The anterior intercostal arteries are branches of the internal thoracic (upper six spaces) and musculophrenic (seventh to ninth spaces) arteries. A) False B) True

Understand the Problem

The question is presenting a statement about the anterior intercostal arteries and asking if it is true or false. It tests the user's knowledge of human anatomy and blood vessel branching.

More Information

The internal thoracic artery supplies the anterior intercostal arteries for the first six spaces, while the musculophrenic artery supplies the seventh to ninth spaces. This distribution ensures an adequate blood supply to the anterior thoracic wall.

Tips

A common mistake is to confuse the roles of the posterior and anterior intercostal arteries. Ensure you focus on the specific arteries being asked about.
