The illustration depicts a classic presentation of lumbar myelomeningocele, showing the external sac containing cerebrospinal fluid (CSF) protruding posteriorly from the lumbar region of the spine.

Anencephaly is one of the most severe neural tube defects compatible with life until birth, characterized by the absence of a major portion of the brain, skull, and scalp. The image depicts an anencephalic newborn in profile view, illustrating the distinctive craniofacial features associated with this condition. Anencephaly results from failure of the rostral (head) end of the neural tube to close during embryonic development, typically between the 23rd and 26th day of gestation. This devastating congenital anomaly is universally fatal, with most affected newborns surviving only hours to days after birth. Understanding the characteristic physical manifestations, underlying pathophysiology, and available management options is essential for healthcare professionals involved in perinatal and neonatal care.

Sexual organ development represents one of the most intricate and fascinating processes in human embryology. From the earliest stages of fetal development to the fully formed reproductive anatomy, this journey involves complex genetic, hormonal, and physiological mechanisms that shape human reproductive capabilities.

The development of the vertebral column represents one of the most intricate processes in human embryology. Through a series of precisely coordinated events, primitive tissue structures transform into the complex vertebral architecture that characterizes the mature spine. Understanding these developmental stages is crucial for medical professionals, particularly in addressing congenital spinal conditions and developmental abnormalities.
