Tissues

• Diversity in lamina layers is simple and stratified, and function varies in terms of shapes such as squamous, cuboidal, columnar.
• Lamina layers can be lined and covered by body surfaces and body cavities, forming mesothelium (body cavities) and endothelium (blood vessels).
• Basal lamina is a membrane basement membrane, resting outside the cell, and is the resting extracellular lattice.
• Endymal cells range in shape from squamous to columnar and many are ciliaated to produce cerbrospinal fluid.
• Astrocytes function to support and brace neurons and blood vessels, and guide the migration of young neurons.
• Microglia are small, void cells that process and monitor the health of neurons.
• Renewal is the process of closing to the basement lumen, resulting in continuous renewal.
• Types of Adipose Tissue include white/unilocular, containing a single fat drop with a regular appearance, and brown/multilocular, containing multiple small lipid drops with a richer mitochondria.
• Adipocytes usually come from blood or bone marrow, and are usually found in the subcutaneous tissue.
• Macrophage (histiocytes) is the most numerous type in lost connective tissue, and contains estimated material in cytoplasm.
• Adispose or adipocytes can store fat permanently, and the cells' permeability allows permanent tissue issues to be resolved.
• Avascularity is rarely penetrated by blood vessels, making epithelia issues not exhibit blood in it.
• Cell packing is with very little intercellular space, joined by specialized junctions, and is very close to each other.
• Adult Mesenchyme retains some unfferentiaed cells and is a reserve population for the creation of new cells.
• Embryonic Mesenchyme loses network of cells and is reduced to a uniform matrix.
• Dense irregular connective tissue is densely packed with regular and parallel arrangement of fibers.
• Mesenchymal cells are the source of most connective tissues.
• There are two types of Mesenchymal Cells: Embryonic Mesenchyme and Adult Mesenchyme.
• Dense irregular connective tissue consists of fibers that are irregular and random oriented.
• The location of dense irregular connective tissue is the regular layer of dermis.
• The cells of dense irregular connective tissue are native to the tissues where they are found.
• Endomysium (fiber) - Composition: Loose connective tissue with blood vessels, nerves, and satellite cells which function in the repair of muscle.
• Derivation is into endoderm, mesoderm, and ectoderm classifications.
• Collagen fibers have bands, loops, and zigzags.
• Collagen fibers are single cells, not called fibers, with one to two nuclei at the center.
• Collagen fibers exhibit regular arrangements of actin and myosin.
• Collagen fibers are located in the walls and septa of heart chambers, and in the walls of large vessels.
• Collagen fibers are found in the endomysium, perimysium, and epimysium.
• Collagen fibers have a characteristic of one or two nuclei; shorter and branched.
• Collagen fibers have repeating cross-strands.
• Below the cells, there are spicules of calcified cartilage that are surrounded by a layer of osteoblasts.
• Origin of cells is different from antibody-stimulated B lymphocytes.
• These cells have large nuclei and are abundant in the cytoplasm.
• epiphyseal plate is a specific cartilage that covers the ends of long bones from ossifying.
• These cells have large nuclei and are abundant in the cytop
• Hyaleine cartilage is surrounded by a layer of osteoblasts.
• Characteristic of these cells is that they have large, ovoid cells with eccentric nuclei, abundant RER, and condensed chromatin.
• A layer of osteoblasts is formed around the hyaleine cartilage as it ossiifies.
• Hyaleine cartilage matrix contains producing hypertrichoid chondrocytes below the cells.
• Epiphyseal plate is a blank region
