Verified step by step guidance

Understand the three primary germ layers in human development: ectoderm, mesoderm, and endoderm. Each layer gives rise to different tissues and organs.

Identify the role of the ectoderm. The ectoderm is the outermost layer and is responsible for forming structures such as the skin, hair, nails, and the nervous system, including the brain.

Consider the other options: the heart, liver, and kidneys. These organs are derived from the mesoderm and endoderm, not the ectoderm.

Recall that the brain is part of the central nervous system, which originates from the neural tube formed by the ectoderm during early embryonic development.

Conclude that the brain is the major body part derived from the ectoderm, as it is part of the nervous system, which is a key structure formed by this germ layer.
