What type of glands are small tubular structures found in the reticular layer of the skin?

Sudoriferous glands, also known as sweat glands, are indeed small tubular structures located within the reticular layer of the skin. This layer of the dermis is deeper and provides essential support to the epidermis. Sudoriferous glands play a critical role in thermoregulation and cooling the body through the production of sweat, which is essential for maintaining body temperature. Additionally, these glands help in excretion and can also assist in skin hydration.

In contrast, sebaceous glands are associated with hair follicles and primarily produce an oily substance called sebum, which helps to lubricate the skin and hair. Endocrine glands, while involved in hormone production, are not situated in the skin in the same manner as sudoriferous or sebaceous glands. Salivary glands are exocrine glands located in the mouth that produce saliva, not related to the anatomical context of skin layers. Thus, sudoriferous glands are the correct choice as they directly correspond to the question's specifications regarding gland type and location.
