PRICKLE CELLS Meaning and
Definition
-
Prickle cells, also known as spiny cells or spinous cells, refer to a type of epithelial cell found in the outermost layer of the skin, known as the stratum spinosum. They are named prickle cells due to the presence of spiny projections, known as desmosomes, that extend from their surface. These desmosomes form strong connections with neighboring prickle cells, creating a tightly interconnected layer within the epidermis.
The main function of prickle cells is to provide mechanical support and strength to the skin. Their spiny projections allow them to anchor to adjacent cells, forming a network that reinforces the overall structure of the epidermis. This provides an important barrier against physical injury, preventing the skin from being easily torn or damaged.
Additionally, prickle cells play a crucial role in maintaining the integrity of the skin barrier. The desmosomes present on their surface facilitate strong cell-to-cell adhesion, preventing the entry of pathogens and foreign substances into the underlying tissues. Furthermore, prickle cells are involved in maintaining the proper hydration of the skin by regulating the movement of water and molecular nutrients through their cell membranes.
Overall, prickle cells are essential components of the epidermis, serving as key contributors to the skin's mechanical strength, barrier function, and maintenance of homeostasis.

Etymology of PRICKLE CELLS
The term "prickle cells" is commonly used in the field of dermatology and refers to a specific layer of cells found in the epidermis, which is the outermost layer of the skin. The etymology of "prickle cells" can be understood by looking at the origins of each component of the term.
1. Prickle: The word "prickle" comes from the Middle English "prikel" which is derived from the Old English "pricel". It originally meant a sharp pointed object such as a thorn or spine. The term later evolved to also describe a tingling or prickling sensation on the skin. In the context of skin cells, the term refers to the spiny or prickly appearance of these cells when observed under a microscope.
2. Cells: The word "cell" has its roots in the Latin word "cella" which means "small room" or "chamber".
