What is the anatomical term for the anterior thoracic region on the midline?
Sternal region
What is the anatomical region surrounding the nipple on the anterior thorax?
Mammary region
What is the anatomical region found on superior lateral aspect of the anterior thorax?
Pectoral region
What is the anatomical term for what is commonly called the armpit?
Axilla, axillary region
What is the junction between the manubruim and the body of the sternum?
Sternal angle
What is the imaginary line extending inferior from the middle of the clavicle?
Midclavicular line
What is the imaginary line extending down the lateral aspect of the chest In the axillary region?
Midaxillary line
On the center of the breast what is the cylindrical projection containing numerous openings of excretory ducts that transport milk?
Nipple
What is the pigmented area around the nipple?
Areola
What is the extension of the breast that extends laterally toward the axilla (side boob) ?
Axillary tail/process
What structures give the areola an uneven and grainy appearance?
Areolar glands
What internal structures of the breast extend from the deep fascia overlying the pectoralis major to the skin?
Suspensory ligaments
Tiny ducts from the alveoli and lobules of the breast merge to form what structures?
Lactiferous ducts
As each lactiferous duct approaches the nipple it expands to form what structure?
Lactiferous sinus
What body cavity arises from a space called the coelom that forms during embryonic development?
Ventral cavity
What muscular partition separates the ventral cavity into two smaller cavities?
Diaphragm
What type of membrane lines the ventral cavity?
Serous membranes
Of the membranes that line the ventral cavity what layer adheres to the internal surface of the body wall?
Parietal layer
Of the membranes that line the ventral cavity what layer adheres to the external surface of the internal organs?
Visceral layer
What is the potential space between the two layers of the membranes lining the ventral cavity?
Serous cavity
What is the function of serous fluid?
Lubrication
What body cavity is surrounded by the ribs and vertebral column and holds the heart and lungs?
