Each of the three primary germ layers will form a different set of specific organs and tissue types in the animal. The ectoderm will form the nervous system, the epithelial cells of the mammary glands, the lens of the eyes, hair, pigment cells and the epidermis of the skin.hese three layers, the endoderm, the ectoderm and the mesoderm, are called the primary germ layers. After gastrulation, the cup-like embryonic stage that contains at least two distinct germ layers is called the gastrula.
Skin: epidermal layers. The skin is the largest organ of the body, with a surface area of 18 square feet. Its two main layers are the epidermis (outer layer) and dermis (inner layer). The epidermis has several strata (layers) that contain four cell types.hen the cells reach the skin surface, they are sloughed off in a process called desquamation. The next layer, the stratum spinosum, consists of spiny prickle cells that interlock to support the skin. The stratum granulosum, the thin middle layer, initiates keratinization (production of keratin).
