	'''spinal cord''' - part of the brain like a long rope running down your back. The spinal cord does what the brain tells it and allows you to move your muscles. The spinal cord is also the way you can to feel things with your skin (touch, hot, cold). It acts like a telephone cable passing messages from the brain to the body and from the body to the brain. If the spinal cord is damaged you cannot move your body.		'''spinal cord''' - part of the brain like a long rope running down your back.

			'''trimester''' - dividing a time into three parts. Because humans take 9 months to develop each trimester (first, second, third) is 3 months.

	'''uterus'''- the space within the mother where the embryo grows. It also grows when the embryo does and has lots of blood to feed the embryo and strong muscles in its walls for birth.

	Another measure to guess fetal age of increase in size are the long bones (in the limbs) and head diameter. These are usually measured by special sound waves (ultrasound) through the wall of the mothers tummy.
