Listed under are the 5 different type of cells found in the epidermis and their description:
1. Stem cells
These are what you call undifferentiated cells. These are cells found in the stratum basale, which is the deapest layer of the epidermis. These cells divide to create keratinocytes.
2. Keratinocytes
The make up the majority of the cells in the epidermis. They synthesize keratin which are proteins that make up your hair, skin, and nails. They can also be found in other organs inside your body.
3. Melanocytes
These cells can only be found in the stratum basale. They synthesize melanin with a brown to black pigment. These dark pigments serves as protection for the skin from harmful UV rays.
4.Merkel cells
Merkel cells are also known as <em>tactile cells</em>. They are the sensory receptor for touch. Merkel cells and the nerve fiber together are called the Merkel disc.
5. Dentritic cells
They are also known as <em>Langerhans cells</em>. They can be found in two layers of the epidermis: the stratum spinosm; and stratum granulosm. They are what you call macrophages that come from the bone marrow. They serve as immune cells that provide protection against toxins, microbes and other pathogens that try to penetrate the skin.

The clinical manifestations should the nurse expect are reports of leg fatigue, tortuous veins in the legs and pain in lower extremities when standing.
In addition, leg fatigue is a communal clinical manifestation triggered by venous stasis and insufficient tissue oxygenation. The vein walls deteriorate and dilate causing distended, bulging veins that look tortuous and darkened. As vein walls weaken and dilate venous pressure increases and the valves turn out to be useless in which vein stasis and inadequate oxygenation end result is limb discomfort. The discolored toenails effect from a fungus below the nail or chronic hypoxia, not varicose veins, confined to a small area of heat in a calf is a mark of thrombophlebitis and reddened zones on a leg are symptomatic of thrombophlebitis.
A letter indicates an articulating surface that is comprised of hyaline cartilage.
<h3>What is
hyaline cartilage?</h3>
- The synovial joints include hyaline cartilage, which facilitates joint motion.
- Chondrocytes and extracellular matrix make up its structure.
- The organization of the extracellular matrix, which determines the biomechanical characteristics of cartilage tissue, is greatly influenced by chondrocytes.
- Hyaline cartilage covers the ends of the bones where they come together to create a joint.
- In a typical healthy joint, this cartilage is bluish white and shiny.
- Its main job is to reduce friction and act as a little cushion between the ends of the bones.

Answer:
Convection drives the circulation of air in the earth’s atmosphere. The sun heats the air near the earth’s equator, which becomes less dense and rises upward. As it rises, it cools and becomes less dense than the air around it, spreading out and descending toward the equator again.
Explanation:
