Verified step by step guidance

Step 1: Begin by understanding the integumentary system. The integumentary system is primarily responsible for protecting the body and includes structures such as the skin, hair, nails, and associated glands.
Step 2: Break down the components of the skin. The skin is composed of three main layers: the epidermis (outermost layer), the dermis (middle layer), and the hypodermis (subcutaneous layer). These layers are integral to the integumentary system.
Step 3: Identify the thyroid gland. The thyroid gland is part of the endocrine system, not the integumentary system. It is responsible for producing hormones that regulate metabolism, growth, and development.
Step 4: Compare the listed options. Dermis, epidermis, and hypodermis are all components of the integumentary system, while the thyroid gland is not.
Step 5: Conclude that the thyroid gland is the correct answer to the question, as it is not a component of the integumentary system.
