Nerve Regulators: Two types of nerves help to control the action of the digestive system. Extrinsic (outside) nerves come to the digestive organs from the unconscious part of the brain or from the spinal cord. They release a chemical called acetylcholine and another called adrenaline
Shortly after gastrulation, the body and organs of the embryo begin to form. This process is called <u>embryogenesis.</u>
<u></u>
- The process by which an embryo transforms into a fetus is known as embryogenesis.
- The three germ layers that eventually give rise to the various organs in the animal body are formed as a result of gastrulation.
- Embryogenesis is the name of this process. As a result of differentiation, organs emerge from the germ layers.
- The process of creating and growing an embryo from a zygote (zygotic embryogenesis) or a somatic cell is known as embryogenesis (somatic embryogenesis).
- An incredibly well-organized series of cell division, expansion, and differentiation takes place during embryo development.
