Large, elastic arteries are composed of cells and a specialized extracellular matrix that provides reversible elasticity and strength. Elastin is the matrix protein responsible for this reversible elasticity that reduces the workload on the heart and dampens pulsatile flow in distal arteries.

The elastic arteries are large arteries close to the heart such as the aorta and the carotid arteries and are abundant in elastin. Their media is made of concentric layers whose unit is called a lamellar unit [ 1 ], a pair of elastic lamina mainly made of elastin and a smooth muscle-rich layer (Fig. 4.1 ).
1 Ιαν 2008 · This novel pseudo-SEF models not only arterial mechanics at maximal VSM contraction but also the myogenic contraction of the VSM in response to local increases in stretch.
18 Σεπ 2019 · Schematic drawing of a healthy elastic artery. Stress-free (B 0 ), unloaded (B * ) and deformed (B) configuration of an arterial segment. The coordinate triplets (ρ, φ, ξ), (R, Θ, L) and (r, θ,...
1 Σεπ 2015 · Elastic arteries have a relativ ely large diameter and ar e closer to the heart (e.g., aorta or carotid artery); their media contains a lot of elastic membranes. The number of elastic...
1 Φεβ 2002 · When measuring PWV to determine arterial elasticity, information about the shape of the pulse wave is, perforce, discarded. If this is not done the ‘true’ wave velocity cannot be derived, and false values of elasticity will result.
Elastic arteries include the largest arteries in the body, those closest to the heart, and give rise to the smaller muscular arteries. The pulmonary arteries, the aorta, and its branches together comprise the body’s system of elastic arteries.
