Study Notes
- Sudoriferous Gland is a small tubular structure of the skin which produces sweat.
Function of Nail Parts
- Nail Plate: Visible part of the nail that goes from the lunula to the free edge.
- Nail Bed: Holds living tissue and contains capillaries and glands.
- Hyponychium: Is skin under the free edge, beyond the distal end.
- Nail Root/Matrix: Consists of special cells and makes new nails.
- Nail Folds: Tissue that encloses the matrix and attaches nails to the skin.
- Cuticle: Non-living tissue attached to the nail plate
- Free Edge: Extends past the finger or toe.
- Lunula: Crescent shape at bed of nail.
Nail Plate Growth
- Nail Plate Growth originates from active tissue.
- The active tissue is known as the matrix and located in the mantle.
Influence of Nail Growth
- Health: Poor circulation and lack of general well-being can slow nail growth.
- Trauma: To the nail bed can result in visible changes in the nail plate or affect nail growth.
- Medications: Antibiotics can cause nails to lift away from the skin.
- Diet: Lack of nutrients in the body due to poor diet.
- Infection: Skin infection can cause yeast or bacteria to grow and lift the nail plate or damage nails as they grow.
- Muscles and bones of the lower arm and hand.
