ال breast ، خلي نمر على كم معلومة تشريحية بسيطة خاف ننسأل بيها ، وهم تفيدنه بفهم كم pathology بعد شويه ممكن تصير بال breast :
اول شغلة هو modified sweat gland و متكون من fibro-fatty tissue و يكون بال superficial fascia فبالتالي هو superficial gland ، مغطى بال skin و بظهره اكو pectoralis fascia و مثبت بيهن عن طريق cooper’s ligament و anatomy مالته كالتالي :
*it extends from the 2nd to the 6th rib and it extends from the sternum to the mid axillary line. Axillary tail passes deep to the deep fascia.
*the nipple protrude forward ,downward, and lateral , at the Level of 4'h intercostal space ,it gets lower by age.
*Areola ; dark area of skin . becomes mote pigmented with pregnancy.
بس ال pectoralis major صايره وره ال breast ؟ لا ال seratous anterior هم موجوده
ال blood supply منين ياخذه ؟ و ال venous drainage & lymph node ؟
Blood supply :
-The lateral thoracic artery, from the 2n part of the axillary artery. -The perforating cutaneous branches of internal mammary artery to the 2nd, 3rd and 4th intercostal spaces. -The lateral branch of the 2nd, 3rd and 4th intercostal arteries. -Pectoral branches of acromiothoracic artery.
Venous drainage:
-The superficial veins drain to the axillary, internal mammary, and intercostal vessels.
-Deep vein accompany the arteries
*Through posterior intercostal veins, venous drainage communicates with paravertebral venous plexus. Therefore, secondaries in vertebrae is common in carcinoma of breast.
لذلك فد شوي نشوف من ضمن ال patient presentation for cancer breast الم بالفقرات …
