How long is a person s nail bed? What is the growth rate of the nails

A person's nail bed. and the growth rate of nails varies from person to person.

The nail bed refers to the piece of nail or toenail that covers the nail or toenail**, so you can see how long the pink part under the nail is.

The growth rate of nails varies not only from person to person, but also by age, climate, circadian cycle, menstruation, nutrition, gender, and other factors. Baby's nails grow about millimeters per week, and as they age, they grow faster and grow an average of 1 millimeter per week in adulthood, but most people slow down after the age of 30.

Nails grow fast in summer and slow in winter, fast in the morning and slow in the evening. In addition, regular rubbing also accelerates nail growth, so people who are used to using their right hand will have their right fingernails grow faster than those with their left hand. Not exactly the same rate of growth for every nail, usually the longer the finger, the faster the nail will grow.

First, borrow a diagram to illustrate where the nail bed is.

Second, know what a nail bed is.

You know, nails are derived from **. Like **, it is formed by the gradual differentiation of the mesenchyme of the embryonic body surface, ectoderm and lateral plate wall layer and somite raw dermal segment after 9 weeks of embryonic life.

The nail is divided into the nail plate, nail bed, nail fold, nail groove, nail root, nail epithelium, and subungual skin.

The nail bed is composed of an accessory layer equivalent to the epidermis, a basal layer, and a dermal reticular layer, which is directly integrated with the periosteum of the phalanges.

The half-moon mark is actually a part of the nail bed that grows to the bottom of the nail group, which is the "bed" that continues to grow nails, and the nutrients needed for nail growth belong to connective tissue.

It can be seen that the concept of nail bed is roughly divided into two parts, one is the tissue under the nail, and the other is the half-moon mark. So it depends on which piece you are asking about the growth period.

Finally, if you take the half-moon mark as an example, the growth cycle is different depending on how often you use the nails, which is about 3-5 months. It grows faster in summer and slower in winter. The more hands are used, the faster the nails will grow.

On average, the growth rate is about one inch (centimeters) per year.

Hello: The nail bed refers to the piece of nail or toenail cover**, so you see how long the pink part under the nail is, how long the nail bed is.

The growth rate of the nail varies from person to person, generally from the root of the nail to the front of the free edge, it takes about 100 days, and it can grow 3-4 cm in a year.

Hope mine is helpful to you, thanks.
