Sun exposure causes melanocytes to increase production of melanin in order to protect the skin from damaging ultraviolet rays, producing a suntan. Melanocytes produce the skin coloring or pigment known as melanin, which gives skin its tan or brown color and helps protect the deeper layers of the skin from the harmful effects of the sun. The basal cell layer contains cells called melanocytes. The basal cell layer is also known as the stratum germinativum due to the fact that it is constantly germinating (producing) new cells. The basal cells continually divide, and new cells constantly push older ones up toward the surface of the skin, where they are eventually shed. The basal layer is the innermost layer of the epidermis, and contains small round cells called basal cells. The epidermis layer itself is made up of five sublayers that work together to continually rebuild the surface of the skin: The Basal Cell Layer The epidermis contains the melanocytes (the cells in which melanoma develops), the Langerhans' cells ( involved in the immune system in the skin), Merkel cells and sensory nerves. 05 mm thick on the eyelids, and is 1.5 mm thick on the palms and the soles of the feet. The thickness of the epidermis varies in different types of skin it is only. The epidermis is the outermost layer of the skin, and protects the body from the environment. Also, licensure helps educators prepare students for their future in engineering.Acknowledgements Layers of the Skin The Epidermis
Exemptions to state laws are under attack, and in the future, those in education, as well as industry and government, may need to be licensed to practice. Many states require that individuals teaching engineering must also be licensed.

In many federal, state, and municipal agencies, certain governmental engineering positions, particularly those considered higher level and responsible positions, must be filled by licensed professional engineers. Licensure for engineers in government has become increasingly significant. Licensure for a consulting engineer or a private practitioner is not something that is merely desirable it is a legal requirement for those who are in responsible charge of work, be they principals or employees. PEs shoulder the responsibility for not only their work, but also for the lives affected by that work and must hold themselves to high ethical standards of practice. Only a licensed engineer may prepare, sign and seal, and submit engineering plans and drawings to a public authority for approval, or seal engineering work for public and private clients. PEs must also continuously demonstrate their competency and maintain and improve their skills by fulfilling continuing education requirements depending on the state in which they are licensed. What makes a PE different from an engineer? Pass the Principles and Practice of Engineering (PE) exam
Pass the Fundamentals of Engineering (FE) examĬomplete four years of progressive engineering experience under a PE
To use the PE seal, engineers must complete several steps to ensure their competency.Įarn a four-year degree in engineering from an accredited engineering program Now every state regulates the practice of engineering to ensure public safety by granting only Professional Engineers (PEs) the authority to sign and seal engineering plans and offer their services to the public. In order to protect the public health, safety, and welfare, the first engineering licensure law was enacted in 1907 in Wyoming. By combining their specialized skills with their high standards for ethics and quality assurance, PEs help make us healthier, keep us safer and allow all of us to live better lives than ever before.Ī century ago, anyone could work as an engineer without proof of competency. Yet the results are well worth the effort. Then, to retain their licenses, PEs must continually maintain and improve their skills throughout their careers.

To become licensed, engineers must complete a four-year college degree, work under a Professional Engineer for at least four years, pass two intensive competency exams and earn a license from their state's licensure board.
To yourself, it's a symbol of pride and measure of your own hard-won achievement. Among your colleagues, it demands respect. To an employer, it signals your ability to take on a higher level of responsibility. To a client, it means you've got the credentials to earn their trust.
