Prickle cell layer

The stratum spinosum (or spinous layer/prickle cell layer) is a layer of the epidermis found between the stratum granulosum and stratum basale. This layer is composed of polyhedral keratinocytes . [3] [4] These are joined together with desmosomes . [3 the layer of polyhedral cells in the epidermis; shrinkage artifacts and adhesion of these cells at their desmosomal junctions gives a spiny or prickly appearance. Synonym (s): prickle cell layer, spinous layer.

Stratum spinosum - Wikipedi

the prickle cell layer (stratum spinosum), in which they are knit together by plaquelike structures called desmosomes. Next they move through a granular layer (stratum granulosum), in which they become laden with keratohyalin, a granular component of keratin. Finally the cells flatten, lose their nuclei, and form the stratu Prickle cells also provide the superstructure of this layer of skin. The prickles, or desmosomes, radiating from each cell are the points of attachment that join cell to cell; mitosis, or cell division, occurs infrequently in this layer The outer layer of skin is called the epidermis and, from deep to superficial, is composed of 5 sub-layers which are known as; Horny Layer. Clear layer. Granular layer. Prickle-cell layer. Basal Layer The epidermis of the top layer of the skin is divided into five layers: Basal lamina: the supporting membrane that sits between the epidermis and the dermis. Stratum basale: basal cell layer of dividing keratinocytes and unipolar stem cells. Stratum spinosum: prickle cell layer of a different form.

The prickle cell layer (stratum spinosum) is the next layer (8-10 layers of cells). The cells in these layers have lots of desmosomes, which anchor the cells to each other, and contain thick tufts of intermediate filaments (keratin) Typical hemidesmosomes occur along the abluminat aspect of the basal cells. Desmosomes are most frequent in the prickle cell layer, where desmosome fields may occur, and in the lower functional cell layer. Their fate in the upper layers is not known. Gap junctions are few in the basal cell layer and rare in the most superficial layers The layer of the epidermis consists of 5 sub-layers of keratinocyte cells. These cells are produced in the innermost basal layer and migrate up towards the surface of the skin. As they do, they mature in shape and composition, becoming filled with keratin
