formulation is much like the process of growth in the epidermal layer of the skin. 2.Epidermis-Is composed of the stratified squamous epithelium. This type of epithelial tissue consists of flat scale-like cells arranged in overlapping layers or strata. The epidermis does not have a blood supply or any connective tissue so it is dependent for nourishment on the deeper layer of skin. 3.Dermis- Is the middle layer of skin‚ located between the epidermis and the subcutaneous layer.

bundles are present in vascular tissue system and are distributed in the stele. The stele is the central column of Dicol stems. Each vascular bundle may be made up of both xylem tissue and phloem tissue with a cambium as in dicot stems or without cambium as in Monocot stems or of one kind of tissue xylem or phloem as in roots. Vascular bundle may be regularly arranged in a ring as in the stems of most dicotyledons and in all roots or they may be scattered in the ground tissue as in stems of Monocotyledons

There are thousands of burn victims awaiting donations of human tissue to help meet critical needs in reconstructive surgery. My current case #49 regards the selling of human tissue donations. It’s a complicated situation where a few medical centers have acquired a partnership with a biotechnological company called Ardias Corporation. Ardias wants to create a tissue bank to help facilitate researchers with disease-specific tissue that will provide a link to accurate genetic sequence with diseases

1. Discuss 4 major types of cells that can be found in the skin. The 4 major types of cells that are found in the human body are keratinocytes‚ melanocytes‚ epidermal dendritic (Langerhans)‚ and the tactile (Merkel) cells. The keratinocytes‚ which are epithelia cells‚ are the most abundant cells in human body and dominate the epidermis. These cells contain keratin and work together to form layers known as thick skin‚ which consists of 5 layers‚ and thin skin‚ which consists of 4 layers. These cells

gravel and was brought to the ER by paramedics. On examination‚ his right femur appeared to be fractured. X-ray studies confirmed an oblique‚ compound fracture which fortunately did not injure the femoral artery. However‚ there is a possibility of soft tissue damage in the area of the fracture. After routine blood work results showed that Mr. Michaels could tolerate surgery‚ he was taken to surgery for an open reduction. The fracture was secured with a plate and screws. A myorrhaphy was also necessary

Cells of the body are organized into four fundamental tissues; epithelial‚ connective‚ muscle and nerve. Epithelial tissues line all surfaces of the body: the skin‚ cavities‚ ducts‚ vessels. They are named according to the cell shape on the free surface. Cells of a tissue are held together by the basement membrane and intercellular fibbers. These tissues receive their nutrition by diffusion‚ for they are without blood vessels. Simple squamous epithelium lines all blood and lymphatic vessel‚ including
