Final answer:
In the reticular layer of the skin, you can often find sweat and sebaceous glands, hair follicles, and networks of collagen and elastin fibers. The correct answer to what else is present in this layer other than pressure receptors is hair follicles.
Step-by-step explanation:
The reticular layer of the skin is rich in various structures such as sweat glands, sebaceous glands, and hair follicles. It is the deeper layer of the dermis that provides strength and elasticity due to its abundant collagen and elastin fibers. This layer also contains the glands that are essential for regulating body temperature and skin moisture, as well as for protecting the body by secreting oils that waterproof the skin and hair.
The reticular layer does not contain lymph nodes, red blood cells, or bone marrow. However, it is closely associated with lymphatic vessels that drain to lymph nodes, and the dermis overall has a rich blood supply that includes red blood cells within its vessels. While bone marrow is vital for hematopoiesis - the creation of blood cells - it is located within the spongy bone tissue, not within the skin.
Considering the available options, the correct thing that can typically be found in the reticular layer of the skin, in addition to pressure receptors, is hair follicles (B).
