                       1. Preganglionic neuron - from CNS (spinal cord or brain) to the autonomic ganglion, all of these fibers release acetylcholine (Ach)

                       2. Postganglionic neuron - from the autonomic ganglion to the cells of the effector organ, parasympathetic postganglionic fibers release acetylcholine while sympathetic postganglionic fibers release norepinephrine.

Your 1 st section should be about reproduction in humans.
jekas [21]

The human reproductive system is different in males and females. When a sperm and egg join, the egg is fertilised and a baby starts to develop. Its mother provides all a baby’s needs until it is born.Fertilisation happens when an egg cell meets with a sperm cell and joins with it. The fertilised egg divides to form a ball of cells called an embryo. The embryo attaches to the lining of the uterus. It begins to develop into a fetus and finally into a baby.The mother’s lifestyle can affect the developing fetus. For example, smoking reduces the amount of oxygen in the bloodstream. This can lead to low birth weight and premature birth (when a baby is born too soon). Drinking alcohol during pregnancy can harm the developing baby’s nervous system, especially its brain.

Birth

It takes about 40 weeks for a baby to develop in the uterus. This time is called gestation. After this, the baby is ready to be born. The cervix relaxes and muscles in the wall of the uterus contract. Waves of muscle contraction push the baby out of the mother's body through the vagina.
