Neural Tube
The neural tube is the structure in mammalian embryos that develops into the brain and spinal cord. It forms from the ectoderm layer during development and gives rise to the central nervous system.
Neural tube
The notochord is a flexible rod-like structure found in embryos of chordate animals, including humans. It provides support and helps define the axis of the body. In many vertebrates, the notochord develops into part of the spinal column.
The neural tube develops into the vertebrate spinal cord. It forms early in embryonic development from a flat sheet of neural ectoderm that rolls into a tube, eventually differentiating into the brain and spinal cord.

In vertebrates, a backbone of bone or cartilage segments called vertebrae develops around the notochord. Hope i could help

These are the vessicles in the terminal button that contain the neurotransmitters.
The first part to develop in a human is the neural tube, which eventually develops into the brain and spinal cord. This typically occurs during the third week of gestation.
