毛孔与毛囊
由于毛孔和毛囊单词通常被互换使用,以定义皮肤中最近引起痤疮病变的微小开口,因此,如果有的话,我们让我们找出毛孔和毛囊之间的差异。
什么是毛孔?
毛孔是皮肤中的微小开口,除了手掌和鞋底,它们都在体内发现。毛孔的医学术语是毛囊。每个孔都连接到皮脂腺腺生产皮脂的地方。皮肤中有两种类型的毛孔,即正常毛孔和粉刺- 毛孔。正常孔衬有称为角质形成细胞的专门细胞。与正常毛孔相反,容易痤疮的毛孔衬有异常粘的死角质形成细胞。
什么是毛囊?
毛囊在皮肤表面下方。每个头发都有自己的卵泡,由角质形成细胞衬里。角质形成细胞的寿命短。一旦死亡的角质形成细胞脱落,它们将被新的健康角质形成细胞所取代。每个毛囊都附着在称为皮脂腺的专门生产腺体。这些腺体产生一种称为皮脂的油。皮脂沿着头发的轴流,并通过卵泡的开口来到外面。当它流失时,它将死细胞从毛囊中移出。主要是遗传因素决定皮脂腺的大小。另外,皮脂腺产生的皮脂量通常取决于激素因子。 For example, during the puberty (which is caused by certain hormonal activities) sebaceous glands produce more sebum than ever before. Because of that more dead cells come out the follicle with sebum and they stick together to form a plug that block the opening of the pore. These pores lately develop as pimples. Usually in women, the follicles located in face, back and chest are filled with very tiny, light hairs called vellus hairs, which are invisible to the naked eye. However, in men, these areas are filled with dark, thick hairs known as terminal hairs.
