Quick, free thorax labeling quiz to test your anatomy recall. Instant results.
Use this thoracic cage labeling quiz to practice naming each rib, the sternum, and key landmarks like the sternal angle and costal margin. Build quick recall for labs and exams, then keep going with a rib labeling quiz and a thoracic vertebrae quiz. Get instant results to see what to review next.
Study Outcomes
- Identify Rib Structures -
Understand the names and positions of all 12 pairs of ribs to accurately answer rib cage anatomy quiz questions.
- Recall Sternum Anatomy -
Describe the manubrium, body, and xiphoid process and distinguish their roles within the bones of the thorax.
- Differentiate Rib Categories -
Classify true, false, and floating ribs based on their attachments and anatomical landmarks in the thorax.
- Locate Key Thoracic Landmarks -
Pinpoint and explain the significance of landmarks such as the sternal angle, costal margin, and thoracic inlet.
- Apply Knowledge in Clinical Contexts -
Use your comprehension of thoracic landmarks and rib anatomy to solve practical scenarios and prepare for exams.
Cheat Sheet
- Rib Classification and Numbering -
Ribs 1 - 7 are "true" (direct sternal attachments), ribs 8 - 10 are "false" (attach via shared costal cartilage), and ribs 11 - 12 are "floating" (no anterior attachment). Use the mnemonic "True at Seven, False at Ten, Floating at Twelve" to recall this quickly. (Source: Gray's Anatomy, University of Michigan Anatomy Dept.)
- Sternal Anatomy and Angle of Louis -
The sternum comprises the manubrium, body, and xiphoid process; the sternal angle (Angle of Louis) marks the junction of manubrium and body. This landmark corresponds to the second rib's attachment and the T4 - T5 vertebral level, vital for rib counting in the thorax anatomy quiz. (Source: NIH MedlinePlus, Stanford Med Ed.)
- Costovertebral and Costotransverse Joints -
Each rib head articulates with the superior and inferior demifacets of two adjacent thoracic vertebral bodies, while the tubercle meets the transverse process. Remember "head to bodies, tubercle to transverse" to solidify these rib cage anatomy quiz concepts. (Source: Journal of Anatomy, University College London.)
- Thoracic Vertebrae Landmarks -
Thoracic vertebrae feature long, downward”sloping spinous processes and paired demifacets on their bodies for rib articulation. Identify T1 by its full superior costal facet and T10 - T12 by single facets; this aids in mapping thoracic landmarks accurately.

- Surface Landmarks and Clinical Relevance -
Key surface lines include the midsternal, midclavicular, and anterior axillary lines; the 5th intercostal space at the anterior axillary line is ideal for chest tube insertion. Visualizing these landmarks bridges academic knowledge with real”world procedures in obstetrics and trauma care. (Source: American College of Surgeons, BMJ Open.)
