Chapter 4 Study Guide Bio 169 • Individual body cells are specialized -Each type performs specific functions that help maintain homeostasis • Tissues are groups of cells that are similar in structure and perform a common function • Histology – study of tissues PRIMARY TISSUE TYPES: 1) Epithelial Tissue (or epithelium) is a sheet of cells that covers a body surface or lines a body cavity Forms boundaries Occurs in the body as covering and lining epithelium and glandular epithelium

Types of Tissues Stacy Sisler HS 120‚ Section 03 Unit 2 Seminar Kaplan University Jan. 17‚ 2011 Types of Tissue A tissue is a group of cells that have a similar shape and function. Different type of tissues can be found in different organs. In humans‚ there re four basic types of tissue: epithelial tissue‚ connective tissue‚ muscular tissue‚ and nervous tissue. There may be various sub-tissues within each of the primary tissues. Epithelial tissue covers the body

Classification of Tissues Introduction Cells are the smallest units of life. In complex organisms‚ cells group together with one another based on similar structure and function to form tissues .Tissues provide the numerous functions of organs necessary to maintain biological life. This lab exercise seeks to introduce the various tissues found in the human body and to familiarize you with their composition and function. The study of tissues is called histology ‚ and is important to the understanding

Epithelial tissue Covers the body surface and forms the lining for most internal cavities. The major function of epithelial tissue includes protection‚ secretion‚ absorption‚ and filtration. The skin is an organ made up of epithelial tissue which protects the body from dirt‚ dust‚ bacteria and other microbes that may be harmful. Epithelial tissue covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers. This tissue is specialised to form the

Histology This lab focused on the examination and identification of tissues that make up the organs of the body. The tissues are divided into four main categories: epithelial‚ connective‚ muscle‚ and neuronal. Click on the thumbnail images to see a larger version. All of the photomicrographs were taken using the 40X objective (400X magnification)‚ which is the highest magnification we use in this lab. Other resources include linked web pages on the "Resources" page and the histology tutorial

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.

There are three different types of epithelial tissues that are found inside the human body. There is the cutaneous membrane (tissue)‚ which we would refer to as “skin”. This part is the only epithelial tissue that is touched by air and is dry. The cutaneous membrane is composed of keratinizing stratified squamous epithelium. The second is the mucous membrane‚ which is the tissue used for absorption and secretion‚ protective lubricating mucus in the repertory and digestive system. This membrane

Tissue Types Amy Chanda Morrison Colorado Christian University Our bodies have four different types of tissues. They are epithelial‚ connective‚ muscle and nervous. Each one has a specific job to do to keep the body in homeostasis. Patton stated “homeostasis is the relatively constant state maintained by the body” (pg.19). He also stated that “the precise and constant chemical composition of the internal environment must be maintained within very narrow limits‚ or sickness and death will result”
