordts says that in clinical practice it is not easy to organise the observation of ovulation. "We were probably lucky to be successful at our first attempt," he says.

The development of the gastrointestinal tract
The development of the gastrointestinal tract samer kareem 2,526 Views • 2 years ago

The gastrointestinal tract (GIT) arises initially during the process of gastrulation from the endoderm of the trilaminar embryo (week 3) and extends from the buccopharyngeal membrane to the cloacal membrane. The tract and associated organs later have contributions from all the germ cell layers. During the 4th week three distinct regions (fore-, mid- and hind-gut) extend the length of the embryo and will contribute different components of the GIT. The large mid-gut is generated by lateral embryonic folding which "pinches off" a pocket of the yolk sac, the 2 compartments continue to communicate through the vitelline duct. The oral cavity (mouth) is formed following breakdown of the buccopharyngeal membrane (oropharyngeal or oral membrane) and contributed to mainly by the pharynx lying within the pharyngeal arches (More? Head Development). Loss of buccopharyngeal membrane opens the tract to amniotic fluid through the remainder of development, and during the fetal period is actively swallowed.

Retro-sigmoid craniotomy (often called "keyhole" craniotomy) is a minimally-invasive surgical procedure performed to remove brain tumors. This procedure allows for the removal of skull base tumors through a small incision behind the ear, providing access to the cerebellum and brainstem. Neurosurgeons may use this approach to reach certain tumors, such as meningiomas and acoustic neuromas (vestibular schwannomas).

Bacterial meningitis is very serious and can be deadly. Death can occur in as little as a few hours. While most people with meningitis recover, permanent disabilities such as brain damage, hearing loss, and learning disabilities can result from the infection. There are several types of bacteria that can cause meningitis. Some of the leading causes of bacterial meningitis in the United States include Streptococcus pneumoniae, group B Streptococcus, Neisseria meningitidis, Haemophilus influenzae, and Listeria monocytogenes.

Blood circulation

our uterus (or womb) is normally held in place inside your pelvis with various muscles, tissue, and ligaments. Because of pregnancy, childbirth or difficult labor and delivery, in some women these muscles weaken. Also, as a woman ages and with a natural loss of the hormone estrogen, her uterus can drop into the vaginal canal, causing the condition known as a prolapsed uterus.

Heartburn
Heartburn samer kareem 1,782 Views • 2 years ago

Heartburn is a burning pain in your chest, just behind your breastbone. The pain is often worse when lying down or bending over. Occasional heartburn is common and no cause for alarm. Most people can manage the discomfort of heartburn on their own with lifestyle changes and over-the-counter medications. Heartburn that is more frequent or interferes with your daily routine may be a symptom of a more serious condition that requires medical care

-The cremasteric reflex test is considered positive if there is elevation of the testis in response to stroking the upper inner thigh. This reaction is typically absent in testicular torsion and boys under the age of 6 months. Although not completely reliable in older boys and adults, an absent cremasteric reflex is highly suggestive of torsion. Patients with epididymitis usually have a normal cremasteric reflex, with pain and swelling isolated to
