Where does the thoracic duct cross the diaphragm?
(The aortic cleft is labeled near the center.) The aortic cleft is a hole in the diaphragm. This is the lowest and furthest of the big holes. It is located approximately at the level of the twelfth thoracic vertebra (T12).
Does the thoracic duct pass through the diaphragm?
The diaphragm separates the abdominal and thoracic cavities, but allows the passage of some structures through its three openings: The inferior vena cava crosses the diaphragm at the level of the opening of the vena cava. … The thoracic duct and azygos vein pass through the opening of the aorta.
What nerves pass through the diaphragm?
The phrenic nerve is a bilateral mixed nerve that originates from the cervical nerves in the neck and descends through the thorax to innervate the diaphragm. This is the only source of motor innervation for the diaphragm, so it plays a decisive role in respiration.
What goes through the chest?
Structures that pass through the thoracic outlet between the thorax and abdomen include the inferior vena cava and esophagus, which pass through the diaphragm, and the abdominal aorta and thoracic duct, which pass through the diaphragm at through the aortic orifice.

Does the trachea cross the diaphragm?
From the downward bifurcation of the trachea, the esophagus passes behind the right pulmonary artery, the left main bronchus, and the left atrium. At this point, pass the diaphragm. The esophagus also covers parts of the semizygotic veins and intercostal veins on the right side.
Where does the sympathetic part pass through the diaphragm?
Internal nerves and the sympathetic chain also cross the diaphragm between the lateral part of each lower leg and joint 13. th rib .
What vein crosses the diaphragm?
Three main structures run through the diaphragm: the esophagus and the two main blood vessels in the lower body, the inferior vena cava and the descending aorta. This is the opening of the inferior vena cava, the opening of the vena cava.
What nervous system innervates the diaphragm?
The phrenic nerve arises from the anterior roots of the third through fifth cervical nerves and is known to innervate the diaphragm. 1 , 2 . The accessory fibers of the cervical segments that connect with the phrenic nerve are common and originate mainly from the subclavian nerve, the ansa cervicalis, and the sternohyoid nerve. 3 .
Does the vagus nerve innervate the diaphragm?
The phrenic nerve is the motor and sensory nerve of the diaphragm. The vagus nerve provides parasympathetic innervation to all organs of the thorax and abdominal cavity. The pathways of these two nerves are similar: both originate in the neck, descend into the mediastinum, and pass through the diaphragm.
What organ of the gastrointestinal tract crosses the diaphragm?
There are three large holes in the diaphragm that allow certain structures to pass between the chest and abdomen. These openings include: Esophageal opening. Through this opening pass the esophagus and the vagus nerve, which control much of the digestive system.
What 2 systems are in the thoracic cavity?
Rib cage. The thoracic cavity is the anterior abdominal cavity of the body, located in the chest of the trunk. It contains important organs of the cardiovascular and respiratory systems, such as the heart and lungs, as well as organs of other systems, such as the esophagus and thymus.
What passes through the thoracic outlet?
Structures that pass through the thoracic outlet between the thorax and abdomen include the inferior vena cava and esophagus, which pass through the diaphragm, and the abdominal aorta and thoracic duct, which pass through the diaphragm at through the aortic orifice.
What goes through the thoracic region?
There are many other small but important intersecting vessels and nerves, and the abnormally large thyroid gland can pass through the thoracic inlet into the superior mediastinum.
