Memory – Deep inside the medial temporal lobe is the region of the brain known as the limbic system, which includes the hippocampus, the amygdala, the cingulate gyrus, the thalamus, the hypothalamus, the epithalamus, the mammillary body and other organs, many of which are of particular relevance to the processing of memory.
Brain damage/brain injury is the destruction or degeneration of brain cells. Brain injuries occur due to a wide range of internal and external factors. In general, brain damage refers to significant, undiscriminating trauma-induced damage, while neurotoxicity typically refers to selective, chemically induced neuron damage. A common category with the greatest number of injuries is traumatic brain injury following physical trauma or head injury from an outside source, and the term acquired brain injury is used to differentiate brain injuries occurring after birth from injury, from a genetic disorder, or from a congenital disorder.
Menstrual pain/cramps happen because of contractions in the uterus, or womb, which is a muscle. If it contracts too strongly during your menstrual cycle, it can press against nearby blood vessels. This briefly cuts off the supply of oxygen to the uterus. It’s this lack of oxygen causes your pain and cramping. Many women have menstrual cramps just before and during their menstrual periods. For others, menstrual cramps can be severe enough to interfere with everyday activities for a few days every month. Conditions such as endometriosis or uterine fibroids can cause menstrual cramps. Treating the cause is key to reducing the pain. Menstrual cramps that aren’t caused by another condition tend to lessen with age and often improve after giving birth.
