Leonardo mistakenly depicted the cotyledons in the vascular walls of the human uterus that he had previously found in a cow uterus. [3] The other study, measuring 30.3×22 cm, shows female external genitalia , the supposed arrangement of abdominal muscles on the top right and fetus from different angles.
A, early embryonic stage, showing the cloaca receiving the urinary bladder, the rectum, and the Wolffian duct, as in the lower vertebrates. B , later stage, showing the beginning of the fold which divides the cloaca into a ventral urogenital sinus which receives the urinary bladder , Wolffian ducts, and ureters , and into a dorsal part which ...
The uterus or womb is the major female reproductive organ. The uterus provides mechanical protection, nutritional support, and waste removal for the developing embryo (weeks 1 to 8) and fetus (from week 9 until the delivery). In addition, contractions in the muscular wall of the uterus are important in pushing out the fetus at the time of birth.
Obstetric ultrasonography, or prenatal ultrasound, is the use of medical ultrasonography in pregnancy, in which sound waves are used to create real-time visual images of the developing embryo or fetus in the uterus (womb).
The vasoconstriction of the effects of cocaine lead to a decrease in placental blood flow to the fetus that results in fetal hypoxia (oxygen deficiency) and decreased fetal nutrition; these vasoconstrictive effects on the placenta have been linked to the number of complications in malformations that are evident in the newborn.

The blue line is the mean and the green area delimits the 3rd versus the 97th percentile. [1] Ultrasound image of the foetus at 12 weeks of pregnancy in a sagittal scan. Measurements of fetal Crown Rump Length (CRL). The embryo and fetus float in the amniotic fluid inside the uterus of the mother usually in a curved posture resembling the ...
