The epidermis can be divided into two main parts which are the epidermis and the dermis. The epidermis is composed of layers of squamous (flattened) epithelial cells which provide us with protection from scrapes and friction and burns. It is also, for the most part, dead tissue. The dermis is the tissue underneath the epidermis and is largely connective tissue which contains our sensory receptors for feeling things like touch or heat as well as blood vessels which transmit heat to the skin so we can regulate our body temperature.
i believe nails continue to grow because even though your "Dead" as in your heart is not supplying oxygen to the brain, cells continue to do work for a short period of time, thus causing hair and nails to grow for a short ammount of time fingernails never grow after death...its your body's skin that shrink and it seems that the nails are growing...
The fastest growing part of the body is either the blood or hair or nails.
The correct sequence of increasing organizational complexity is cell, tissue, organ, organ system, and organism. Mammals have hair and nails, fish have bony scales, and birds have feathers.
sulfur is used in the process of protein synthesis, it is also a major part of connective tissue which is the tissue that helps keep organs together. Keratin also consists of sulfur which is the substance that is used to make your hair, nails, and skin.
From basal layer. This layer is called as stratum basale.
Nails are made up of layers/plates of keratinized epithelial cells.
because they grow from epithelial cells, are derivatives of epidermis, reside in dermis and are all over the body.
Parts composed of non living tissue, for example hair and nails.
The epidermis consists of stratified squamous epithelium. The dermis consists of fibrous connective tissue. The hypodermis consists of loose connective tissue and adipose tissue.
No. They are not connective tissue.
Your nails come from nail bed. Nails are connected to the skin below. The trauma to the nails is borne by large surface area. This gives very strong support to nails to withstand the applied force on the nails. Nails of some animals are very strong as a result.
nails
No, the fingernails are derived from epithelium. Nails are keratinized epidermal tissue.
Skin is an organ. It is the largest organ in the integumentary system, which is made up of skin, hair and nails. An organ is a collection of tissues that share a common function. Skin is made up of several layers of ectodermal tissue, and protects the inside of the body.
epidermis
Just use those huge staples.
