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

QUILONA‚ KLARISSE JANE A. BSP-1B Animal Tissues 1. Epithelial Epithelial tissue is made of closely-packed cells arranged in flat sheets. 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. Inner lining of the GI tract‚ lungs‚ urinary

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

Types of epithelial tissue Connective tissue -Connective tissues are fibrous tissues. They are comprised of cells separated by non-living material‚ which is called extracellular matrix. Connective tissue holds other tissues together such as in the formation of organs‚ and has the ability to stretch and contract passively. Bone‚ often referred to as osseous tissue‚ and blood are examples of specialized connective tissues. Conective tissues are cells that are suspended in a matrix of their own secretions

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”

2010 ANATOMY AND PHYSIOLOGY I Chapter 4: TISSUES AND MEMBRANES Outline of Notes I. Introduction. A. General: Cells are highly specialized and interdependent on one another. Groups of similar cells performing similar functions are called Tissues The study of tissues is called Histology. Organs are made of tissues. A detailed understanding of tissues will greatly help your understanding of organs and organ systems later in this course. Tissues are classified into 4 main types:

The lungs are made up of many types of tissue; the cartilages‚ ciliated epithelium‚ smooth muscle‚ squamous epithelium‚ elastic fibres and goblet cells and glandular tissue. The cartilage is a very stiff and flexible tissue‚ which doesn’t contain air vessels. It is found in trachea‚ bronchus‚ bronchiole and alveolus‚ and it has a structural role. It support‚ and gives strength to trachea and bronchi. It holds the airways open for the resistance with little airway. This prevents it from collapse

Polymethylmethacrylate‚ or PMMA for short‚ is a polymer consisting of the monomer methyl methacrylate that has been around since the 1930s1. PMMA is a polymer that has a high impact strength‚ is scratch and shatter resistant‚ and is relatively lightweight1. Because PMMA can also be formed into a transparent thermoplastic and has a glass transitions temperature of 130oC‚ this polymer served as a glass substitute in its early uses1. Other beneficial characteristics of Polymethylmethacrylate include

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
