The outermost, middle, and innermost layers are the ectoderm, mesoderm, and endoderm, respectively.
The number of tissue layers that develop in the embryo is typically three. These three primary germ layers are the ectoderm, mesoderm, and endoderm. Each layer gives rise to specific tissues and structures in the developing organism.
The embryo layer that forms the skin and nervous tissue is the ectoderm. It gives rise to the epidermis of the skin, hair, nails, and the nervous system including the brain and spinal cord. The ectoderm is one of the three primary germ layers that develop during gastrulation in embryogenesis.
Gastrula has cell layers that will later develop into different body structures. The three primary germ layers - ectoderm, mesoderm, and endoderm - are formed during gastrulation and give rise to various tissues and organs in the developing embryo.
In humans, the epidermis is four or five cell layers thick, depending upon the area of skin in question. There is the cornfield layer, the clear layer, granular layer, spinous layer and basal layer.
The skin is made up of three primary layers: the epidermis, the dermis, and the hypodermis (subcutaneous tissue). The epidermis is the outermost layer that provides a barrier to protect against environmental factors, the dermis contains connective tissue, sweat glands, and hair follicles, and the hypodermis stores fat and provides insulation.

The yolk plug of a frog embryo will develop into the endoderm, which is one of the three primary germ layers. The endoderm gives rise to the gastrointestinal tract and associated organs.
Gastrula has cell layers that will later develop into different body structures. The three primary germ layers - ectoderm, mesoderm, and endoderm - are formed during gastrulation and give rise to various tissues and organs in the developing embryo.

Mammalian skin is composed of two primary layers:the epidermis, which provides waterproofing and serves as a barrier to infection; andthe dermis, which serves as a location for the appendages of skin;
Ectoderm
There are actually three layers of skin: the epidermis, the dermis, and the hypodermis.
Melanin is the pigment that helps protect the deepest layers of the epidermis.
In humans, the epidermis is four or five cell layers thick, depending upon the area of skin in question. There is the cornfield layer, the clear layer, granular layer, spinous layer and basal layer.
