Transcript text: The papillary layer of the dermis consists of areolar tissue containing numerous collagen and elastic fibers. Folds in the tissue are called
reticular papillae
dermal papillae
hair follicles
sebaceous glands
Solution
The answer is the second one: dermal papillae.
Explanation for each option:
Reticular papillae: This term is not typically used in the context of skin anatomy. The reticular layer is a deeper part of the dermis, but it does not have structures called "reticular papillae."
Dermal papillae: Correct. These are the folds or projections in the papillary layer of the dermis. They interlock with the epidermis and are responsible for the unique patterns of fingerprints.
Hair follicles: These are structures in the skin from which hair grows, but they are not folds in the papillary layer.
Sebaceous glands: These are oil-producing glands associated with hair follicles, not folds in the papillary layer.
Summary: The folds in the tissue of the papillary layer of the dermis are called dermal papillae.
