The tunica media is made up of smooth muscle cells, elastic tissue and collagen.It lies between the tunica intima on the inside and the tunica externa on the outside.. The middle coat (tunica media) is distinguished from the inner (tunica intima) by its color and by the transverse arrangement of its fibers.
Mönckeberg medial arteriosclerosis, also known as medial arterial calcinosis, is a condition where the tunica media layer of blood vessels calcifies, visible on plain radiography or sectional tomography, and can sometimes be detected in dental panoramic radiographs.
A tear in vasa vasorum situated in tunica media layer of aorta may start pathologic cascade of events leading to aortic dissection. [4] Presence of corkscrew collateral vessels in vasa vasorum is a hallmark of Buerger's disease and distinguishes it from Raynaud's phenomenon. [11]
The tunica externa (Neo-Latin "outer coat"), also known as the tunica adventitia (Neo-Latin "additional coat"), [1] [2] is the outermost tunica (layer) of a blood vessel, surrounding the tunica media. It is mainly composed of collagen and, in arteries, is supported by external elastic lamina. The collagen serves to anchor the blood vessel to ...
Intima–media thickness (IMT), also called intimal medial thickness, is a measurement of the thickness of tunica intima and tunica media, the innermost two layers of the wall of an artery. The measurement is usually made by external ultrasound and occasionally by internal, invasive ultrasound catheters .
The tunica intima (Neo-Latin "inner coat"), or intima for short, is the innermost tunica (layer) of an artery or vein. It is made up of one layer of endothelial cells (and macrophages in areas of disturbed blood flow), [ 1 ] [ 2 ] and is supported by an internal elastic lamina .
Micrograph showing the internal elastic lamina (thin pink wavy line - image edge mid-left to image edge bottom-centre-left). H&E stain.. The internal elastic lamina or internal elastic lamella is a layer of elastic tissue that forms the outermost part of the tunica intima of blood vessels.
Tunica albuginea (disambiguation), three different layers of connective tissue; Tunica vasculosa (disambiguation), two different vascular layers; Tunica externa, outermost tunica (layer) of a blood vessel, surrounding the tunica media; Tunica intima, for short, is the innermost tunica (layer) of an artery or vein
