立毛肌

毛囊皮脂腺导管开口至立毛肌附着处为峡部。

The portion of the follicle between the sebaceous duct and the insertion of the arrector pili muscle is the isthmus .

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。

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 .

立毛肌和皮脂腺上ER、PR、AR在两组间无显著性差异（P＞0.05）。

There was no significant difference of the ER , PR , and AR staining cells on arrector pill and sebaceous gland between the patients and controls .

DMD、BMD患者骨骼肌、皮肤立毛肌肌营养不良蛋白同时欠损

Dystrophin-Deficiency in skeletal muscle and in the dermatic arrector pili muscles of the patients with the DMD and 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。

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 ) .

立毛肌附着于皮脂腺之下的毛囊，当它收缩时，牵拉毛囊直立，产生鸡皮疙瘩。

The arrectores pilorum are attached to the hair follicles below the sebaceous glands and , in contracting , pull the hair follicle upward , producing gooseflesh .

这种感觉是由每个毛囊里的细小肌肉造成的，被称之为“立毛肌”，当这些肌肉收缩时，毛发就会立起来。

The sensation is caused by the tiny muscles underneath each follicle , called arrector pili , and when they contract , the hair is pulled upright .

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。

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 .
