All of the following describe the cuticle EXCEPT:
It protects the matrix from infection
It overlaps the nail plate at the base
It is part of the nail plate itself
It can become too thick if not cared for
All of the following are functions of the nail matrix EXCEPT:
Produces new nail cells
Controls nail growth and thickness
Is visible as the nail plate
Contains nerves, lymph, and blood vessels
All of the following describe the nail bed EXCEPT:
It supports the nail plate
It supplies nutrients to the nail
It is made up of keratinized cells
It contains many nerves
All of the following describe the perionychium EXCEPT:
It surrounds the nail border
It protects against infection
It is part of the nail plate
It overlaps the nail edges
All of the following are true about the eponychium EXCEPT:
It protects the matrix from bacteria
It is often confused with the cuticle
It is living tissue at the base of the nail
It is nonliving tissue shed from the nail bed
All of the following describe the sidewall (lateral fold) EXCEPT:
It is the fold of skin on the sides of the nail
It protects the sides of the nail plate
It overlaps the nail bed directly
It can develop hangnails if damaged
All of the following describe the nail plate EXCEPT:
It is composed of 100 layers of keratin
It is the visible part of the nail
It contains blood vessels and nerves
It protects the fingertips
All of the following are characteristics of keratin in the nail EXCEPT:
It is a protein substance
It forms the structure of the nail plate
It is harder than skin keratin
It supplies moisture to the nail plate
All of the following are true about the 100 layers of keratin EXCEPT:
They make up the nail plate
They form compact, translucent layers
They are nourished directly by blood vessels
They protect the nail bed
All of the following describe the hyponychium EXCEPT:
It seals the free edge of the nail plate
It prevents pathogens from entering
It lies beneath the nail plate at the tip
It forms the nail groove
All of the following are true about nail growth EXCEPT:
Growth originates in the matrix
Growth rate slows with age
The toenails grow faster than fingernails
Growth is affected by health and nutrition
All of the following describe a healthy nail appearance EXCEPT:
Smooth surface
Uniform color
Deep ridges throughout
Slightly pink tone
All of the following describe specialized ligaments EXCEPT:
They attach the nail bed to the bone
They hold the nail matrix in place
They connect the nail groove to the free edge
They are tough fibrous tissue
All of the following are true about the proximal nail fold (PNF) EXCEPT:
It is folded skin over the matrix
It protects the emerging nail plate
It forms the eponychium at its edge
It attaches directly to the free edge
All of the following describe the nail groove EXCEPT:
It guides nail growth
It runs along the sides of the nail
It helps keep the nail plate in place
It is a visible part of the lunula
All of the following are true about the free edge EXCEPT:
It extends beyond the fingertip
It is the oldest part of the nail plate
It is attached to the nail bed
It can be filed and shaped
All of the following describe the importance of water in nails EXCEPT:
Nails contain about 15–25% water
Water content affects nail flexibility
Water content controls nail length
Dehydration makes nails brittle
All of the following are true about cuticle thickness EXCEPT:
Excessive thickness can cause hangnails
It varies from person to person
It determines nail plate growth speed
It can be managed with proper care
All of the following describe nail growth speed EXCEPT:
Fingernails grow faster than toenails
The middle finger nail grows fastest
Growth slows in cold weather
The thumb nail grows fastest
All of the following are true about the lunula EXCEPT:
It is the visible part of the matrix
It appears as a whitish, half-moon shape
It is found near the free edge of the nail
It is most visible on the thumb
All of the following are true about the bed epithelium EXCEPT:
It attaches the nail plate to the nail bed
It contains tiny grooves for adhesion
It produces the cuticle
It is part of the skin beneath the nail plate
All of the following are true about nail malformation EXCEPT:
It can be caused by injury
It may result from disease
It always means permanent damage
It can affect growth rate and shape
