How does the thoracic duct contribute to the lymphatic drainage of the thorax?
The thoracic duct collects lymphatic fluid from the lower body, left upper limb, and left side of the head and neck, draining into the venous system near the junction of the left subclavian and internal jugular veins.

See lessDescribe the arrangement of the costal cartilages in the rib cage.
The costal cartilages of the true ribs directly articulate with the sternum, while those of the false ribs indirectly connect to the sternum or do not connect at all.

See lessWhat is the role of the intercostal nerves in the thorax?
The intercostal nerves innervate the muscles of the intercostal spaces and provide sensory information from the skin and parietal pleura of the thorax.

See lessDescribe the role of the sympathetic nervous system in the thoracic region.
The sympathetic nervous system innervates structures such as blood vessels and glands in the thoracic region, regulating various physiological responses, including the fight-or-flight response.

See lessHow does the costal cartilage contribute to the flexibility of the rib cage?
The costal cartilage allows for slight movement between the ribs and the sternum, enhancing the flexibility of the rib cage during breathing and other movements.

See lessHow does the thoracic vertebrae differ from the lumbar vertebrae in terms of structure?
The thoracic vertebrae have facets on their transverse processes for articulation with the ribs, a feature absent in the lumbar vertebrae.
