Congenital Abnormalities and Dysmorphisms
Terms in this set (14)
"born with"; it does not imply or exclude a genetic basis for the birth defect!
deviation from normal
May not become clinically apparent until years later
an anatomical deviation, something just does NOT look right
primary errors of morphogenesis due to intrinsically abnormal developmental process; multifactorial
Ex. Cleft lip/palate
secondary destruction of a previously normally-developed organ or body region due to extrinsic disturbance
Ex. Amniotic band syndrome
extrinsic disturbance caused by abnormal biomechanical forces (i.e.compression)
a cascade of anomalies triggered by one initiating aberration
constellation of anomalies that cannot be explained on the basis of a single initiating defect...basically a group of signs and symptoms that occur together and characterize a particular disease/abnormality with the definitive cause being not known/understood.
complete absence of an organ and its associated primordium (no development)
absence of an organ, but rudiment/primoridum structure present (incomplete development)
abnormal development, maturation, and differentiation
underdevelopment or incomplete development or decreased size of a tissue or organ
absence of an opening, usually of a hollow visceral organ, such as trachea, esophagus, and intestine
a birth defect of the brain characterized by the premature closure of one or more of the fibrous joints between the bones of the skull (called the cranial sutures) before brain growth is complete.
