The fifth week of pregnancy is considered part of the embryonic stage of prenatal development.
During this stage, the embryo continues to grow in size, the placenta and the amniotic fluid begins to form, and the mother experiences several hormonal changes as a response to the embryo's implantation into the uterus of the mother.
The embryo's cells begin forming specialized functions in a process called differentiation. The baby's heart, spinal cord, and brain begin to develop, so as his/her blood cells, kidney cells, and nerve cells. His/her external physical features also begin to form.
The embryonic stage ends at the end of the 10th or the beginning of the 11th week of pregnancy, where the developing baby is now called a fetus.
Memory has the ability to encode, store and recall information. Memories give an organism the capability to learn and adapt from previous experiences as well as build relationships. The types of encoding used by individuals to input information into the nervous system include;
Visual encoding which entails the process of encoding images and visual sensory information. Elaborative is the process of actively relating new information to knowledge that is already in memory, and Acoustic encoding which is the encoding of auditory impulses.
