Verified step by step guidance1
Understand the integumentary system: The integumentary system consists of the skin and its associated structures, including the epidermis, dermis, hypodermis, hair, nails, and glands. It serves as a protective barrier and plays roles in sensation, temperature regulation, and excretion.
Review the components listed in the question: The options provided are Periosteum, Dermis, Epidermis, and Hypodermis. Identify which of these are part of the integumentary system.
Clarify the term 'Periosteum': The periosteum is a dense layer of connective tissue that surrounds bones, providing nourishment and serving as an attachment point for tendons and ligaments. It is part of the skeletal system, not the integumentary system.
Confirm the other terms: The dermis, epidermis, and hypodermis are all layers of the skin and are integral components of the integumentary system.
Conclude that the periosteum is NOT a component of the integumentary system, as it belongs to the skeletal system instead.
