What layer of the dermis contains the lymph glands?

1. Papillary layer

2. Reticular layer

3. Epidermal layer

4. Subcutaneous layer

The correct answer is: Reticular layer

The reticular layer of the dermis is the correct choice as it contains the lymph glands. This layer is the deeper and thicker part of the dermis, providing strength and elasticity to the skin. It is rich in collagen and elastin fibers, making it crucial for skin support and resilience. Along with lymphatic vessels, the reticular layer houses sweat glands, sebaceous (oil) glands, and hair follicles, playing a vital role in the skin's functionality and overall health. The papillary layer, while important and located above the reticular layer, primarily contains thin collagen fibers and is responsible for the creation of fingerprints. It is less involved in housing significant structures like lymph glands. The epidermal layer is the outermost skin layer and does not contain lymph glands, as its primary function is to act as a barrier and facilitate the skin's protective role. The subcutaneous layer, situated beneath the dermis, primarily consists of fat and connective tissue but also does not contain lymph glands. Instead, its primary function is to insulate the body and cushion underlying structures. Thus, the reticular layer is distinguished by its vital role in housing lymphatic vessels, making it the correct answer.
