Final answer:
The pineal gland is not found in the integument, which consists of glands like sebaceous, sudoriferous, and mammary glands.
Step-by-step explanation:
The pineal gland is not a gland found in the integument. The integument of mammals includes glands such as sebaceous, sudoriferous (sweat), and mammary glands. Sebaceous glands produce sebum for lubrication and water resistance, while sudoriferous glands produce sweat for thermoregulation and scent communication. Mammary glands produce milk for feeding newborns.
