Malpighian layer
Encyclopedia
The Malpighian layer of the skin
is a term that is generally defined as both the stratum basale
and stratum spinosum
as a unit, although it is occasionally defined as the stratum basale
specifically. Also, the term is occasionally used synonymously as the prickle cell layer (although prickle cell layer generally is defined as the stratum spinosum
specifically) or to designate a part of the stratum corneum
.
It is named after Marcello Malpighi

Skin
-Dermis:The dermis is the layer of skin beneath the epidermis that consists of connective tissue and cushions the body from stress and strain. The dermis is tightly connected to the epidermis by a basement membrane. It also harbors many Mechanoreceptors that provide the sense of touch and heat...

The stratum basale is the deepest layer of the five layers of the epidermis, which is the outer covering of skin in mammals. The stratum basale is a continuous layer of cells...
and stratum spinosum
Stratum spinosum
The stratum spinosum is a layer of the epidermis found between the stratum granulosum and stratum basale. This layer is also referred to as the "spinous" or "prickle-cell" layer. This appearance is due to desmosomal connections of adjacent cells. Keratinization begins in the stratum spinosum....

Stratum corneum
The stratum corneum is the outermost layer of the epidermis, consisting of dead cells that lack nuclei and organelles. The purpose of the stratum corneum is to form a barrier to protect underlying tissue from infection, dehydration, chemicals and mechanical stress...
