The anterosuperior view of the head of an anencephalic fetus

Anencephaly is a severe congenital birth defect characterized by the absence of major portions of the brain, skull, and scalp. The image shows an anterosuperior view of an anencephalic fetus, demonstrating the distinctive facial features and cranial abnormalities that define this condition. This devastating neural tube defect occurs during early embryonic development when the neural tube fails to close properly at the cranial end, resulting in the absence of significant portions of the brain, particularly the cerebrum and cerebellum. Despite these profound structural abnormalities, the brainstem and spinal cord often remain intact, allowing for basic physiological functions in affected fetuses.

Understanding the Stages of Neural Tube Formation: A Detailed Guide

The process of neural tube formation is a critical step in embryonic development, laying the foundation for the central nervous system. This diagram illustrates the key stages—starting from the neural plate to the formation of the neural tube and neural crest—offering valuable insights for medical students and professionals studying developmental biology. Explore this comprehensive guide to understand the intricate process and its significance in human anatomy.
