Verified step by step guidance

Understand the anatomy of the integumentary system: The integumentary system includes the skin, hair, nails, and associated glands. Hair follicles are specialized structures within the skin that produce hair.

Identify the components directly associated with a hair follicle: Hair follicles are closely connected to certain structures, such as sebaceous glands and arrector pili muscles, which play roles in lubrication and movement of the hair.

Analyze the options provided: Sweat pores are openings for sweat glands and are not directly associated with hair follicles. The stratum corneum is the outermost layer of the epidermis and does not directly interact with hair follicles.

Focus on the correct associations: Sebaceous glands secrete sebum (oil) into the hair follicle to lubricate the hair and skin. Arrector pili muscles are small muscles attached to hair follicles that cause the hair to stand upright when contracted (e.g., during goosebumps).

Conclude the reasoning: Based on the anatomy and function of the integumentary system, sebaceous glands and arrector pili muscles are directly associated with hair follicles, while sweat pores and the stratum corneum are not.
