The term "Axillary Arteries" refers to the arteries located in the axilla region of the body. The word "Axillary" is spelled [æk'sɪləri] in IPA phonetic transcription. The stress is on the second syllable, which is pronounced as "suh-luh-ree". The first syllable is pronounced as "ak" with a short "a" sound followed by a glottal stop. The second syllable starts with a "s" sound, followed by a "l" sound, and ends with a short "i" sound. The third syllable is pronounced as "ree", with a long "e" sound at the end.
Axillary arteries are major blood vessels located in the upper limbs of the human body. They are part of the circulatory system and play a crucial role in supplying oxygenated blood to the arms. The axillary arteries extend from the outer border of the first rib to the lower border of the teres major muscle in the upper arm.
These arteries originate from the subclavian arteries, which are the main vessels that provide blood to the upper body. As they pass through the armpit region, the axillary arteries give rise to numerous branches that supply blood to various structures in the arm, such as the muscles, bones, and joints.
The axillary arteries have three main divisions based on their position in the armpit: the superior (or upper), lateral, and inferior (or lower) divisions. Each division gives rise to specific branches that nourish different parts of the upper limb.
The axillary arteries are responsible for delivering vital nutrients, gases, and other essential substances to the arm tissues. Additionally, these arteries transport waste products to the veins for elimination from the body. The proper functioning of axillary arteries is crucial for maintaining the health and normal functioning of the upper limb.
In summary, axillary arteries are major blood vessels that supply oxygenated blood to the arm. Originating from the subclavian arteries, they extend through the armpit and give rise to several branches, ensuring adequate blood supply to the upper limb.
The word "axillary" comes from the Latin word "axilla", which means "armpit". It is derived from the Proto-Indo-European root "ak", meaning "armpit" or "shoulder".
The term "artery" comes from the Latin word "arteria", which originally meant "windpipe" or "air vessel". It was derived from the Greek word "artēriā", meaning "windpipe" or "pulsating artery".
Therefore, the term "axillary arteries" is a combination of "axillary", referring to the armpit region, and "arteries", which are blood vessels that carry oxygenated blood away from the heart to various parts of the body. The axillary arteries refer to the major arteries in the armpit area that supply blood to the upper extremities.
