Ectoderm
Skin, hair, nails, and the lining of organs such as the respiratory tract, gastrointestinal tract, and urinary tract are of epithelial origin. Epithelial cells serve as a protective barrier and have various functions depending on their location in the body.
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.
No, it is a protein found in tissue to reduce friction
the slang term for this is "boobies" but that is not a medical term.
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...
From basal layer. This layer is called as stratum basale.
Nails are made up of layers/plates of keratinized epithelial cells.
Hair, nails, and cutaneous glands are considered epithelial tissue because they originate from the epidermis, which is a type of epithelial tissue. Epithelial tissues function to protect, absorb, and secrete, which aligns with the roles of hair, nails, and cutaneous glands in protecting the skin, providing sensory perception, and regulating body temperature.
Both hair and nails develop from the specialized keratinized cells called epithelial cells. These cells are found in the skin and are responsible for producing keratin, the protein that gives hair and nails their structure and strength.
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.
Parts composed of non living tissue, for example hair and nails.

The embryo layer that forms the skin and nervous tissue is the ectoderm. It gives rise to the epidermis of the skin, hair, nails, and the nervous system including the brain and spinal cord. The ectoderm is one of the three primary germ layers that develop during gastrulation in embryogenesis.
The thickened epithelial tissue at the proximal end of the nail body is called the cuticle or eponychium. It acts as a barrier to protect the nail matrix, the area where nail growth occurs, from external factors and infection. The cuticle also helps to maintain the health and integrity of the 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.
