The primary difference between stratum basale and stratum corneum indicates that stratum basale is the bottomless coating of the epidermis. In contrast, the stratum corneum is the most elevated coating of the epidermis. The skin is made up of three coatings which include dermis, epidermis, and hypodermis. Epidermis is the skin’s most outer coating, and it safeguards from the incursion of materials into the human body. However, the epidermis consists of many coatings related to the stratum basale, stratum spinosum, stratum lucidum, stratum granulosum, and stratum corneum. The stratum basale is the bottomless coating of the skin’s epidermis, whereas the stratum corneum is the most elevated coating of the skin’s epidermis.
What is Stratum Basale?
Stratum basale is described as the bottomless coating of the epidermis on the skin. It is as well defined as stratum germinativum. The basal lamina’s cellar membrane disconnects the stratum basale from the dermis. However, hemidesmosomes connect the stratum basale to the cellar membrane. These epidermis coatings consist of mitotically vigorous stem cells with cuboidal to columnar structures. These cuboidal to columnar cells are connected, and the excessive stratum spinosum coating cells by desmosomes and hemidesmosomes. The nucleus in these cells is wide and elliptic. The nucleus takes over a lot of the cell area. However, these cells tenaciously create keratinocytes. Stratum basale as well consists of melanocytes. There are two major processes of the stratum basale. This has to do with the expansion and extension of the epidermis to the dermis. Stratum basale as well possesses medical importance. This is since basal cell cancers, which the basal cell carcinoma, often take place in this epidermis coating. Nasal cell cancers record for approximately 80 percent of every skin cancer.
What is Stratum Corneum?
The stratum corneum is the most elevated coating of the skin’s epidermis. It consists of twenty to thirty cell coatings. Also, the stratum corneum consists of keratin and horny scales. The horny scales consist of lifeless keratinocytes described as anucleate squamous cells. This coating generally differs in viscosity. However, this coating possesses dead keratinocytes, which discharge defensins. Defensins are defined as the area of the first human immune defense structure. The stratum corneum operates different defensive and other critical physiological processes. These processes involve mechanical shear, effect resistance, hydration control, microbial expansion, and incursion regulation and control. Furthermore, its processes also have to do with beginning inflammation via cytokine activation and dendritic cell activation and performing as a demanding permeability coating to poisons, annoyance, and allergens. Also, several ailments are connected with difficulties in this coating which has to do with hyperkeratosis. Hyperkeratosis is an elevated viscosity of the stratum corneum.
Difference Between Stratum Basale and Stratum Corneum
The stratum basale is described as the bottomless coating of the epidermis, whereas the stratum corneum is the most elevated coating of the epidermis. Hence, this is the primary difference between stratum basale and stratum corneum. Also, stratum basale possesses a lone cell coating, whereas stratum corneum has twenty to thirty cell coatings. However, stratum basale possesses melanocytes, whereas stratum corneum possesses lifeless keratinocytes that discharge defensins.
