Week Seven: Arms and legs begin to grow

  
You are 7 weeks pregnant. (five weeks from conception)
  • The embryo is around 13 mm (1/2 inch) in length.
  • The heart is beating with one chamber.
  • A dividing wall is formed in the heart.
  • Arm and leg buds begin to grow.
  • The lower jaw and the vocal cords are beginning to form.
  • The mouth opening is formed.
  • The inner ear is being created.
  • The digestive tract is developing
  • The navel string is being created
  • The following organs are being formed: the lungs, the liver, the pancreas and the thyroid gland.
The baby's eyes and inner ears are starting to develop. It is about now that your baby's major organs (heart, lungs liver, spleen, and kidneys) are beginning to develop. Your baby's digestive system is becoming more refined as the stomach and intestines develop. Remember the Folic Acid you should be taking? Well, since the Neural tube (later known as spinal cord) begins to fuse, folic acid is important in preventing neural tube defects. The embryo size is about a 1/8 inch (4mm) long.

embryo 5 weeksOn the 26th day after fertilization, the embryo's tiny heart begins to beat. Other major organs, including the kidneys and liver, have begun to develop, and the neural tube, which connects the brain and spinal cord, closes. The physical sensations of pregnancy have started--nausea, fatigue, sore breasts and frequent urination.

The embryo's arms and legs begin to grow from buds at each side. At first the hands and feet are shaped like paddles, but the fingers soon take shape. Lenses of the eyes appear - You would notice your baby's appearance is becoming increasing like a newborn's. Brain is growing well - Did you know that over the course of the remaining months that your baby's brain will develop over 100 billion neurons? This is just the beginning.
