Question

which are the four successive layers Present
in the integument of mammals​

Answer 1

Answer:

Skin that has four layers of cells is referred to as “thin skin.” From deep to superficial, these layers are the stratum basale, stratum spinosum, stratum granulosum, and stratum corneum. Most of the skin can be classified as thin skin. “Thick skin” is found only on the palms of the hands and the soles of the feet.

Answer 2

The integument of mammals, which refers to the skin and its derivatives, is composed of four successive layers, which are:

Stratum corneum: The outermost layer of the skin, composed of dead, keratinized cells that protect the body from external factors such as water loss and physical damage.

Stratum lucidum: A thin, clear layer found only in certain areas of the body, such as the palms of the hands and soles of the feet. It is composed of flattened, dead cells.

Stratum granulosum: The layer of the skin where the process of keratinization begins, in which cells produce and accumulate the protein keratin, which provides structural support to the skin.

Stratum basale: The innermost layer of the skin, where new skin cells are produced through cell division. These cells gradually move upwards and differentiate into the other layers of the skin.

These four layers work together to provide a protective barrier against external factors, regulate body temperature, and play a role in sensory perception.
