Question

The ultrasound report tells Shaniqua and Charles that their developing infant is about one inch long and has eyes, a nose, lips, little arms and legs, and a beating heart. Given this information, the current period of prenatal development is the _____ period.

Answer 1

Embryonic period is the current period of prenatal development of the developing infant as reported in the ultrasound report given to Shaniqua and Charles.

Explanation:

The period after germinal implantation is the embryonic stage and lasts for about 56 days before the fetal stage

The embryonic period is marked by processes like rapid cell division, movement and cell differentiation through Carnegie stages or the developmental stages of the embryo.  

The embryonic cells develop into primary organs like the eyes, nose, lips, heart, brain, tiny limbs etc. of the fetus.

An ultrasound is usually taken during the embryonic period to study about the development of embryo and any congenital defects or malformations in the embryo. All the organ systems formed and functions like beating of the heart can be visualized through this ultrasound.
