内根鞘

毛囊内根鞘细胞含ACP。

The cells of internal root sheath contained ACP .

毛乳头显示为模糊发暗无固定形状，内根鞘、外根鞘、毛干发黑毛乳头不可见，即为非生长期毛囊。

Non-growing period hair follicles shown blur and non-immobility construction without hair shaft , inner root sheath and outer root sheath .

毛干和内根鞘当到达体表时融合在一起：外根鞘仍然保持在原来的位置。

The hair shaft and inner root sheath move together as the hair grows toward the surface : the outer root sheath remains fixed in position .

内根鞘、外根鞘界限模糊，结缔组织性鞘细胞纤维排列杂乱，结缔组织细胞减少。

The bourn of internal root sheath and external root sheath was blurry , the fiber of connective tissue sheath cell arrayed disordered , the number of connective tissue cell reduced .

毛球之上的细胞形成毛发，产生由分化的表皮细胞构成的同心环状区，形成内根鞘和外根鞘。

The hair is formed from cells just above the bulb , which also give rise to concentric zones of differentiated epithelial cells destined to form the inner and outer root sheaths .

【结果】绒山羊的毛囊结构同其它动物一样，由毛球、连接组织鞘、外根鞘、内根鞘和毛干几部分组成。

【 Result 】 The hair follicle structure of cashmere goat was in the same manner compared with other animals , which was composed of hair bulb , connective tissue sheath , outer root sheath , inner root sheath and hair shaft .

表皮和它的附属器（毛囊和相关腺体）构成了机体的外部屏障，而毛囊是皮肤重要而复杂的附属器，从内向外依次为毛干、内根鞘、外根鞘组成。

The epidermis and its appendages ( hair follicles and associated glands ) make up the external barrier of the body . Hair follicle is an important and complex epidermal appendage of skin , composed of hair shaft , inner root sheath and outer root sheath .
