The greatest concentration of sensory nerves in the muzzle and facial disc of mammals is in the nose. In most nocturnal mammals, these nerves penetrate the epidermis of the naked nose either or in bundles which resemble the corpuscles of Eimer. The hair follicles around the nose, lips, and eyes, as well as the heaviply innervated vibrissae follicles found in all hairy mammals except man, are well innervated; those elsewhaere are not. Everywhere on the human body both large and small follicles abound in sensory nerves. These morphologic observations suggest that in most mammals the most sensitivie areas of the skin are at the anterior and posterior ends (not reported here), and that human skin is better equipped for cutaneous sensibility than that of any other mammal.
哺乳动物口鼻部和面部盘状区域中感觉神经最密集的部位是鼻子。在大多数夜行性哺乳动物中，这些神经以单个或成束的形式穿透裸露鼻子的表皮，这些束状结构类似于艾美尔小体。鼻子、嘴唇和眼睛周围的毛囊，以及除人类外所有有毛哺乳动物中神经高度密集的触须毛囊，都有丰富的神经支配；而身体其他部位的毛囊则没有。人体各处无论大小毛囊都有丰富的感觉神经。这些形态学观察结果表明，在大多数哺乳动物中，皮肤最敏感的区域位于前端和后端（此处未报告），并且人类皮肤在皮肤敏感性方面比其他任何哺乳动物都更具优势。
