Almost all the cells in your body were produced by mitosis. The only exception is sperm or eggs which are produced by a different type of cell division called meiosis.

Getting the right diagnosis often isn’t easy for psychiatric conditions. In our field, we don’t yet have biologic tests that can easily define one condition from another. If your blood pressure is 140 over 90, you have hypertension or high blood pressure. In mental health, we have to rely on a description of patterns or symptoms to makes diagnoses.

Medical providers divide the spinal cord into four distinct regions. Knowing the region in which the injury is located is often the key to understanding diagnosis and treatment. The four spinal cord regions are: The cervical spinal cord: This is the topmost portion of the spinal cord, where the brain connects to the spinal cord, and the neck connects to the back. This region consists of eight vertebrae, commonly referred to as C1-C8. All spinal cord numbers are descending, so C1 is the highest vertebra, while C8 is the lowest in this region. The thoracic spinal cord: This section forms the middle of the spinal cord, containing twelve vertebrae numbered T1-T12. The lumbar spinal cord: This is a lower region of the spinal cord, where your spinal cord begins to bend. If you put your hand in your lower back, where your back bends inward, you're feeling your lumbar region. There are five lumbar vertebrae, numbered L1-L5.
Is it possible to prevent cytomegalovirus infection? Is there a CMV vaccine? Cytomegalovirus (CMV) infection facts CMV is a common virus in the same family as herpesvirus, and it can infect anyone. CMV is spread by direct contact of body fluids, such as saliva, blood, urine, semen, vaginal fluids, and breast milk. Thus breastfeeding, blood transfusions, organ transplants, and sexual contact are possible modes of transmission. Most healthy people do not experience any symptoms when infected with CMV, and it does not pose a serious health concern. A majority of adults have antibodies consistent with past infection. Most healthy children and adults who do have symptoms will recover from CMV infection without complications and do not require antiviral treatment.
Most people develop several moles (nevi) throughout adulthood. Moles can be found anywhere on the body, usually in sun-exposed areas, and are usually brown, smooth, and slightly raised. In most cases, a nevus is benign and doesn't require treatment. Rarely, they turn into melanoma or other skin cancers. A nevus that changes shape, grows bigger, or darkens should be evaluated for removal.
