    complex skin structure including hair follicle and sebaceous gland

    The pilosebaceous unit is a complex structure in the skin that includes a hair follicle, a sebaceous (oil) gland, and an arrector pili muscle. This unit is responsible for producing and growing hair, as well as secreting sebum, an oily substance that helps lubricate and protect the skin. Understanding the pilosebaceous unit is crucial for studying conditions like acne and alopecia, which involve disruptions in this system.
