exercise 6 integumentary system

1. tattoo ink is injected into the skin. do you think the ink is injected into the epidermis or the dermis? what support do you give for your answer? dermis is thicker, has stable structure and less turnover

1. approximately how long does it take for the epidermis to renew itself?

1. what accessory gland secretes an oil-like substance? sebaceous gland

1. what part of the hair is outside of the skin? shaft

Explanation:

Answer:

1. dermis; stable structure and less turnover
2. Approximately 28 days
3. Melanocytes
4. Hypodermis (subcutaneous tissue) is not part of the integument; the correct layer is hypodermis (note: the original marked "hypodermis" as incorrect? Wait, the integumentary system includes epidermis, dermis; hypodermis is subcutaneous, not part. So the wrong one is hypodermis? Wait the question: "Which one of the three: layers (epidermis, dermis, hypodermis) is not part of the integument? Circle the answer." So the answer is hypodermis (circled as in the image, but text answer: hypodermis)
5. Hypodermis (subcutaneous tissue) because it has connective tissue and blood vessels allowing easy injection
6. Sebaceous gland
7. Shaft
