Horizontally: lateral border of sternum to mid-axillary line. Above: Clavicle Below: 7th to 8th ribs Medially: Midline Posteriorly : to the edge of latissimus dorsi 6. 2nd ribPectoralis majorSkin6th rib Fat 7. Deep relations: 8. Skin: Nipple AreolaParenchymaStroma 9. SkinAreolaNipple Tubercle of Montgomery 10. Parenchyma: Lobes:Lobules- 15 20 in number- Composed of minute glandular Ductulesstructures called lobules- Lobules empty via ductules inlactiferous ducts Lactiferous duct Lactiferous ducts:- Open on to nipple Lactiferous sinus- Contains ampulla near its end(Reservoir of milk or abnormal discharge)Nipple 11. Stroma:Partly fibrous & partly fatty Ligaments of Cooper:- Anchors the breast with skin- Cancer cells may infiltratethese ligaments, so the breastbecomes fixed & contraction ofthe ligaments can cause retractionor puckering (folding) of the skin. 12. Non-lactating Lactating 13. Extremely vascular1. Internal thoracic artery perforating branches2. Axillary artery 1. Lateral thoracic artery 2. Superior thoracic artery 3. Acromiothoracic artery3. Posterior intercostal arteries lateral branchesArteries are distributed in the anterior surface.Posterior surface is relatively avascular. 14.

Superficial veins: drain into Internal thoracicvein & superficial veins of the lower part ofthe neck Deep veins: drain into Internal thoracic ,Axillary & Posterior intercostal veins 16.
