Pregnancy is a period of remarkable physiological adaptation, none more evident than the dramatic growth of the uterus. This muscular organ, which is normally the size of a pear, expands exponentially to accommodate the developing fetus, placenta, and amniotic fluid. The provided diagram vividly illustrates the progressive increase in uterine size throughout the three trimesters of pregnancy, offering a clear visual representation of this incredible transformation within the female body. Understanding this growth pattern is fundamental to monitoring fetal development and maternal well-being.

This striking image presents a human embryo at the crucial 7-week mark of development, measuring approximately 10 mm in length. Despite its diminutive size, this stage is characterized by rapid and significant organogenesis, with many foundational structures becoming discernible. The image provides a detailed view of the developing eyes, distinct limb buds, and the prominent tail, illustrating the incredible pace of morphological change during this early gestational period. This particular embryo was derived from an ectopic pregnancy, offering a rare and valuable photographic record of an early developmental stage.

Ultrasound imaging offers a critical tool for detecting fetal myelomeningocele, a neural tube defect visible at 21 weeks of gestation as shown in the provided image. This article explores the significance of this diagnostic image, providing a detailed look at the condition and its implications for prenatal care. Understanding these ultrasound findings can enhance awareness and guide effective medical management.

The CRIB II (Clinical Risk Index for Babies II) score is a validated risk-adjustment tool designed for use in neonatal intensive care units (NICUs) to predict mortality risk in preterm or very low birth weight (VLBW) newborns, specifically those born at <32 weeks gestation or weighing ≤1500 grams. It provides a standardized, objective method to assess illness severity and mortality risk within the first hour of NICU admission, aiding clinicians in risk stratification, quality assessment, and research.
