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

Undertake tissue viabillity risk assessments. 1.1 Describe the anatomy and physiology of healthy skin. Skin is the largest organ of the body‚ covering and protecting the entire surface of the body. The total surface area of skin is around 3000 sq inches or roughly around 19‚355 sq cm depending on age‚ height‚ and body size. The skin‚ along with its derivatives‚ nails‚ hair‚ sweat glands‚ and sebaceous glands forms the integumentary system. Besides providing protection to the body the skin has

Epithelial Tissue covers body surfaces (epi‚ on + thelium‚ surface). Epithelial tissue consists of cells attached to one another to form an uninterrupted layer of cells that separates the underlying tissues from the outside world. The body’s epithelium not only covers its obvious surfaces (such as the epidermis of the skin and the linings of respiratory‚ urinary‚ and digestive tracts) but also extends into all of the complex invaginations which form lungs‚ kidneys‚ sweat glands‚ digestive glands

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

Chapter 6 Ossecous Tissue and Skeletal Structure The Skeletal system consists of bones and their associated connective tissues‚ including cartilage‚ tendon and ligaments. I. Function of the Skeletal System 1) Bone- The most rigid component of skeletal system a) Support- serves as a framework; Maintains body’s shape b) Protection- of critical internal organs‚ brain‚ heart and lungs c) Lever System- for muscles to produce body movements d) Mineral storage- e.g. Calcium and

September‚ 2013 Tissue Ownership “I think people are morally obligated to allow their bits and pieces to be used to advance knowledge to help others” (Korn). Different people have opposing opinions on the topic of whether or not patients or doctors own the body tissues after it’s been removed from the patient. Ownership is the act‚ state‚ or right of possessing something. Tissue ownership is different from ownership because once it leaves your body‚ you no longer own it. Contributing your tissues to the

Minerals help regulate the body process and body structure. There are two types of minerals‚ major and minor‚ a major mineral is necessary for many processes in your body‚ especially fluid balance‚ maintenance of bones and teeth‚ muscle contractions and nervous system function. Calcium and potassium are just a couple of the minerals in this group which contributes to the body’s everyday functions. Calcium aids the body with bone mass and bone density that helps support body weight allowing us to run

CALLUS INDUCTION By: Sonali Pradhan‚08-11-2013 ABSTRACT The present study describes a reliable method for callus induction of Hybanthus ennaspermus‚an important medicinal plant plant. Calli were in vitro initiated from leaves segments using Murashige and Skog (1962) basal media. The effect of NAA (_-naphthalene acetic acid) and 2‚4-D (2‚4-Dichlorophenoxy acetic acid) on callus induction was investigated. It was found that growth regulators and their concentrations have obvious effects on the
