Study Notes
Tissue Conjonctif
- A type of supportive tissue that provides a framework for other tissues and organs to function properly.
Definition
- Structurally, composed of cells, fibers, and a fundamental substance that provides a framework.
- Functionally, fills the space between organs and tissues, providing a connection and support system.
Embryonic Origin
- Originates from the mesoblast, a type of embryonic tissue.
- Mesoblast differentiates into mesenchymal cells, which then differentiate into various types of cells.
Characteristics
- Star-shaped cell structure with cytoplasmic extensions.
- Semi-solid substance that provides a framework.
- Functional role in providing a connection and support system.
Functions
- Crucial role in connecting organs and tissues, providing a framework.
- Provides a pathway for nutrients and waste products.
- Plays a role in the immune system, providing a defense against pathogens.
Pathological Role
- Plays a significant role in inflammation, a response to tissue injury or infection.
- Inflammation involves the activation of various cells and molecules, including macrophages, lymphocytes, and cytokines.
- Affected by inflammation, leading to changes in its structure and function.
Classification
- Classified into different types based on the presence of certain cells and fibers.
- Main types: Fibroblastic, Chondroblastic, and Osteoblastic Tissue Conjonctif.
Histological Study
- Studied using histological techniques, such as staining and microscopy.
- Most common staining technique: H&E (Hematoxylin and Eosin) stain.
Cell Types
- Composed of various cell types, including:
- Fibroblasts: produce collagen fibers.
- Chondroblasts: produce cartilage fibers.
- Osteoblasts: produce bone fibers.
- Macrophages: play a role in the immune system.
- Lymphocytes: play a role in the immune system.
- Mast cells: play a role in the immune system.
- Giant cells: formed by the fusion of multiple macrophages.
Fibroblasts
- Important cell type in connective tissue.
- Function: produce fibers and substance fundamental to form connective tissue.
- Characteristics: star-shaped or fusiform, nucleus is not mytotic, cytoplasm is basophilic, RER is well-developed, and synthesizes proteins for fibers and substance fundamental.
- Role: in immune response, synthesizes cytokines for inflammation and immune response.
Adipocytes
- Specialized cells for storing fat.
- Two types: primary (brown fat) and secondary (white fat).
- Primary Adipocytes: polygonal shape, nucleus is central, multiple lipid vacuoles, multiple mitochondria, and function to produce heat.
