Final answer:
The condition that shows the fetal head elongated in the transverse diameter and shortened in the anteroposterior diameter is known as brachycephaly.
Step-by-step explanation:
The condition that shows the fetal head elongated in the transverse diameter and shortened in the anteroposterior diameter is known as brachycephaly.
Brachycephaly is a type of craniosynostosis, a condition where the sutures in the skull fuse prematurely. In brachycephaly, the sagittal suture closes too early, causing the skull to become wider and shorter than normal.
Unlike dolichocephaly, which is characterized by a long and narrow head, brachycephaly is characterized by a short and wide head.
