The brachial artery is the major blood vessel of the (upper) arm. It is the continuation of the axillary artery beyond the lower margin of teres major muscle.It continues down the ventral surface of the arm until it reaches the cubital fossa at the elbow.
Arterial lines are most commonly used in intensive care medicine and anesthesia to monitor blood pressure directly and in real-time (rather than by intermittent and indirect measurement) and to obtain samples for arterial blood gas analysis.
Collateral circulation is the alternate circulation around a blocked artery or vein via another path, such as nearby minor vessels. [1] It may occur via preexisting vascular redundancy (analogous to engineered redundancy), as in the circle of Willis in the brain, or it may occur via new branches formed between adjacent blood vessels (neovascularization), as in the eye after a retinal embolism ...
Arteries of head and neck. Angiogram of the arterial supply.. The cerebral arteries describe three main pairs of arteries and their branches, which perfuse the cerebrum of the brain.
The upper five or six anterior intercostal arteries are branches of the internal thoracic artery (anterior intercostal branches of internal thoracic artery).The internal thoracic artery then divides into its two terminal branches, one of which - the musculophrenic artery - proceeds to issue anterior intercostal arteries to the remaining 6th, 7th, and 9th intercostal spaces; these diminish in ...
An arteriole is a small-diameter blood vessel in the microcirculation that extends and branches out from an artery and leads to capillaries. [1]Arterioles have muscular walls (usually only one to two layers of smooth muscle cells) and are the primary site of vascular resistance.
