Question

the fetus is very active prior to the eighth week after fertilization.

true

false

Explanation:

Define the developmental stages

Using the Embryonic Stage and Fetal Stage Timeline knowledge points

• The embryonic stage lasts from fertilization until the end of the eighth week.
• The developing organism is called an embryo, not a fetus, during this period.
• The fetal stage begins at the ninth week after fertilization.

Analyze early movement and activity

Using the Fetal Muscle Development knowledge point

• Significant muscle development and coordinated movement occur during the fetal stage.
• Prior to the eighth week, the embryo's muscles and nervous system are just beginning to form.
• Active, coordinated movements do not occur prior to the eighth week.
• Therefore, the statement is false because the organism is not yet a fetus and is not highly active.

Answer:

• TRUE
• FALSE (Correct answer)
