What is the second epithelial tissue at the proximal end of the nail body called?
The proximal end of the nail near the root forms a whitish crescent shape known as the lunula where a small amount of nail matrix is visible through the nail body. Around the proximal and lateral edges of the nail is the eponychium, a layer of epithelium that overlaps and covers the edge of the nail body.
What type of connective tissue is reticular layer?
