Solution
Solution Steps
Step 1: Identify the components marked with numbers
1: This is the basal layer of the epidermis, also known as the stratum basale. The nuclei in this layer are typically large and oval-shaped.
2: This is the spinous layer of the epidermis, also known as the stratum spinosum. The nuclei in this layer are slightly flattened.
3: This is the granular layer of the epidermis, also known as the stratum granulosum. The nuclei in this layer are more flattened and dense.
Step 2: Identify the components marked with numbers (continued)
4: This is the stratum corneum, the outermost layer of the epidermis. This layer consists of dead, flattened cells without nuclei.
5: This is the dermis, the layer beneath the epidermis. It contains connective tissue, blood vessels, and other structures.
6: This is the entire epidermis, which includes all the layers from the stratum basale to the stratum corneum.
Step 3: Describe the shape of the cells in the indicated layers
1 (Stratum Basale): The cells in this layer are columnar or cuboidal in shape.
2 (Stratum Spinosum): The cells in this layer are polygonal and have a spiny appearance due to desmosomes.
3 (Stratum Granulosum): The cells in this layer are flattened and contain keratohyalin granules.
Final Answer
Stratum Basale: Large, oval-shaped nuclei; columnar or cuboidal cells.
