1Which is correct concerning the autonomic nerves?
- AThe cell bodies of preganglionic parasympathetic neurons, the only such fibers in the body, exit the brain in 1 of 4 cranial nerves.
- BAll autonomic pathways utilize a preganglionic neuron to innervate a target tissue.
- CThe parasympathetic division functions as an emergency or catabolic system involved in fight-or-flight response.
- DPreganglionic sympathetic neuron cell bodies are found in the T1 through L2 segments of the spinal cord.
- EThe sympathetic division functions to conserve energy and restore body resources.
2Which is correct concerning the autonomic nerves?
- AAll postganglionic parasympathetic neurons use Acetylcholine as a neurotransmitter.
- BThe phrenic nerve innervates the Heart and Lungs.
- CAll postganglionic sympathetic neurons use Norepinephrine as a neurotransmitter.
- DSympathetics from T1- L2 innervate the Heart and Lungs.
- EAll preganglionic autonomic neurons utilize Norepinephrine as a neurotransmitter.
3Which is correct concerning the innervation of the heart?
- AParasympathetics to the heart slow heartbeat and reduce cardiac output.
- BVisceral pain fibers from the heart courses back to the heart with parasympathetic nerves.
- CSympathetics to the lungs constrict smooth muscle and close the airways.
- DParasympathetics to the heart accelerate and strengthen heartbeat.
- EParasympathetics to the lungs relax smooth muscle and dilate the airways.
4Which is correct about the thorax?
- AThe superior thoracic aperture is bounded in part by the second rib.
- BA plane that extends from the sternal angle intersects the disk between the T4 and the T5 vertebrae.
- CThe sternal angle is found between the body of the sternum and the xiphoid process.
- DThe ribcage contains 7 false ribs that articulate separately with the body of the sternum.
- EThe inferior boundary of the thorax is formed by the 12th rib.
5Which is correct about the thorax?
- AThe heart is found in the superior mediastinum.
- BThe costal cartilages of the second rib do not articulate at the sternal angle.
- CAll ribs consist of bone and cartilage.
- DThe thoracic wall contains 3 true and 7 false ribs.
- EThe costal margin is formed by the floating ribs.
6Which is correct about the thoracic wall?
- AThe fibers of the external intercostal muscle are parallel to those of the internal intercostal muscle.
- BThe transversus thoracis muscle is in the same tissue plane as the external intercostal muscle.
- CThe deepest tissue layer lining the chest wall is a friction reducing membrane.
- DThe main components of the intercostal neurovascular bundle course in the inferior part of an intercostal space.
- EThe internal intercostal muscle fibers attach to the sternum and to the thoracic vertebrae.
7Which is correct about the thoracic wall?
- APosterior intercostal arteries arise from the internal thoracic arteries; anterior intercostals arise from the aorta.
- BA chest tube should be inserted in the inferior part of an interspace.
- CIntercostal muscles in each interspace have a single arterial blood supply.
- DEach intercostal nerve is a dorsal ramus that innervates intercostal muscles and the skin that covers them.
- EIn each interspace, the posterior intercostal vein is inferior to a posterior intercostal artery.
