Nail plate: The nail plate is mainly produced by the matrix which emerges via the proximal nail fold and is held in place by the lateral nail folds. It overlays the nail bed and detaches from the latter at the hyponychium which is the skin under the free edge of the plate. The nail plate has an average thickness of 0.25–0.6 mm. It is hard, yet slightly elastic, translucent, convex and is made up of approximately 25 layers of dead

Within this essay I will be explaining the functions of different types of proteins within living organisms, and discussing what their purposes are. The importance of this is to recognise different types of proteins within cells and get an understanding of what is happening within our bodies. I will also conduct a conclusion which will summarise the main points have researched within this essay. Proteins are tiny molecules which are made of amino acids. They are joined together to form living tissues

Avian Keratin Disorder The popular article that I read was Long, curved, akimbo: Hope uncovered for bird beak deformity by Dan Joling. Joling touched base on an issue involving birds in Alaska. The black-capped chickadee has been found with abnormally long beaks. Joling states that “Some beaks looked like sprung scissors, unable to come together at the tips. Others curved up or down like crossed sickles” (Joling). This beak deformity is known as Avian Keratin Disorder (AKD), and as the name suggests

ESC Biomarkers and their role in wound healing Wound healing involves a complex orchestration of processes that suppress infection and restore the dermal barrier. Healing begins immediately following the laceration to the epidermis with hemostasis, which includes initial vasoconstriction and thrombocyte clumping. Following is an influx of fibroblasts (which help clot the wound opening), and inflammatory macrophages. Next, granulation tissue creates a framework for forming permanent connective tissue

The lower part of the hair shaft is the papilla, it is covered with a lot of dermal papillae, which is made up of many blood vessels as well as other compounds to feed the hair. Around the hair, the root is

epidermises deliver keratin and the protein allows the epidermis to become a muscular protective coating for the skin.   o Stratum basale- These cells are the deepest coating of the epidermis because it is near the dermis. The cells are also attached to the dermis. o Stratum spinosum and stratum granulosum - Both layers are filled with keratin. When the cells leave the granulosum, they drop off and make a way for the stratum lucidum. However, the spinosum is composed of pre-keratin, and the granulosum
