Step 1: Break Down the Problem

To answer the question, we need to identify the three main types of body membranes from the provided options: vertebral, serous, transitional, cutaneous, and mucous.

Step 2: Relevant Concepts

Body membranes are thin layers of tissue that cover surfaces, line cavities, and separate or connect organs. The three main types of body membranes are:

1. Serous membranes - These secrete a fluid that lubricates the surfaces of organs within the cavities of the body.
2. Mucous membranes - These line body cavities that are open to the exterior and produce mucus for lubrication and protection.
3. Cutaneous membranes - This is the skin, which covers the entire body and protects against the external environment.

Note: Vertebral and transitional are not classified as the main types of body membranes.

Step 3: Analysis and Detail

• Serous membranes: Include the pleura (lining the thoracic cavity) and pericardium (surrounding the heart).
• Mucous membranes: Found in areas such as the respiratory tract and digestive tract.
• Cutaneous membranes: Comprises the epidermis and dermis of the skin.

Step 4: Verify and Summarize

From the analysis above, the correct selections are:

1. Serous
2. Mucous
3. Cutaneous

These are indeed the three main types of body membranes.

Final Answer

The three main types of body membranes are:

1. Serous
2. Mucous
3. Cutaneous
