Keratinocytes are the major cellular components of the epidermis. They are found in the four major epidermal strata: basale, spinosum, granulosum and corneum. Explain the characteristics of and the changes in the keratinocytes as they journey from the deepest to the most superficial epidermal strata.
Which of the following statements are true with regards to epidermal ridges? Select all that apply.
The ridges will grow with the same pattern if the dermis is damaged
If the dermis is damaged, the original ridge pattern will be altered due to scarring
The ridges will grow with the same pattern if the epidermis is damaged
If the epidermis is damaged, the original ridge pattern will be altered due to scarring
If the stratum granulosum is damaged, the original ridge pattern will be altered due to scarring
The ridges will grow with the same pattern if the hypodermis is damaged
