Basal Cell Skin Cancer Basal cell skin cancer is a cancer that develops from the skin’s basal cells. The basal cells are located in the outermost layer of the skin called the epidermis and can be found in the deepest layer of the epidermis [1]. Basal cells constantly divide to form new cells in order to replace the squamous cells. As basal cells move up in the epidermis‚ the basal cells flatten and eventually become simple squamous cells. Separating the epidermis from deeper layers of the skin‚ the

The Comparison and Contraction Between Various Skin Cells By: Michael McDaniel‚ Latoya Gates‚ Cristy Barfield‚ and Danielle Chapelle Abstract During this experiment we planned to compare and contrast human cheek cells of a variety of age groups‚ different stages of skin‚ and difference in species. We wanted to see if age could correlate to cell structure and size‚ if animal and human cells differed and if epidermal and cheek cells could differ in shape‚ size‚ and color. The age groups that

Mitosis /Meiosis Mitosis occurs all the time in all body cells. This occurs to produce new cells and replace old and dead cells. We produce new blood cells‚ bone cells‚ skin cells...the list can go on and on. Mitosis in a nutshell is the process of splitting the nucleus and it occurs hand in hand with the rest of the cell cycle and cytokenesis. Meiosis‚ on the other hand‚ is a process of taking a diploid cell (a cell with the full number of chromosomes) and producing haploid gametes

SKIN • Largest and heaviest organ of the body; accounts for about 15% of the total body weight • Also called as cutaneous membrane • Skin contains two layers‚ the epidermis and the dermis. • The hypodermis is the layer underneath the skin. FUNCTIONS • Skin is a protective covering that prevents harmful substances from entering the body. • It helps regulate body temperature and water loss. • It houses sensory receptors and contains immune system cells. • It synthesizes chemicals and excretes

SKIN I. INTRODUCTION Skin‚ outer body covering of an animal. The term skin is commonly used to describe the body covering of any animal but technically refers only to the body covering of vertebrates (animals that have a backbone). The skin has the same basic structure in all vertebrates‚ including fish‚ reptiles‚ birds‚ and humans and other mammals. This article focuses primarily on human skin. The skin is essential to a person’s survival. It forms a barrier that helps prevent harmful microorganisms

Layers of the skin The skin is an ever-changing organ that contains many specialized cells and structures. The skin functions as a protective barrier that interfaces with a sometimes-hostile environment. It is also very involved in maintaining the proper temperature for the body to function well. It gathers sensory information from the environment‚ and plays an active role in the immune system protecting us from disease. Understanding how the skin can function in these many ways starts with understanding

Many may believe the skin is the most obsolete organ that humans have‚ but that is far from the truth. Scientists‚ just recently‚ have come to the conclusion that human skin is equipped with the strongest‚ most convoluted defense system that the body can produce. To the naked eye‚ the surface of the skin may seem like a calm‚ untouched wasteland scattered with grass-like follicles‚ but‚ magnified‚ it is a battle zone of the body’s defenses fending off unwanted‚ invading bacteria (Metaphor).
