1. what degree burn is a partial thickness burn? 1st degree burn 2nd degree burn 3rd degree burn none of the above 26. which of the following is the most common and least harmful skin cancer? basal cell carcinoma squamous cell carcinoma malignant melanoma none of the above 27. all of the following are accessory organs of the integumentary system except: sweat glands sebaceous glands hair nails chemical receptors 28. an inflamed area includes all of the following characteristics except: redness swelling pain scar formation 29. the cell of the epidermis that produces the pigment responsible for skin color is the keratinocytes melanocytes langerhans cells merkel cells 30. another term for oil glands are ___ glands sebaceous sudoriferous endocrine ceruminous

Explanation:

• 25: A partial - thickness burn is a 2nd degree burn. 1st degree burns affect only the epidermis, 3rd degree burns are full - thickness.
• 26: Basal cell carcinoma is the most common and least harmful skin cancer. Squamous cell carcinoma is less common than basal cell, and malignant melanoma is the most dangerous.
• 27: Sweat glands, sebaceous glands, hair, and nails are accessory organs of the integumentary system. Chemical receptors are not.
• 28: Inflammation is characterized by redness, swelling, and pain. Scar formation is a later process in wound healing, not a characteristic of acute inflammation.
• 29: Melanocytes in the epidermis produce melanin, the pigment responsible for skin color. Keratinocytes produce keratin, Langerhans cells are part of the immune system, and Merkel cells are involved in touch sensation.
• 30: Sebaceous glands are also known as oil glands. Sudoriferous are sweat glands, endocrine glands secrete hormones, and ceruminous glands produce earwax.

3. E. chemical receptors
