Treating Physician Law and Legal Definition. A treating physician is defined as âsomeone who provides you, or has provided you, with medical treatment or evaluation and who has, or has had, an ongoing treatment relationship with you.
In the first four weeks from conception, fetal growth of the ovum begins with development of the spinal cord, nervous system, gastrointestinal system, heart and lungs. By eight weeks, in the embryonic stage, the face is forming, arms and legs move, the baby's heart begins beating and the brain and other organs form.
The process of prenatal development occurs in three main stages. The first two weeks after conception are known as the germinal stage; the third through the eighth week are known as the embryonic period, and the time from the ninth week until birth is known as the fetal period.
