Micromyelia is a medical term that refers to a condition of underdevelopment of the spinal cord. The correct spelling of this word is [maɪkroʊmaɪ'liə], according to the International Phonetic Alphabet (IPA). The first syllable, "micro", is pronounced as [maɪkroʊ], while the second syllable, "myelia", is pronounced as [maɪ'liə]. The letter "c" is replaced by the letter "k" to represent the "k" sound in the word, making the spelling more phonetically accurate. Proper spelling of medical terms like micromyelia ensures accurate communication between healthcare professionals and accurate documentation of patient records.
Micromyelia is a medical term that refers to a rare congenital anomaly of the spinal cord characterized by an abnormally small or underdeveloped spinal cord. It is derived from the combination of the prefix "micro-" meaning small or tiny, and "myelia" which refers to the spinal cord.
Micromyelia is typically present from birth and is thought to occur due to abnormal development of the neural tube during fetal development. This condition is considered a form of spinal dysraphism, a group of disorders characterized by defects in the formation of the spinal cord and its surrounding structures.
The exact cause of micromyelia remains unclear, but it is believed to result from a combination of genetic and environmental factors. Some studies suggest that certain genes may play a role in the development of micromyelia, while others propose that exposure to certain teratogenic substances during pregnancy could contribute to this condition.
Individuals with micromyelia may present with a range of symptoms, which can vary depending on the extent and location of the underdevelopment. Common signs and symptoms include motor dysfunction, sensory deficits, muscle weakness or paralysis, spinal deformities, and urinary or bowel incontinence. The severity of these symptoms can also vary greatly, ranging from mild to severe, and may affect different parts of the body depending on the specific area of the spinal cord affected.
Micromyelia is typically diagnosed through medical imaging, such as magnetic resonance imaging (MRI) or computed tomography (CT) scans, which help visualize the size and structure of the spinal cord. Treatment options for micromyelia are often focused on managing the symptoms and providing supportive care, although surgical interventions may be considered in some cases.
Abnormal smallness or shortness of the spinal cord.

The word micromyelia is derived from two Greek roots: micros, meaning small, and myelos, meaning spinal cord. The suffix -ia is added to indicate a condition or disorder. Therefore, the term micromyelia literally translates to small spinal cord.
