Which inflammatory disorder of the sudoriferous gland is caused by excessive heat?

Prickly heat, also known as heat rash or miliaria, is an inflammatory condition of the sudoriferous (sweat) glands that occurs as a response to excessive heat. This disorder is characterized by red, itchy, and sometimes painful bumps on the skin due to blocked sweat ducts. When the body overheats, sweat can become trapped under the skin, leading to inflammation in the affected areas. This condition is common in warm, humid environments and often affects areas where sweat accumulates, such as the neck, chest, and back.

Psoriasis is a chronic autoimmune condition that causes skin cells to multiply rapidly, leading to thick, scaly patches, but it is not directly related to heat exposure. Athlete's Foot is a fungal infection that occurs on the feet and has no connection to the functioning of sweat glands in response to heat. Eczema, while it can be triggered by various factors including heat, is primarily characterized by dry, inflamed skin and is often related to genetic and environmental factors rather than being solely a response to heat.

Thus, the association of prickly heat with excessive heat exposure makes it the correct answer to the question regarding the inflammatory disorder of the sudoriferous glands.
