救命啊!我的指甲!
从昨天开始,我的指甲就不太对劲!$郁闷$就是一般的手指甲和肉相连的那部分,轻轻拉一下,就和指甲分开来了,不疼,但是,指甲一下子就短了2mm左右,:mad::mad:

指甲的生长
指甲的生长靠甲根部的甲后皱避生发层。所以不必担心
Low magnification view of the root region of a developing nail from a fetal finger tip. Seen here is the nail fold (NF), nail bed (NB) and matrix (M) region of the nail root. The germinal cells (GC) are the basal layer of the epidermis that invaginates to form the matrix portion of the root. Beneath the nail bed is a portion f the distal phalanx showing an area of bone (B) in the diaphysis, and hyaline cartilage © in the epiphysis, along with an area of the epiphyseal plate (EpPl).
