Masson Trichrome and silver staining are frequently used in pathology to determine if connective tissue has proliferated--a sign of damage and attempted repair--in the liver, kidney and lung. Where is this tissue type found? Name the specific tissue found at the pointer. However the presence of a large number of cells from the or from epithelial cells in the kidney indicate urinary tract infection, high cholesterol, diabetes or kidney disease. D cartilage cells are surrounded by fluids. In these particular instances, don't worry so much about trying to exactly classify the tissue per se, but at least try to identify the cellular and extracelluar components that you can also bear in mind that you can't always definitely identify everycell and think how its overall appearance reflects its function.
Epithelium of bronchi is a Simple cuboidal b Glandular c Simple squamous d Pseudo stratified ciliated columar 7. Pseudostratified Columnar Epithelium Unfortunately, life isn't always as easy as we want it to be. Use these micrographs to review the structure of organelles. One of the places this tissue is found is in your bladder. Neutrophils and macrophages are also present and both are discussed below.
Brown fat is important for thermoregulation in newborns and hibernating mammals. In simple terms, transitional epithelial tissue is an elastic-like epithelial tissue that swells, contracts, and changes shape as necessary in order to accommodate something. Lining of intestine of man is a Brush bordered b Ciliated c Keratinized d Non keratinized 4. D size and location of cells. Name this specific tissue type.
The granules are often so dark that they obscure the nucleus. Be sure you can identify a macrophage and not just a bunch of cells superimposed upon one another. These cells secrete enzymes and play an important role in selectively absorbing digested food. Name the specific tissue at the pointer. For instance, the epithelium in a blood vessel demarcates the cells of the blood from those forming the artery or vein. Simple squamous epithelia are present where there is absorption or movement of materials.
Slide 250 which you used to look at stratified squamous non-keratinizing epithelium is also useful for the study of connective tissue we will also use this slide to study smooth muscle and peripheral ganglia. D into the brain tissue. All the cells in a pseudostratified epithelium interact with the basement membrane. Look for a region characterized by interlacing cords of cells. Name this specific tissue type. For maximum benefit it is advisable that a basic histology textbook be available for reference during this quiz.
Where might one find this epithelium? What surface specialization is seen? In this tissue section stained with aldehyde fuchsin and eosin, the structure indicated by the arrow is:. A areolar - loosely packed matrix of protein fibers B bone - mineralized matrix C cartilage - highly vascular matrix D blood - liquid matrix 49 Muscle tissue cells are contractile, which means they A are responsible for the production and secretion of enzymes. They are round to oval shaped cells with a distinct cell boundary and a nucleus set to one side. Macrophages are the biggest, rounded cells that are floating free in the spaces between the cords of cells. B are specialized in contraction and relaxation.
Where is this tissue found? Name this specific tissue type. Note that the nucleoplasm of a fibroblast has a generally fine stippled dot-like chromatin pattern with occasional coarse chromatin clumps heterochomatin and one or two nucleoli. Neutrophils can be identified by their granular cytoplasm and their multilobular, condensed nuclei. A single cell layer of epithelial tissue is called simple epithelial tissue, while stratified epithelial tissue is an epithelial tissue that is more than one cell layer thick. Similarly, the esophagus is also exposed to a wide range of different textures, pH levels and chemical compositions from food and drink. Where is this tissue found? On slide 27 look at the accumulations of darkly stained cells lymphocytes in a lymph node. Simple cuboidal epithelia line the lumen of collecting ducts in the kidney and are present in the thyroid around the follicles that secrete thyroid hormones.
These tissues often have a protective role, and the extent of friction or abrasion often determines the number of layers of cells. Name the structure at the pointer. Name the specific tissue at the pointer. Is this an indication of an active or inactive cell? C transitional and pseudostratified epithelium. Name the structure at the pointer.
The questions will indicate which ones are applicable to the unit and which ones are good things to know if you're reviewing the quizes before the midterm or final i. Chondrocytes are cells found in: the small intestine the heart the brain cartilage 8. The cross banding of the collagenous fibrils is easily observed. Type I reactions, also called anaphylactic reactions, are something you will learn about while studying the immune system later on, but for now, here is a quick explanation. C the intercellular material is missing.
B absence of any basement membrane. Transitional epithelia are a special subset of stratified epithelia that consist of ovoid cells that can stretch based on the pressure of liquids inside the organ. A protect the body B control the function of epithelial tissues C produce and secrete specialized compounds to control and maintain different body functions D help to maintain blood pressure and nerve actions 25 A carcinoma is a cancer originating from A epithelium B connective tissue C muscle tissue D nerve tissue 26 Which of the following is a function of epithelial tissue? Stratified Epithelium Stratified epithelia consist of more than one layer of cells and only one layer is in direct contact with the basement membrane. With the exception of the mouth and esophagus, the rest of digestive tract consisting of the stomach, small and large intestine is covered by these kinds of thin epithelia. Regardless of the shape, size, or arrangement of the cells, they are still a type of, or part of, epithelial tissue, just like all our differently sized, shaped, and arranged plastic bricks are still Legos. A cilia B Golgi apparatus C lysosomes D desmosomes 14 The lining of blood capillaries supplying body cells with oxygen and nutrients, are expected to consist of A connective tissue. Smooth muscle is found mainly in: the heart the stomach the brain the skeletal system 7.
