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.
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.
Tunica mucosa is the predominant Latin rendering of "mucous membrane" in English-speaking countries, though membrana mucosa also is acceptable and in some European languages is preferred. The name may be qualified in referring to particular regions of the body, such as tunica mucosa oris for the oral mucosa, and tunica mucosa uteri for the ...
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 ...
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.
The rugae can disappear with anterior vaginal wall prolapse which can occur when supports to the portion located between the vagina and bladder are damaged and the bladder bulges into the vaginal lumen. Vaginal self-examination includes visualizing the presence of vaginal rugae. [8] Anatomists identified rugae of the vagina as early as 1824. [9]

The tunica albuginea is a dense, [1] [2] blue-white [3] layer of fibrous tissue surrounding the testis. [ 1 ] [ 4 ] It is the middle of three envelopes forming the capsule of the testis; it is deep to the visceral layer of tunica vaginalis , and superficial to the tunica vasculosa testis (vascular layer of testis) .
