Final answer:
A) Corneum, Lucidum, Granulosum, Spinosum, Basale
The five layers of the epidermis from superficial to deep are: Stratum Corneum, Stratum Lucidum, Stratum Granulosum, Stratum Spinosum, and Stratum Basale, with the correct sequence corresponding to Corneum, Lucidum, Granulosum, Spinosum, Basale.
Step-by-step explanation:
The five layers of the epidermis, from superficial to deep, are:
- Stratum Corneum
- Stratum Lucidum
- Stratum Granulosum
- Stratum Spinosum
- Stratum Basale
The correct sequence using the provided hint 'Can Little Girls Surpass Boys' corresponds to the answer A) Corneum, Lucidum, Granulosum, Spinosum, Basale. The epidermis is connected with the dermis by the basement membrane. Stratum Basale is the deepest layer, composed of basal cells which are stem cells that divide to form new keratinocytes.
Stratum Corneum, the most superficial layer of the epidermis, is exposed to the external environment and consists of dead cells that shed periodically. Underneath the stratum corneum and only present in thick skin (on the palms of the hands and soles of the feet) is the stratum lucidum. Below the stratum lucidum is the stratum granulosum where keratinocytes start to die, below which is the stratum spinosum. This layer is the thickest and contains spiny keratinocytes and Langerhans cells. Finally, the deepest bottom layer is the stratum basale, containing basal cells and melanocytes which produce melanin.
