The type and arrangement of extracellular fibers will dictate what?
The strength, permeability, and function of a connective tissue.
Which CT has relatively few fibers, primarily type I collagen, and more ground substance?
Loose (areolar) CT
How are the fibers of Loose CT compared to Dense CT?
Loose is more cellular (more cells and less extracellular matric)
Loose has thin fibers compared to thick bundles in dense CT.
Which tissue surrounds blood and lymph vessels and glands and lies under the lamina propria?
Loose CT
Which CT is permeable to oxygen, water, and other molecules?
Loose CT
Which CT include cells of the immune system that fight off foreign material that breach the epithelial barrier?
Loose CT
Which CT contain type I collagen?
Loose, Dense irregular, and Dense regular?
Which CT has extracellular fibers that form thick,irregular, and eosinophilic bundles?
Dense irregular CT
Which CT has cells that are sparse?
Dense irregular CT
Which CT is found in organs and tissues that are normally subjected to stresses from varying directions?
Dense irregular CT
The dermis of the skin and the submucosa (layer in the walls of hollow organs such as intestine) contain what type of CT?
Dense irregular CT
Which CT has densely packed, parallel, eosinophilic bundles?
Dense regular CT
Cells of CT are called?
Fibroblasts
What type of CT is found in ligaments, tendons, and aponeurosis?
Dense regular CT
What CT is type III collagen?
Reticular tissue
What CT is too thin/mesh-like to be seen in H&E sections?
Reticular tissue
Silver stains, which stain tissue brown or black, is used to stain what type of CT?
Reticular tissue
Which CT provides structural support (stroma) for many organs that are not part of the alimentary canal (liver, kidney, and lymph)?
Reticular Tissues
Which CT has a mesh-like pattern that permits passage of cells and other material through the organ?
Reticular Tissue
Tissues that are refractile (appear white) in H&E?
Elastic Tissues
Which tissue stain with eosin, but not as well as collagen fibers?
Elastic Tissue
How are the fibroblasts arranged in elastic tissues than the dense regular CT?
More randomly arranged
Nuchal ligament or ligaments in which elasticity is important is made from what CT?
Elastic
What tissue is present in muscular and elastic arteries?
Elastic lamellae
What tissues are thin sheets interspersed with smooth muscle?
Elastic lamellae
What tissue is synthesized by smooth muscles (no fibroblasts needed)?
Elastic lamellae
Large aggregation of adipocytes are referred to as?
Adipose tissue
What structure has a thin rim of cytoplasm surrounding a large, unstained lipid droplet. The nucleus is at the perimeter, giving the cell a "signet ring" appearance
Adipose tissue
Which cells synthesize the fibers and ground substance of CT?
Fibroblasts
What cells store neutral fats and produce hormones and have an unilocular (signet ring appearance)
Adipocytes
What are the immune cells?
Mast, Macrophages, Lymphocytes, Plasma, and White Blood Cells
What cell has cytoplasm that is filled with granules with contain mediators (such as histamines)
Mast cells
What cell does phagocytosis and is an antigen-presenting cell?
Macrophages
Which cell requires special preparation in order to distinguish it in LM sections?
Macrophages
What cell has a high nucleus to cytoplasm ratio and is basophilic?
Lymphocytes
Which cell has condensed chromatin, large golgi near nucleus (unstained region), and basophilic cytoplasm
Plasma cells
Neutrophils and eosinophils are what type of cells?
White Blood Cells
