Formation of the Notochord Quiz

Mesothelial cells differentiate into acidophilic organs known as the primitive cortex during the fifth week of development.

The fetal cortex regresses rapidly after birth, leaving only the inner layer known as the reticular zone.

Chromaffin cells in the adrenal glands originate from neural crest cells of the parasympathetic system.

During embryonic life, chromaffin cells are mainly located in the cortex of the adrenal glands.

Microcephaly results from a defect in the development of the cranial vault, leading to a smaller-than-normal head size.

Toxoplasmosis is a potential cause of microcephaly.

Cyclopia is a type of holoprosencephaly that occurs due to the incomplete cleavage of the prosencephalon into hemispheres.

Cyclopia typically occurs between the 28th and 38th day of gestation.

The definitive cortex forms after the original acidophilic cell mass surrounds the underlying mesenchyme.

The medulla of the adrenal glands is primarily composed of chromaffin cells.
