The [[Developmental Biology - Neurogenesis - Anatomy & Physiology|nervous system]] develops from ectoderm in the anterior part of the embryo, beginning with the formation of the neural plate. Some of the ectoderm will also develop into the epidermis in response to signalling factors from elsewhere in the embryo; formation of the neural ectoderm is the default pathway. The neural plate develops into the [[CNS Development - Anatomy & Physiology|neural tube]], which is the precursor to the brain and spinal cord.

In the verterbrate embryo, the anterior of the embryo also begins to form into blocks of cells known as [[Developmental Biology - Somite Development - Anatomy & Physiology|Somites]]. Somites are transient structures that will give rise to cells of the vertebrae and ribs, dermis of the dorsum, skeletal muscle of the body wall, back and limbs.
