Identify the preparation eg:Thick skin Type of evaluation questions: identify this structure Give the name of the structure eg: subastonouis gland gland, exocrine, tubular, simple, with one identify and classify this structure completely extrectory duct and coiled ** Carotenoide (tres oranger noir is hard to adhere to epithelium so white line. Only in the skin Contains loosely arranged fibers (collagen type1) and more ground substance. It provides 2 **Irregular** support while allowing flexibility and is found in areas like beneath epithelial tissues **Loose Connective Tissue** Contains fibers arranged in a regular pattern, **Regular** often found in pacinie carpuscule Provides structural support to various organs Support (e.g., cartilages, tendons, capsules) and tissues. Fibers are densely packed but irregularly **Types of Connective Tissue** 2 arranged, providing strength in multiple **Irregular** Contains cells like phagocytes (e.g., macrophages) that directions, such as in the dermis of the skin Defense/Protection (e.g., phagocytic cells) protect the body by engulfing pathogens and debris **Dense Connective Tissue** Fibers are densely packed and regularly aligned, Adipose tissue (fat) stores energy in the form of not in evaluation 1 giving strength in one direction, such as in **Regular** **Connective Tissue** **Functions** Storage (e.g., adipose tissue) lipids tendons and legaments Acts as a medium for the exchange of nutrients, 2 white adipose tissue Cell predominance, very vascularize tissue Adipose Tissue Exchange/Communication waste products, and gases between cells and the blood Cartilaginous Tissue **Special Types** Plays a crucial role in wound healing through the Healing regeneration of cells and tissue remodeling Bone Tissue (Ossification) Connective Tissue Actively synthesize the extracellular matrix, including collagen. They are **Fibroblasts** Histology Class A gel-like material that fills the space between cells and fibers, aiding in the diffusion of fusiform in shape with an ovoid, well-defined nucleus Mindmap nutrients and waste products. These are the inactive form of fibroblasts, typically found in **Fibrocytes** Long unbranched polysaccharides. Examples include heparin connective tissue when there is little ECM synthesis **Ground Substance** Glycosaminoglycans (GAGs) (anticoagulant) and hyaluronic acid (important in tissue hydration and repair) Store fat **Adipocytes** Made of a core protein with GAGs attached. Examples include play a critical role in inflammation and allergic responses contains important molecules like Proteoglycans aggrecan and decorin, which help maintain the structure of the ECM **Mast Cells** Contains granules that store heparin (anticoagulant) and histamine (inflammatory mediator) **Components** **Extracellular Matrix (ECM)** These proteins help in cell adhesion and interaction with the ECM. Glycoproteins Examples are laminin (found in the basement membrane) and chondronectin (in cartilage) engulfing and digesting pathogens, dead cells, and debris **Macrophages** Strong, flexible, and abundant, especially in tissues like tendons Derived from monocytes Collagen fibers and ligaments. Reticular fibers (a subtype) are thinner and form **Cells** networks supporting organs. Includes collagen, elastic, and reticular fibers derived from lymphocytes and are critical in the **Fibers** that provide tensile strength and elasticity. immune system Composed of elastin and microfibrils, these fibers provide **Plasma Cells** Elastic fibers elasticity to tissues, such as in skin and arteries rich in rough endoplasmic reticulum (RER), allowing for the production of antibodies involved in regulating blood flow and repairing tissues **Pericytes** Contain myosin in the cytoplasm, allowing them to contract and influence blood flow. **Leukocytes** (white blood cells) Multipotent stem cells: They can differentiate into various specialized cells like **Mesenchymal Cells** fibroblasts, adipocytes, osteocytes (bone cells), and chondrocytes (cartilage cells)
