types of tissue found in animals: connective‚ muscle‚ nervous‚ and epithelial. We are going to go into muscle tissue. The cells of muscle tissues are called fibers. There are three types of muscle tissue and they are skeletal‚ cardiac‚ and smooth. All types can go though hypertrophy (enlargement or overgrowth of an organ or part of the body due to the increased size of the constituent cells). Muscle fibers contract due to the interaction of the contractile proteins‚ actin and myosin. Muscle contraction

Stratified Squamous Epithelium (left side) Flat epithelial tissues which are flat and have more than one layer. The Skin for a barrier. Your skin‚ for example‚ is a formidable barrier against many things. Skin is created when the basal cells in skin are dividing by the process of mitosis and‚ as division takes place‚ the cells get pushed upwards. As a result‚ the newer cells tend to stay near the bottom of the epithelial tissue‚ and the older cells get pushed upward and eventually

Background: Connective tissue nevi (CTN) are hamartomas in which components of the dermis (collagen‚ elastin‚ or glycosaminoglycans) are altered. Appear as firm‚ asymptomatic‚ skin-colored plaques composed of closely grouped papules with an orange peel-like surface texture. Previous classifications made based on which dermal component was found in excess‚ genetic patterns of inheritance‚ and +/- organ involvement fail to explain all reported cases. o Example: Buschke-Ollendorff syndrome

Stratified squamous: A stratified squamous epithelium consists of squamous (flattened) epithelial cells arranged in layers upon a basal membrane. Although this epithelium is referred to as squamous‚ many cells within the layers may not be flattened; this is due to the convention of naming epithelia according to the cell type at the surface. In the deeper layers‚ the cells may be columnar or cuboidal. This type of epithelium is well suited to areas in the body subject to constant abrasion‚ as it

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.
