Endothelium

Japanese: endothelium

…The fourth layer is called Descemet's membrane, a thin but strong, structureless membrane on which the next layer of endothelial cells grows. The innermost layer is called the corneal endothelium, which consists of a single flat layer of endothelial cells. In humans, endothelial cells are thought to not divide after birth, and cell density gradually decreases with age. …

From [Epithelium]

…For example, the follicular epithelium of the thyroid gland is generally a simple cuboidal epithelium, but it can be a simple columnar epithelium or a simple squamous epithelium. The endothelium of blood vessels is generally a simple squamous epithelium, but is specifically called the endothelium. The epithelium lining the pericardial, peritoneal, and pleural cavities is generally a simple squamous epithelium, but is specifically called the mesothelium. Epithelia are divided into subtypes based on their function: glandular epithelium, absorptive epithelium, sensory epithelium, respiratory epithelium, etc. …

Japanese:

…第4層はデスメ膜Descemet’s membraneといい，薄いが強い無構造の膜で，次層の内皮細胞がこの内側に生える。最内層は角膜内皮endotheliumといい，扁平な1層の内皮細胞からなる。ヒトの場合，内皮細胞は生後，細胞分裂をしないと考えられ，年齢が加わるに伴い細胞密度は徐々に減少する。…

【上皮】より

…たとえば甲状腺の濾胞上皮は一般に単層立方上皮であるが，単層円柱上皮にも単層扁平上皮にもなりうる。　血管の内皮は一般に単層扁平上皮であるが，とくに内皮endotheliumとよび，また心膜腔，腹膜腔，胸膜腔の表面をおおう上皮は単層扁平上皮であるが，とくに中皮mesotheliumとよぶならわしである。　上皮はその機能によって，被蓋上皮，腺上皮，吸収上皮，感覚上皮，呼吸上皮などに分けられる。…
