The axilla is an anatomical region under the shoulder joint where the arm connects to the shoulder. It contains a variety of neurovascular structures, including the axillary artery, axillary vein, brachial plexus, and lymph nodes. What is the axillary tail of the breast?
1 - nerve supply to breast from axilla
2 - tail of axillary nerve supplying breast
3 - extension of axilla that includes the breast
4 - expansion of breast tissue ending in axilla
4 - expansion of breast tissue ending in axilla
- enters axilla through an opening in the deep fascia called foramen of Langer
The axilla is an anatomical region under the shoulder joint where the arm connects to the shoulder. It contains a variety of neurovascular structures, including the axillary artery, axillary vein, brachial plexus, and lymph nodes. The axillary tail of the breast, an extension of the tissue of the breast that extends into the axilla is able to enter the axilla through an opening in the deep fascia called foramen of Langer. What is the foramen of Langer?
1 - opening of the axilla
2 - opening in deep pectoralis fascia
3 - opening in superficial fascia
4 - opening at sternal notch
2 - opening in deep pectoralis fascia
- present at the level of the third intercostal space
The axilla is an anatomical region under the shoulder joint where the arm connects to the shoulder. The axillary tail of the breast, an extension of the tissue of the breast that extends into the axilla is able to enter the axilla through an opening in the deep fascia called foramen of Langer, an opening in the deep pectoralis fascia, present at the level of the third intercostal space. What is the importance of this site?
1 - breast attachment site
2 - site where breast reconstruction occurs
3 - 70% of lymph vessels drain breast into axilla
4 - nerves for breast pass through
3 - 70% of lymph vessels drain breast into axilla
- contains neurovascular structures, axillary artery, axillary vein, brachial plexus, and lymph nodes
The skin of the mammary gland has 2 main parts that can be visually seen and are important for breast feeding. What are these 2 areas called?
1 - nipple and areola
2 - nipple and labia majora
3 - labia minora and areola
4 - areloa and labia major
1 - nipple and areola
The areola is the pigmented area on the breast around the nipple. What is the function of the areola?
1 - holds nipple in place
2 - secretes oil around the nipple to reduce friction
3 - supplies innervation to the nipple
4 - supplied blood vessels to the nipple
2 - secretes oil around the nipple to reduce friction
What is the difference between stroma and parenchyma?
- parenchyma = functional tissue of an organ
- stroma = structural/supportive tissue of an organ
The stroma of the breast is composed of 2 main components, what are they?
1 - adipose tissue
2 - fibrous connective tissue
The stroma of the breast is composed of 2 main components, adipose tissue and fibrous connective tissue. The fibrous connective tissue of the breast separates the fatty lobules and ensures firm attachment of the adipose tissue to the dermis and deep fascia. What are these fibrous connective tissue organisations called?
1 - ligaments of cooper
2 - ligaments bouchard
3 - ligamentous longus
4 - trigeminal ligaments
1 - ligaments of cooper
What are mammary glands composed of?
- each breast contains aprox 12-20 lobes embedded in fat
- each lobe contains smaller structures called lobules or globules
- globules contain alveoli (hollow sacs)
The mammary glands are composed of aprox 12-20 lobes embedded in fat, where each lobe contains smaller structures called lobules or globules that contain alveoli (hollow sacs). What is the importance of these hollow sacs and what cells are they composed of?
1 - cuboidal cells secreting prolactin
2 - epithelial cells secreting oxytocin
3 - epithelial cells producing milk
4 - epithelial cells producing prolactin
3 - epithelial cells producing milk
- secrete milk that collects in the alveoli
The mammary glands are composed of aprox 12-20 lobes embedded in fat, where each lobe contains smaller structures called lobules or globules that contain alveoli (hollow sacs). The alveoli are lined by mammary secretary epithelial cells which secrete milk that collects in the alveoli. Select the correct path that the milk produced takes to the nipple:
1 - alveoli - lactiferous ducts - lactiferous sinus - nipple
2 - alveoli - lactiferous sinus - lactiferous ducts - nipple
3 - alveoli - lactiferous ducts - nipple
4 - alveoli - lactiferous sinus - nipple
1 - alveoli - lactiferous ducts - lactiferous sinus - nipple
Label the image of the breast using the labels below:
- lobe
- lactiferous duct
- lactiferous sinus
- areola
- lobules
Label the image of the breast using the labels below:
- lobe
- areola
- lactiferous sinus
- lactiferous duct
- lobules
The stroma of the breast is composed of 2 main components, adipose tissue and fibrous connective tissue. The fibrous connective tissue of the breast separates the fatty lobules and ensures firm attachment of the adipose tissue to the dermis and deep fascia. These fibrous connective tissue organisations are called ligaments of cooper. What is the importance of the ligaments of cooper clinically?
1 - breast become saggy if they are pathological
2 - breast become very tight if pathological
3 - shrivel up with dimples resembling an orange peel
4 - shrivel up and change their colour to orange
3 - shrivel up with dimples resembling an orange peel
- if ligaments of cooper are affected by pathology such as cancer they can contract and shrivel up
- can present as early marker of pathology with dimples on skin and retracted nipple
- looks like an orange and is therefore called peau d’orange
Which lymph does aprox 70% of the lymph from the breast tissue drain into?
- via axilla tail of the breast into the axillary lymph node
Sentinel Lymph Node is the 1st lymph node where cancer is likely to spread from primary tumour. What is a Sentinel Lymph Node Biopsy?
- a biopsy of the sentinel lymph nodes (first lymph node a cancer is likely to spread to)
- sit between the breast tissue and the axillary lymph node
What is a Sentinel Lymph Node?
1 - first lymph node discovered near the breast tissue
2 - site unaffected by cancers
3 - location where axilla tail drains into from the breast
4 - 1st lymph node where cancer is likely to spread from primary tumour
4 - 1st lymph node where cancer is likely to spread from primary tumour
A Sentinel Lymph Node Biopsy (SLNB) is a biopsy of the sentinel lymph nodes (first lymph node a cancer is likely to spread to) that sits from the cancer and the axillary lymph node. Why would the SLNB be performed?
- identifies if the tumour has metastasised into the lymphatics tissue
What is nipple retraction?
1 - nipples that have not formed
2 - nipples that point inward or are flat
3 - nipples that have discharge
4 - nipples that invert
2 - nipples that point inward or are flat
