触觉毛囊的结构模式基本上与被毛相似。触觉毛的毛囊被致密的纤维囊包围，纤维囊在毛囊的颈部周围形成一个组织环，即圆锥体。动脉和面神经的分支穿过囊的下部。动脉流入血窦。下窦或海绵窦被细胞小梁穿过;上窦或环窦包含“环壁”。“小梁和环壁是间充质鞘的附属物，间充质鞘是包裹卵泡的一层星状细胞。小梁中的星状细胞和海绵窦中的间质鞘吞噬血液中的碎屑。在环窦的顶端，间充质鞘被小静脉所充满，小静脉排出窦液。在海绵窦的间充质鞘和环窦的顶端发现了大量的肥大细胞。毛囊本身类似于任何粗糙的毛发，除了在下窦和上级窦之间的边界处的外鞘变得极大地扩张成所谓的上级扩大。玻璃膜在上级增大的下部也变得很厚。毛乳头，不像被毛是丰富的血管，偶尔形成一个球内血窦。毛乳头和间充质鞘异染染色。外鞘含有糖原，直到上级膨大的中部。
The structural pattern of tactile hair follicles is essentially similar to that of coat hairs. Follicles of tactile hairs are surrounded by a dense fibrous capsule, which forms a ring of tissue, the conical body, around the neck of the follicle. Arteries and a branch of the facial nerve penetrate the lower portion of the capsule. The arteries empty into the blood sinus. The lower, or cavernous sinus is traversed by cellular trabeculae; the upper, or ring sinus contains the "ringwulst." The trabeculae and the ringwulst are appendages of the mesenchymal sheath, a layer of stellate cells which envelops the follicle. Stellate cells in the trabeculae and mesenchymal sheath in the cavernous sinus phagocytose detritus from the blood. At the apex of the ring sinus the mesenchymal sheath is riddled by venules which drain the sinus. Numerous mast cells are found in the mesenchymal sheath in the cavernous sinus and in the apex of the ring sinus. The hair follicle itself resembles that of any coarse hair with the exception that the external sheath, at the boundary between the inferior and superior sinus becomes tremendously dilated into the so-called superior enlargement. The glassy membrane also becomes very thick in the lower portion of the superior enlargement. The dermal papilla, unlike that of coat hairs is richly vascular and occasionally forms an intrabulbar blood sinus. The dermal papilla and the mesenchymal sheath stain metachromatically. The external sheath contains glycogen up to the middle of the superior enlargement.
