Examples of stratum corneum in the following topics:
-
- The epidermis includes five main layers: the stratum corneum, stratum lucidium, stratum granulosum, stratum spinosum, and stratum germinativum.
- The stratum basale, also called the
stratum germinativum, is the basal (base) layer of the epidermis.
- Once the keratinocytes leave the stratum granulosum, they
die and help form the stratum lucidum.
- From the stratum lucidum, the keratinocytes enter the next
layer, called the stratum corneum (the horny layer filled with cornified cells).
- The cells of the stratum
corneum are also surrounded by lipids (fats) that help repel water as
well.
-
-
- The deepest of the epidermal layers is called the stratum basale or
stratum germinativum.
- The amount of carotene found in the stratum corneum of the
epidermis and the deepest layer of the skin, the hypodermis.
-
- Vitamin D is produced in the two innermost strata of the epidermis, the stratum basale and stratum spinosum.
-
- The blood vessels in the dermis provide nourishment and remove waste from its own cells and from the stratum basale of the epidermis.
-
- This cavity is roofed in by a single stratum of flattened, ectodermal cells called the amniotic ectoderm.
-
- The outer stratum forms a syncytium, which is a layer of protoplasm studded with nuclei but showing no evidence of subdivision into cells (termed the syncytiotrophoblast).
-
- Here, stratum basale
epithelial cells divide via mitosis to form the hair.
