Question

What is the name of the four layers in the skin (excluding lucidum)?

1) Epidermis, Dermis, Hypodermis, Stratum corneum
2) Epidermis, Dermis, Hypodermis, Stratum lucidum
3) Epidermis, Dermis, Lucidum, Hypodermis
4) Epidermis, Dermis, Lucidum, Stratum corneum

Answer 1

The four layers of skin, excluding the stratum lucidum, are the epidermis, dermis, hypodermis, and the outermost layer of the epidermis, the stratum corneum. Therefore, the correct answer is option 1.

Step-by-step explanation:

The four layers of the skin, excluding the stratum lucidum, are the epidermis, dermis, and hypodermis. The epidermis itself is composed of four main layers which are, from deepest to most superficial, the stratum basale, stratum spinosum, stratum granulosum, and stratum corneum. For the purposes of the question which among the provided options correctly lists the four layers, the correct answer would be option 1: Epidermis, Dermis, Hypodermis, and Stratum corneum. This is because the epidermis, dermis, and hypodermis are the primary layers of the skin, while the stratum corneum is the outermost layer of the epidermis.
