Study Notes
Breast Cancer
- Most common form of cancer in women
- Spreads via lymphatics, vascular channels, and fibrous tissue
- Incisions are radial as ducts maintain a radial course
Cyst (Galactocele)
- May develop with blockade of a lactiferous duct
Peau D'Orange
- Pits of hair follicles appear to be retracted beneath the level of surrounding skin
- Blockage of lymphatic drainage of skin, leading to stagnation of lymph and oedema of skin
Pectoral Region and Breast
- Bones of the pectoral region: include sternum, scapulae, and upper limb
- Muscles between pectoral region, vertebrae, scapulae, and upper limb:
- Trapezius, Latissimus dorsi, Rhomboid major, Rhomboid minor
- Breast position, composition, blood supply, and lymphatic drainage with axillary lymph nodes groups
Muscles Connecting the Upper Limb to the Vertebral Column
- Trapezius, Latissimus dorsi, Rhomboid major, Rhomboid minor, Levator scapulae
- All of the above muscles insert into the medial border of the scapula except Latissimus dorsi
Muscles Connecting the Upper Limb to the Scapula
- Deltoid, Supraspinatus, infraspinatus, Teres major, Teres minor, Subscapularis
- All of the above muscles attach to the greater tuberosity of the humerus except Teres major
