Question

1. which body system do hair, skin, and nails belong to? a) circulatory b) nervous c) integumentary d) glandular 9. although hair is no longer needed for warmth and protection, it still impacts our ______ in significant ways. a) personality b) body temperature c) defenses d) psychology matching 10. use the word bank to match the five main structures of the hair root with their descriptions. one structure will be used twice. word bank: hair bulb, hair follicle, sebaceous glands, arrector pili muscle, dermal papillae contraction of this structure causes the hair to stand up, resulting in \goose - bumps\ found at the base of the hair follicle contains blood vessels that supply nutrients that allow the hair to grow tube - like structure that surrounds the hair root and anchors the hair to the skin or scalp produces a substance called sebum, also known as oil, which lubricates the hair and skin involuntary muscle in the dermis that attaches to the hair follicle cone - shaped elevation at the base of the hair bulb attached to the hair follicle bulb - shaped; contains living cells that will form the hair strand not found on the palms of the hands or the soles of the feet

Explanation:

Hair, skin, and nails are part of the integumentary system which provides protection. Hair can still impact body temperature. For the matching part, recall the functions and locations of hair - root structures: the arrector pili muscle causes hair - standing and is an involuntary muscle attached to the hair follicle; the dermal papillae are at the base of the hair follicle and contain blood vessels; the hair follicle is a tube - like structure; the sebaceous glands produce sebum; the hair bulb is bulb - shaped with living cells.

Answer:

1. C) integumentary
2. B) body temperature

10.

• Contraction of this structure causes the hair to stand up, resulting in "goose - bumps": arrector pili muscle
• Found at the base of the hair follicle: dermal papillae
• Contains blood vessels that supply nutrients that allow the hair to grow: dermal papillae
• Tube - like structure that surrounds the hair root and anchors the hair to the skin or scalp: hair follicle
• Produces a substance called sebum, also known as oil, which lubricates the hair and skin: sebaceous glands
• Involuntary muscle in the dermis that attaches to the hair follicle: arrector pili muscle
• Cone - shaped elevation at the base of the hair bulb: dermal papillae
• Attached to the hair follicle: arrector pili muscle, sebaceous glands
• Bulb - shaped; contains living cells that will form the hair strand: hair bulb
• Not found on the palms of the hands or the soles of the feet: hair follicle, sebaceous glands, arrector pili muscle
