Is the axilla part of the breast?
The main regional nodes of the breast are in the axilla (underarm), but also include those the infraclavicular (under the collarbone), supraclavicular (above the collarbone), and internal mammary (beneath the pectoralis muscle) lymph node chains.
What is axilla in breast?
The axilla, more commonly known as the armpit, contains lymph nodes that are involved in breast cancer. Breast cancer can spread to axillary lymph nodes. The staging of breast cancer often involves axillary lymph node biopsy because this is usually the first site where breast cancer spreads.

What is axillary flower?
The axillary bud (or lateral bud) is an embryonic or organogenic shoot located in the axil of a leaf. Each bud has the potential to form shoots, and may be specialized in producing either vegetative shoots (stems and branches) or reproductive shoots (flowers).

What is the difference between axillary and axilla?
The floor, or base, of the axilla is the axillary fascia and its skin on the surface of the axilla, aka the ‘armpit’. The axilla is filled with adipose (fat) and allows passage for: vessels, nerve plexus, lymphatics, and muscles. The muscles include the coracobrachialis, pectoralis minor, and the biceps brachii.
What is the area under the breast called?

What is mean by terminal and axillary?
The terminal bud arises from the tip of the stem and axillary buds arise from the leaf node of the stem. Hence both the terminal and axillary buds arise from the apex (apical meristem). So, the correct answer is ‘Apical meristem’.
Why is it called bolting?
What Is Bolting? Bolting occurs when a crop prematurely grows flower stalks and produces seeds, preventing the plant from bearing a vigorous harvest. Also called “running to seed” or “going to seed,” bolting redistributes a plant’s energy away from the leaves and roots to instead produce seeds and a flowering stem.
What is bolting to seed?
One of the biggest nuisances in the summer vegetable garden is bolting – when crops put on a vertical growth spurt to flower and set seed before the vegetables are ready for harvest. The result is inedible, bitter-tasting leaves or poor-quality produce with little that can be salvaged.
