Beginner Retromammary Space Quiz

Q1. Where is the retromammary space located?

• Between the lung and visceral pleura
• Between the breast and the deep fascia of the anterior thoracic wall
• Inside the mammary glandular lobules
• Between the sternum and pericardium

Q2. What type of tissue primarily occupies the retromammary space?

• Cardiac muscle
• Hyaline cartilage
• Loose connective tissue
• Compact bone

Q3. What is a major function of the retromammary space?

• Ventilating the lung
• Producing milk
• Allowing mobility of the breast over the thoracic wall
• Moving the upper limb

Q4. Which muscle lies deep to most of the breast and its retromammary plane?

• Masseter
• Biceps brachii
• Pectoralis major
• Rectus femoris

Q5. The retromammary space separates the breast from which underlying structure?

• Endocardium
• Pericardium
• Visceral pleura
• Deep pectoral fascia

Q6. The retromammary space is most closely associated with which organ?

• Esophagus
• Thyroid gland
• Breast
• Heart

Q7. Is the retromammary space normally a large open cavity?

• Yes, it is part of the pleural cavity
• Yes, it normally contains several liters of fluid
• Yes, it is normally filled with air
• No, it is a potential plane containing loose connective tissue

Q8. Which property of loose connective tissue is important in the retromammary space?

• It produces skeletal movement by contraction
• It permits tissue planes to glide over one another
• It conducts air into the lungs
• It forms rigid joints

Q9. What would normally be expected when the breast is moved over the underlying pectoral fascia?

• Movement of the lung with the breast
• Displacement of the sternum
• Some movement of the breast over the fascia
• No movement under any circumstances

Q10. Which statement best describes the retromammary space?

• It is a skeletal muscle beneath the nipple
• It is a loose connective tissue plane that permits breast mobility
• It is a subdivision of the pleural cavity
• It is a milk-producing compartment within the breast
