Name one of the two major proteins in thistissue32. The 'Explanation' is available only after the question is attempted. In addition to some fibroblasts and a few delicate collagen fibers, you should see quite a few plasma cells amongst the epithelial tubes is also a very good specimen to examine the pseudostratified, ciliated columnar epithelium of the trachea. Name the structure designated by the arrows14. 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. Fibroblasts and adipocytes do not leave connective tissue.

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. What are the secretory products of the mast cell? You can see one large lipid droplet in the cytoplasm of each cell. Where are the nuclei of the fat cells? Note how the diameter of the fibers varies with location. Dense regular, dense fibrous or white fibroustissue4. Then use your text and atlas to review the diagnostic features of each connective tissue cell present in the micrograph.

The quiz does not provide comprehensive coverage of the contents of this site. Mesenchyme Mesenchyme is an early form of connective tissue found in embryos. The composition of these elements is the basis of which connective tissues are classified. Many of the free cells in these medullary sinuses cannot be identified; however, the large rounded cells, with eccentrically placed, vesicular nuclei are the ones you should try to find. Name the structure designated by the arrow4.

Many of the major types of cellular organelles are visible in this image. In this area note the irregular, wavy collagen fibers arranged singly or in small groups. Even though we try to set up rigid categories e. Plasma cells may also be found within the connective tissue of many of the glands that secrete into these regions. Locate the large clear circles in the connective tissue that sits beneath the epithelium. The collagen of fibrous supporting tissues, the dermis of the skin, tendon, ligaments and bone is type I collagen, which provides tensile strength. A 'Hint' is available before answering the question.

The antibody binds mast cells and waits for a second exposure to whatever it happens to be responsive to an allergen. Note the paucity of collagen fibrils. Use the quiz to test your basic histological know-how, know-what and no-where. Fibroblast Fibroblasts are widely distributed within connective tissue and synthesize the components of the extracellular matrix. On slide 27 look at the accumulations of darkly stained cells lymphocytes in a lymph node.

Name the structure designated by the arrow40. You should be able to recognize a range of nuclear morphologies and be able to identify the cells as fibroblasts. Taking a histology practice quiz will help you get a high grade in your histology class or anatomy class.

. In the nucleus, areas of euchromatin and heterochromatin can easily be identified. However, as seen in this slide, it is quite normal to find them in tissues such as the gut where foreign substances frequently invoke an inflammatory response. The degranulation of these cells is responsible for triggering type I, immediate hypersensitivity reactions. IgE is an antibody, produced by plasma cells, that has a high affinity for mast cells and basophils. Neutrophils can be identified by their granular cytoplasm and their multilobular, condensed nuclei. This will lead the way to get your medical degree, nursing degree, or other healthcare degree! Name the structure designated by the arrow22.

Epithelial Tissue

Recall that the primary function of plasma cells is antibody secretion, so they are a prominent constituent of loose connective tissue wherever antigens may enter the body, such as the gastrointestinal, urogenital, and respiratory tracts. Macrophages are avidly phagocytic cells that engulf and digest microbes, cellular debris and foreign substances. Web Histology Quizzes-Connective Tissue Click here to add to your favorites so that you can take a histology practice quiz throughout your histology class. They are also capable of differentiating into other types of connective tissue cells. Subcutaneous fat, surrounding visceral organs17. Look for adipose tissue in Slide 30 which is taken from abdominal mesentery the connective tissue that suspends the viscera within the abdominal cavity. They may occur singly but are more often found as clusters within loose connective tissue.

Kidney tubules, lining the ducts of many glands 32. Macrophages can be seen also in the subcapsular sinus the lighter staining area just under the capsule at the periphery of the lymph node. What is the physiological state of the cellsdesignated by the arrow? Access to the supplemental resources for this session is password-protected and restricted to University of Michigan students. The very small cracks between the fibers are just artifacts of shrinkage that occured during tissue preparation. Neutrophils and macrophages are also present and both are discussed below. Many of these macrophages contain phagocytosed red blood cells or the brownish breakdown pigment, hemosiderin which is the result of lysosomal action on the ingested red blood cells. None of our slides of adult tissue shows any brown fat, however this rather unique tissue can be seen in slide H2 , which is from a developing fetus.

They are round to oval shaped cells with a distinct cell boundary and a nucleus set to one side. If you have selected a large number of subject areas it may occasionally take a few seconds for the question to be set. However, to see the mast cells, you will need to look deeper in the submucosa where you should find small, ovoid cells amongst the collagen fibers with spherical, eccentric nuclei and intensely basophilic dark purple to black granules. The collagen has an associated carbohydrate moiety uncharacterized that can reduce Ag+ to metallic Ag revealing a network reticulum of fine, black fibrils. It has three primary components: fibers, extracellular matrix and cells.
