Answer 1

The subclavian artery is renamed as axillary artery after it passes over the lateral border of the first rib.

What is axillary artery?

• The subclavian artery continues as the axillary artery at the lateral aspect of the first rib, serving as the primary artery of the upper extremity.
• The artery has three sections based on its proximity to the pectoralis minor muscle, each of which has six major branches.
• A sizable muscle vessel that passes through the axilla is called the axillary artery.
• It is in charge of delivering oxygen-rich blood to the upper limb as well as to a portion of the scapula's and upper lateral thorax's musculocutaneous system.
• As a result, two primary arteries rather than one supplied the upper limb's axillary region in particular with arterial blood on both sides.
• These two arteries may be lingering branches of the capillary plexus of the growing limb buds because they came from the first portion of the axillary artery.
