A) Stratum corneum
B) Stratum granulosum
C) Stratum basale
D) Stratum spinsosum
Solution
Solution Steps
Step 1: Identify the Layers of the Epidermis
The epidermis consists of several layers, from the outermost to the innermost:
Stratum corneum
Stratum lucidum (only in thick skin)
Stratum granulosum
Stratum spinosum
Stratum basale
Step 2: Analyze the Image
The image shows a cross-section of the epidermis with the topmost layer labeled as "LAYER?" and the bottommost layer labeled as "CELL2".
Step 3: Determine the Labeled Layer
The topmost layer in the epidermis is the stratum corneum, characterized by its multiple layers of dead, flattened keratinocytes.
Final Answer
The layer of the epidermis marked in the picture with "LAYER?" is:
A) Stratum corneum
