Along one side of the follicle, two buds are formed: an upper, which develops into the sebaceous gland, and a lower, which becomes the attachment for the arrector pili muscle. 毛囊的一侧形成两个胚芽:上部胚芽生长进入皮脂腺,下部胚芽形成立毛肌的附着处。
The portion of the follicle between the sebaceous duct and the insertion of the arrector pili muscle is the isthmus. 毛囊皮脂腺导管开口至立毛肌附着处为峡部。
When our ancestors were covered in fur, muscles in their skin called "arrector pili" contracted when they were upset or cold, making their fur stand on end. 我们的祖先身上覆有毛发,当他们感到紧张或寒冷时,皮肤上的肌肉“立毛肌”就会收缩,使毛发竖立起来。
Objective To study and contrast the expression of Dystrophin in skeletal muscle and in Arrector pili muscle of the patients with Duchenne muscular dystrophy ( DMD) and Becker muscular dystrophy ( BMD). 目的研究、对比肌营养不良蛋白(dystrophin)在杜兴型肌营养不良(duchennemusculardystrophy,DMD)和贝克型肌营养不良(Beckermusculardystrophy,BMD)患者活检骨骼肌、皮肤立毛肌中的表达。
Dystrophin-Deficiency in skeletal muscle and in the dermatic arrector pili muscles of the patients with the DMD and BMD DMD、BMD患者骨骼肌、皮肤立毛肌肌营养不良蛋白同时欠损
Recently people confirmed that a repository of progenitor cell was exist in the bulge region, specialized portion in the outer root sheath of upper hair follicle, which is located below the opening of the sebaceous duct and serves as the insertion site of arrector pili muscle. 隆突区是毛囊上段外根鞘向外隆起的部分,位于皮脂腺导管开口的下方,是立毛肌的附着处。
