True/False Statements
- The costotransverse joint allows slight movement during respiration.
Answer: False - The posterior longitudinal ligament resists extension and provides support to intervertebral discs.
Answer: False - The vagus nerve (Cranial Nerve X) travels through the thorax and innervates structures such as the heart and lungs.
Answer: True - The thoracic duct drains lymph from the right upper quadrant (right arm, right side of head and neck) into venous circulation.
Answer: False - Swollen lymph nodes can indicate infection or malignancy.
Answer: True - The interchondral joint connects the costal cartilages of adjacent ribs.
Answer: True - The ligamentum flavum connects adjacent spinous processes of vertebrae.
Answer: False - The pulmonary circulation carries oxygenated blood to the lungs and deoxygenated blood back to the heart.
Answer: False - Knowledge of lymph node locations is important for diagnostic procedures like biopsies.
Answer: True - The sympathetic chain ganglia provide parasympathetic innervation to thoracic organs.
Answer: False
