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

Epithelia form the surface of the skin‚ line the various cavities and tubes of the body‚ and cover the internal organs. Subsets of Epithelia Epithelia that form the interface between the internal and external environments. Skin as well as the lining of the mouth and nasal cavity. These are derived from ectoderm.

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

ANIMAL TISSUES 1. Classify the animal tissues. On the basis of the function they perform‚ animal tissues are classified into four different types. They are: i) Epithelial tissue ii) Connective tissue iii) Muscular tissue iv) Nervous tissue 2. What are epithelial tissues? What are the characteristic features of these tissues? The covering or protective tissues in the animal body are called epithelial tissues. They also perform the functions of secretion and absorption

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 callus induction‚ the increment of callus index and callus physical appearance. The best callus induction capabilities were obtained with low levels of NAA However‚ supplemented medium with high concentrations of NAA led to relatively low callus frequency and the

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

Muscle tissue Muscle tissue has a ability to relax and contrast and so bring about movement and mechanical work in various parts of the body. There are other movements in the body too which are necessary for the survival of the organism such as the heart beat and the movements of the alimentary canal. Muscles can be divided into three main groups according to their structure * Smooth muscle tissue. * Skeletal muscle tissue. * Cardiac (heart) muscle tissue.
