  2. Tunica intima - Wikipedia

    en.wikipedia.org/wiki/Tunica_intima

    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. The endothelial cells are in direct contact with the blood flow.

    en.wikipedia.org/wiki/Tunica_(biology)

    Tunica muscularis refers to muscular layers in the walls of hollow organs such as the gut, where they are required for peristalsis, and sometimes for sphincters. [7] Tunica serosa is the serous membrane [7] Tunica vaginalis is the serous covering of the testis within the scrotum. [6] Tunica vasculosa could refer

  4. Vasa vasorum - Wikipedia

    en.wikipedia.org/wiki/Vasa_vasorum

    The structure of the vasa vasorum varies with the size, function and location of the vessels. Cells need to be within a few cell-widths of a capillary to stay alive. In the largest vessels, the vasa vasorum penetrates the outer (tunica adventitia) layer and middle (tunica media) layer almost to the inner (tunica intima) layer.

  5. Endothelium - Wikipedia

    en.wikipedia.org/wiki/Endothelium

    Endothelium lines the inner wall of vessels, shown here. Microscopic view showing endothelium (at top) inside the heart. The endothelium forms an interface between circulating blood or lymph in the lumen and the rest of the vessel wall. This forms a barrier between vessels and tissues and control the flow of substances and fluid into and out of ...

  6. Intima–media thickness - Wikipedia

    en.wikipedia.org/wiki/Intima–media_thickness

    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 .

  7. Wikipedia:Osmosis/Aortic Dissection - Wikipedia

    en.wikipedia.org/wiki/Wikipedia:Osmosis/Aortic...

    An aortic dissection is where part of the tunica intima (which is the endothelial, or the innermost layer of a blood vessel) of the aorta is ripped off. What happens is a tear in the tunica intima of the aorta forms, and the high-pressured blood flowing through the aorta begins to tunnel between the tunica intima and the tunica media ...

    North-eastern wall with well preserved niches. Shunet El Zebib is made of hardened mudbricks. It consists of two rectangular surrounding walls, interlaced like a shoe box. The outer wall measures 137 × 77 m and is c. 5 m thick and 12 m high. The inner wall (perimeter wall) measures 123 × 56 m and is c. 3 m thick and 8 m high.

  9. Tunica vaginalis - Wikipedia

    en.wikipedia.org/wiki/Tunica_vaginalis

    The visceral layer of tunica vaginalis of testis (lamina visceralis tunicae vaginalis testis) [4] is the portion of the tunica vaginalis that covers the testis and epididymis. It is the superficial-most of the three layers that constitute the capsule of the testis, with the tunica albuginea of testis situated deep to it.
