Blood supply of breast by all except
**Core Concept**
The breast receives its blood supply from a complex network of arteries that branch off from the subclavian artery. The main blood supply to the breast comes from the internal mammary artery and the lateral thoracic artery, with additional contributions from the thoracoacromial and pectoral arteries.
**Why the Correct Answer is Right**
The internal mammary artery, also known as the internal thoracic artery, is a crucial supplier of blood to the breast tissue. It divides into perforating branches that penetrate the pectoral muscle and supply the breast. The lateral thoracic artery also contributes to the blood supply of the breast, particularly to the lateral aspect. Additionally, the thoracoacromial artery, which is a branch of the axillary artery, supplies the breast tissue through its pectoral branch. The pectoral branches of the thoracoacromial and thoracic arteries also contribute to the blood supply of the breast.
