nail matrix การใช้

• The nail plate is generated by the nail matrix located just under the cuticle.
• It is believed that there is a temporary cessation of cell division in the nail matrix.
• In worst cases, if the infection causes injury or damage to the nail matrix, deformity in the nail may become permanent.
• Often the toenails will have to be removed and chemical therapy or laser therapy used to kill the nail matrix at the base of the nail where all nail growth takes place.
• Because pitting is caused by defective layering of the superficial nail plate by the proximal nail matrix, any localized dermatitis ( e . g ., atopic dermatitis or chemical dermatitis ) that disrupts orderly growth in that area also can cause pitting.
• As the nail grows, the area closest to becoming exposed to the outside world ( distal ) produces the deeper layers of the nail plate, while the part of the nail matrix deeper inside the finger ( proximal ) makes the superficial layers.
• Protein is a building material for new nails; therefore, low dietary protein intake may cause anemia and the resultant reduced hemoglobin in the blood filling the capillaries of the nail bed reflects varying amounts of light incident on the nail matrix resulting in lighter shades of pink ultimately resulting in white nail beds when the hemoglobin is very low.
