Final answer:
The skin layer underneath the stratum germinativum (stratum basale) is the A.papillary layer. It is part of the dermis and is followed by the denser reticular layer. The basement membrane connects the epidermis and the dermis.
Step-by-step explanation:
The skin layer just beneath the stratum germinativum or stratum basale is the papillary layer. The stratum basale is the deepest epidermal layer which attaches the epidermis to the basal lamina. Directly underneath, the layers of the dermis begin with the papillary layer, characterized by finger-like projections known as dermal papillae that extend into the epidermis, strengthening the connection between the epidermis and dermis.
The reticular layer lies beneath the papillary layer and is composed of dense, irregular connective tissue. This layer has an abundant vascular supply and nerve supply, and it is responsible for the strength and elasticity of the skin, with collagen and elastin fibers woven throughout.
The basement membrane serves as the bond between the epidermis and dermis, specifically located between the stratum basale and the underlying dermal layers. If someone were to cut themselves and bleed, they would need to penetrate through the epidermis and into the dermis, which includes both the papillary and reticular layers.
