It is called the enamel. It's the most external layer of a tooth and the hardest substance in the body.
Enamel is called the dentine part of the tooth
Epidermis of skin, and its derivatives Epithelial lining of the mouth and rectum Cornea and lens of eyes The nervous system, and renal medulla, tooth enamel, epithelium of the pineal and pituitary glands

yes
Organs that originate from ectoderm include the skin, hair, nails, brain and nervous system, as well as the lens of the eye and enamel of teeth.
Calcium is a metal element present in tooth enamel.
The three germ layers of a gastrula are the ectoderm (outer layer), mesoderm (middle layer), and endoderm (inner layer). These layers give rise to different tissues and organs in the developing embryo through a process known as gastrulation.
That is correct. In case of the embryo, you have three layers, in initial period. The cells from the ectoderm enter the mesoderm to form the neural tube. So the neural tube is formed by invagination of the ectoderm in the mesoderm. Your nervous system is developed from this neural tube.In vertebrates, ectoderm gives rise to hair, skin, nails or hooves, the lens of the eye, the epithelia (surface, or lining, tissues) of sense organs, the nasal cavity, the sinuses, the mouth (including tooth enamel), the anal canal and nervous tissue, including the pituitary body.
Eroding away of tooth enamel
it is called enamel. so the answer is true It is called enamel
Tooth enamel, calcium. Nail enamel, Biotin.
