Menstruation Symptoms

It is common for women of child-bearing age to experience a variety of different symptoms before, during, or after their menstruation.

The term menstrual cycle is used to describe the hormonal and reproductive tissue changes that occur in adult females during their reproductive years. It does not represent an independent physiological process, since it is unlikely that there was a selection independent of the evolutionary events that led to it.

What is Menstruation?

The major function of the female genital tract is to produce mature and fertilizable ova. In contrast to other tissues of the body, ovaries and other parts of this system undergo repetitive cyclical changes in response to estrogen and progesterone stimulation. Such changes that occur at approximately monthly intervals are most prominent in the endometrium, and the shedding of uterine lining is called menstruation.

After an Ectopic Pregnancy

An ectopic pregnancy occurs when a fertilized ovum implants in an area outside of the womb, usually in one of the fallopian tubes. Since this space is not suitable for the baby to develop, the fertilized egg does not usually develop into a baby. If growth of an ectopic pregnancy is not prevented, the fallopian tube can rupture and cause dangerous internal bleeding that is life threatening to the mother.

What Causes an Ectopic Pregnancy?

Every month, females of reproductive age release an egg or ovum from one of their ovaries during the menstrual cycle. This egg travels from the ovary towards the womb via the fallopian tube, where it may or may not be fertilized by sperm.

Types of Ectopic Pregnancy

An ectopic pregnancy is classified according to where exactly the fertilized egg implants. Some examples of the different types of ectopic pregnancy are described below.

What is an Ectopic Pregnancy?

When the fertilized ovum is implanted at any location other than the uterine endometrium, it is called an ectopic pregnancy.

Hippocampus Evolution

The hippocampus has a long evolutionary history. Some features have been conserved, like connection to other brain areas, and some have diverged.

Hippocampus Physiology

The hippocampus functions in two different modes, each of which have their own specific pattern of neural and electrical activity that can be measured using an electroencephalogram (EEG). These two modes are called the theta mode and the large irregular activity (LIA) mode. The characteristics of each in the case of a rat's brain, are given below.

Hippocampus Functions

The hippocampus is a small organ located within the brain's medial temporal lobe and forms an important part of the limbic system, the region that regulates emotions. The hippocampus is associated mainly with memory, in particular long-term memory. The organ also plays an important role in spatial navigation.

Listeria Treatments

Listeria is a genus of small, motile gram-positive bacilli that infect many types of animals and contaminates numerous foods.

Listeria Pathogenesis

Listeria monocytogenes represents a universal, fast-growing, gram-positive bacterium with a diverse ecological niche and host range. Infection of humans and animals with this microorganism is traced to contaminated foods and can lead to serious (often lethal) disease known as listeriosis. There are also other species of the Listeria genus; however, their link to human disease is tenuous.

What is Listeria?

Listeria is a bacterial genus responsible for listeriosis, a significant foodborne disease that can be difficult to control.

LASIK Complications

LASIK is a safe and effective treatment for refractive errors, the most common of which include myopia, hyperopia, and astigmatism.

LASIK Safety

LASIK (laser in situ keratomileusis) is a surgery that uses a laser to reshape the cornea of the eye.

Visual Abberations After Laser Eye Surgery (LASIK)

Laser in situ keratomileusis (LASIK), or laser eye surgery, is a surgical technique for correcting refractive errors in vision but can cause visual aberrations.

LASIK History

Laser in situ keratomileusis (LASIK) is a popular surgery for refractive vision correction where cornea of the eye is reshaped by a laser. A convergence of numerous brilliant ideas and bioengineering accomplishments gave birth to this method, which undoubtedly represents one of the most efficient procedures in the history of medicine. Therefore LASIK is a common form of corrective surgery today and thousands of patients have benefited from the procedure.
