Which of the following refers to disorders of the sudoriferous glands?

The correct answer highlights a group of specific conditions that are directly related to the function and disorders of the sudoriferous glands, commonly known as sweat glands. Anhidrosis, bromidrosis, hyperhidrosis, and miliaria rubra represent various ways in which these glands can malfunction or be affected by external factors.

Anhidrosis refers to the inability to sweat normally, which can lead to overheating and heat-related illnesses. Bromidrosis involves the abnormal body odor due to excess sweating and bacterial breakdown of sweat. Hyperhidrosis is characterized by excessive sweating, which can be localized or generalized throughout the body, often causing discomfort and social issues. Miliaria rubra, also known as heat rash, occurs when sweat ducts become blocked and lead to red, itchy bumps on the skin.

While the other conditions mentioned in the options are significant in their own right, they do not pertain specifically to disorders of the sudoriferous glands. Acne vulgaris is related to sebaceous glands and the oil production in the skin, and blistering does not exclusively target sweat glands. Thus, the answer encompassing all relevant disorders related to the sudoriferous glands illustrates a comprehensive understanding of conditions affecting these glands.
