Tunica media. Transverse section through a small artery and vein of the mucous membrane of the epiglottis of a child. (Tunica media is at 'm') The tunica media ( New Latin middle coat), or media for short, is the middle tunica (layer) of an artery or vein. It lies between the tunica intima on the inside and the tunica externa on the outside The tunica media is the middle layer. It is surrounded on top by the tunica adventitia or tunica externa, and underneath by the tunica intima. This middle layer contains soft elastic tissues and, in the largest of the arteries, it houses nerves. It is usually the thickest of the layers, and is the most flexible, making it an essential component. The tunica media, or middle coat, is made up principally of smooth (involuntary) muscle cells and elastic fibres arranged in roughly spiral layers. The outermost coat, or tunica adventitia, is a tough layer consisting mainly of collagen fibres that act as a supportive element

The middle coat (tunica media) is distinguished from the inner by its color and by the transverse arrangement of its fibers. In the smaller arteries it consists principally of plain muscle fibers in fine bundles, arranged in lamellæ and disposed circularly around the vessel. These lamellæ vary in number according to the size of the vessel.

The tunica media is the thickest tunic; it is predominantly muscular in arterioles and most arteries, and it is predominantly elastic in the largest arteries (the so-called elastic arteries such as the aorta and the common carotid). The tunica adventitia is relatively thin tunica media: almost entirely smooth muscle in six or less concentric layers tunica adventitia: almost as thick as t. media; no external elastic lamina small arterioles: tunica intima: same tunica media: two or one concentric layers of smooth muscle tunica adventitia: merges imperceptibly with surrounding c

The tunica media is composed chiefly of circumferentially arranged smooth muscle cells. Again, the external elastic lamina often separates the tunica media from the tunica adventitia. Finally, the tunica adventitia is primarily composed of loose connective tissue made up of fibroblasts and associated collagen fibers Tunica Media: Outside of the IEL lies the tunica media which is composed of a fairly thick layer of vascular smooth muscle cells, which is itself surrounded by a second, thin sheet of elastic tissue known as the External Elastic Lamina; Tunica Adventitia: Is a fairly wide collagenous layer in muscular arteries with interspersed bundles of elasti Components of the tunica media: Primarily elastic fibers. Primarily smooth muscle. Function: Absorb energy of left ventricular contraction of the heart during systole → dampen pulsatile blood flow to reduce the difference in blood pressure between systole and diastol

Vein. Vein valve. Small to medium-sized veins are characterised by the presence of valves In particular, the tunica media contains smooth muscle cells (allowing for vasoconstriction), and in the larger vessels, a significant amount of elastin (allowing these vessels to stretch and recoil in response to changes in pressure during systole and diastole).

Tunica adventitia - is the outermost layer which is largely consists of collagen fibres. Arteries and Arteriole The middle layer, known as the tunica media, contains smooth muscle fibers and elastic fibers that change the diameter of the vein, notes Pearson Education. The middle layer is the thickest of the three main layers. The tunica initima, or inner layer, is made of specialized cells of the endothelium, which lines the veins and the interior of.

Tunica media . This consists of concentric layers of smooth muscle fibres and elastin. Some small blood vessels lack muscle fibres and elastin. Tunica intima . This is the innermost coat. In blood vessels the simple squamous lining cells (epithelium) is called the endothelium the media (or tunica media) sandwiched between the intima and adventitia, and the thickest layer; provides structural support, vasoreactivity and elasticity; composed of smooth muscle cells, elastic fibers and connective tissue, which vary in amount depending on the type of vessel The tunica media is the thickest tunic; it is predominantly muscular in arterioles and most arteries, and it is predominantly elastic in the largest arteries (the so-called elastic arteries such as the aorta and the common carotid).
