Anatomy & Physiology Integumentary #10
Which disorder of the integumentary system is caused by a fungus?
Impetigo is a contagious skin condition that appears as a rash on the skin. It is caused by bacteria, not a fungus.
Albinism is caused by a melanin defect that causes an abnormal coloration of the skin and hair. It is not caused by a fungus.
- Tinea pedis
Tinea pedis, or Athlete’s foot, is a fungal infection of the skin.
- Herpes labialis
Herpes labialis, often referred to as cold sores, is a viral (not fungal) infection that typically affects the lips.
Skin disorders, which decrease the skin’s ability to protect, may be caused by pathogens (e.g., bacteria, fungi, virus, etc) or other many issues.
One of the primary functions of the skin is protection against microorganisms. Tinea pedis, or Athlete foot’s foot is caused by a fungus and can negatively impact the skin’s ability to provide other methods of protection. This can, therefore, increase the risk for dehydration, mechanical trauma, and damage from ultraviolet (UV) radiation.
Test Taking Tip
Consider each skin condition and ask yourself what is the cause in order to answer this question correctly.
