![]() Conditions with atrophy typically involve cell loss or damage.įor example, spinal muscular atrophy occurs when muscles shrink due to a lack of stimulation from nerve cells. This can lead to abnormal growth or tumors.Ītrophy, such as muscle atrophy, occurs when an organ or tissue becomes smaller after reaching a normal size. For example, it may cause cells to grow at an abnormally high rate. Ureteral hypoplasia, on the other hand, occurs when the tube is present but underdeveloped.ĭysplasia refers to abnormal cell development within tissues or organs. Aplasia means that there is no tissue or organ at all.įor example, ureteral aplasia is the lack of a ureter, which is the tube that carries urine from the kidneys to the bladder. People with hypoplasia will have a tissue or organ with too few cells. Hypoplasia describes a lack of cell growth, but aplasia is a complete lack of an organ or tissue. lack of muscle control or coordination, such as difficulty speaking, walking, or swallowingĭifference between hypoplasia, dysplasia, aplasia, and atrophy.involuntary movements, such as eye movements. ![]() It is also associated with several inherited metabolic disorders, such as Williams syndrome, and some of the neurodegenerative disorders that begin in early childhood, such as ataxia telangiectasia.Īccording to the National Institute of Neurological Disorders and Stroke, because the cerebellum plays an important role in motor coordination, the symptoms of disorders involving cerebellar hypoplasia can include: These symptoms vary greatly from those of cerebellar hypoplasia, which affects the cerebellum.Ĭerebellar hypoplasia is a feature of several congenital malformation syndromes, including Walker-Warburg syndrome, which is a form of muscular dystrophy. accumulation of bacteria and tooth decay.hypersensitivity of the teeth to heat or cold.yellow, brown, or white marks and stains on the teeth.The consequences of hypoplasia depend on what area of the body it affects.įor example, enamel hypoplasia causes symptoms that include: ![]() Hypoplasia typically causes problems with how a tissue or organ functions.
