layers, which provide an envelope containing all the breast tissues. - The
superficial layer is located in the premammary layer. - The deep layer is
located in the retromammary space.


Question 2: What is the smallest functional unit of the breast?
Answer:

Acini


Question 3: Acini are considered the :
Answer:

Milk producing gland


Question 4: Approximately how many units are in each breast?
Answer:

There are hundreds of acini in each breast


Question 5: Each acini gives rise to its own duct, called ____.

,Answer:

The terminal duct


Question 6: What is a TDLU?
Answer:

Terminal duct lobular unit


Question 7: What structures make up the TCLU?
Answer:

Approximately 30 acini (equaling a lobule) and its associated terminal ducts
make up the TDLU.


Question 8: What is the clinical significance of the TDLU?
Answer:

Nearly all breast pathology originates here


Question 9: What is another name for the mammary layer of the
breast?
Answer:

Glandular or parenchymal layer of the breast


Question 10: What is the axillary tail of spence?
Answer:

The portion of glandular tissue that extends from the upper outer quadrant of
each breast into the axillary region

,Question 11: The mammary layer of the breast is composed of
epithelial and stromal tissues. State the function of each tissue
type and name several anatomic structures that make up each
tissue type :
Answer:

acini, TDLU's, lobules, lobes, and any part of the lactiferous ducts (including
the terminal ducts).

invasion from a breast lesion


Question 18: Which quadrant of the breast is glandular tissue
