Verified step by step guidance

Step 1: Begin by understanding the integumentary system, which includes the skin (epidermis, dermis, and subcutaneous layer) and its associated structures. Its primary function is to protect the body from external harm, regulate temperature, and provide sensory information.

Step 2: Recognize that the spinal cord is part of the central nervous system and is protected by structures beyond the integumentary system. The spinal cord is housed within the vertebral column, which is part of the skeletal system.

Step 3: Analyze the options provided. The epidermis, dermis, and subcutaneous layer are layers of the skin and do not directly protect the spinal cord. Their role is more related to external protection and insulation.

Step 4: Understand that the vertebral column, composed of vertebrae, surrounds and protects the spinal cord. It acts as a bony shield and provides structural support for the body.

Step 5: Conclude that while the integumentary system provides external protection for the body, the primary protection for the spinal cord is the vertebral column, which is part of the skeletal system and not the integumentary system.
