Yes, nails are one of the accessory structures of your skin.
Yes, screws can be used for framing structures, but they are typically not as strong as nails for this purpose. Screws are often used in conjunction with nails or other fasteners to provide additional support and stability in framing projects.
Keratins dead tissue, so finger nails, toe nails, horse hooves, horns etc.
Box nails are thinner and have a smaller head compared to common nails. They are commonly used for lighter woodworking projects and finishing work. Common nails are thicker and have a larger head, making them suitable for heavier construction tasks like framing and building structures.
True. Both nails and hair are made of a protein called keratin, and the DNA within the cells that produce these structures is the same. Thus, the DNA from your nails is the same as the DNA from your hair.
No, it is not true that melanin is the most abundant protein in dead epidermal structures like hair and nails. The primary protein present in these structures is keratin, which provides strength and resilience. Melanin, on the other hand, is a pigment responsible for color and is found in the living cells of the skin, hair, and eyes, but not in significant amounts in the dead structures themselves.
Epidermal derivatives are structures that develop from the epidermal layer of the skin. Examples include hair, nails, and glands (such as sweat glands and oil glands). These structures serve various functions, such as protection, thermoregulation, and sensory perception.
Areas with high winds put more stress on structures, causing nails to be subjected to greater force. Nails with stronger holding power are needed to ensure that structures remain secure and do not become loose or damaged due to the strong winds. This helps to maintain the overall stability and safety of the building.
During embryonic development, nails begin to form around the 10th week of gestation. Initially, they appear as small, nail-shaped structures at the tips of fingers and toes, developing from the nail matrix. As the embryo continues to grow, the nails harden and elongate, becoming more defined. This process is part of the overall development of the integumentary system, which includes skin, hair, and nails.

That's great! Roland's precision and strength will make him a valuable asset for any construction project. His ability to hammer nails accurately and with force will ensure the stability and durability of the structures he works on.
They are all made of keratin.
