What does the musculophrenic artery supply?

Gross anatomy The musculophrenic artery runs along the costal slips of the diaphragm. It supplies the 7th, 8th and 9th intercostal spaces with paired anterior intercostal arteries, as well as fine branches that supply the superior part of the anterior abdominal wall.

Where does the Pericardiophrenic artery come from?

Location. The pericardiacophrenic artery branches from the internal thoracic artery. It accompanies the phrenic nerve between the pleura and pericardium, to the diaphragm. This is where both the artery and the phrenic nerve are distributed.

What does the internal thoracic artery split into?

The internal thoracic artery, aka the internal mammary artery, supplies the breast and the anterior chest wall. When it reaches the sixth or seventh intercostal cartilage, it divides into two branches, the musculophrenic and the superior epigastric arteries.

Is the phrenic nerve somatic or visceral?

The phrenic nerve carries somatic efferent fibers to the diaphragm and visceral afferent fibers from its region of distribution.

Does the Musculophrenic artery supply the diaphragm?

The musculophrenic artery is a distal branch of the internal thoracic artery….Musculophrenic artery.

What artery gives rise to the highest intercostal artery?

The supreme intercostal artery (highest intercostal artery or superior intercostal artery) is an artery in the human body that usually gives rise to the first and second posterior intercostal arteries, which supply blood to their corresponding intercostal space.

What artery supplies the diaphragm?

Blood Supply and Lymphatics The blood supply to the diaphragm is from the superior phrenic, musculophrenic, inferior phrenic, pericardiacophrenic, and lower internal intercostal arteries. The superior phrenic arteries arise from the thoracic aorta.

What muscles does the internal thoracic artery supply?

They supply the intercostal, pectoral muscles and the adjacent skin, anastomosing with their posterior counterparts near the posterior trunk. Perforating branches stem from the medial aspects of the internal thoracic artery.

Are there two internal thoracic arteries?

After passing the sixth intercostal space, the internal thoracic artery splits into the following two terminal branches: Musculophrenic artery – roughly follows the costal margin. Superior epigastric artery – continues the course of the internal thoracic artery, travelling downward into the abdominal wall.

What irritates the phrenic nerve?

Phrenic nerve irritation If your phrenic nerve becomes irritated or damaged, you may lose the ability to take automatic breaths. The condition can be caused by a spinal cord injury, physical trauma, or surgical complications. With phrenic nerve irritation, you might also experience: hiccupping.

Where does the pericardiophrenic artery supply the diaphragm?

It runs with the phrenic nerve and pericardiophrenic vein between the pleura and the pericardium , supplying the pericardium and the diaphragm . 1. Kenneth Saladin. Human Anatomy.

Where are the musculophrenic and superior phrenic arteries located?

It anastomoses with the musculophrenic and superior phrenic arteries. On their course through the thoracic cavity, the pericardiacophrenic arteries are located within and supply the fibrous pericardium. Along with the musculophrenic arteries, they also provide arterial supply to the diaphragm. ^ Drake, Richard.

Where does the pericardiacophrenic artery and vein meet?

The pericardiacophrenic artery and vein make up, with the phrenic nerve, the pericardiacophrenic neurovascular bundle. The vessels pass through superior thoracic aperture into the superior mediastinum and course along the pathway of the phrenic nerve anterior to the lung roots.

Where are the vessels of the pericardium located?

The vessels are located between the fibrous pericardium and the parietal pleura in the middle mediastinum and extend inferiorly onto the dome of the diaphragm. The pericardiacophrenic artery supplies blood to the pericardium, diaphragm, and phrenic nerve.
