Histology Lecture (Connective tissue) part 1 Flashcards
Support and bind tissues for all organs.
Connective Tissue
Provide packing tissue between organs.
Connective Tissue
Creates a hydrophilic environment.
Connective Tissue
Mediates exchange of substances b/w
blood and tissues.
Hydrophilic Environment
Mesodermal in origin.
Connective Tissue
Origin of connective tissue.
Mesoderm
Embyonic tissue.
Mesenchyme
Origin of different tissues w/c develop into
specialized cells of adult tissue.
Mesenchyme
Example of adult tissue that developed from mesenchyme.
- Connective Tissue
- Smooth Muscles
- Blood Cells
6 Main functions of Connective Tissue.
- Structural framework for the body.
- . Protection/mechanical support for all organs and tissues.
- Transport fluids and dissolves substances.
- Storage of energy.
- Protection of the body against infection.
- Significant role in repair or healing of wounds.
Composition of Connective Tissue
- Connective Tissue Cells
- Extracellular Matrix
2 types of connective tissue cells.
- Fixed Cells
- Free Mobile or Wondering Cells
Produce and maintain extracellular components and storage of reserve fuel.
Fixed Cells
5 cells under classified as fixed cells.
- Fibroblast
- Fixed Macrophages
- Adipose Cells
- Reticular Cells
- Undifferentiated Mesenchymal Cells
For short term tissue reaction to injury.
Free Mobile or Wondering Cells
5 cells under classified as free mobile or wondering cells.
- Macrophages
- Plasma Cells
- Mast Cells
- Eosinophils
- Lymphoid Cells
Bone marrow in origin.
Mast Cell
Produce Histamine.
Mast Cell
Help dilate small blood vessels in reaction to injury.
Histamine
3 compounds released by mast cell, which are involved in inflammatory responses.
- Heparin
- Histamine
- Chemical mediators
Inflammatory response cell/mast cell in liver.
Kupffer Cells
Inflammatory response cell/mast cell in CNS.
Microglia I cell
Inflammatory response cell/mast cell in bone.
Osteoclasts
Store triglycerides, support, protect and insulate.
Adipocytes
______________ store energy in the form of ______________.
- fat cells
- triglycerides
Activated form of fibroblasts.
fibroblasts
Inactivated form of fibroblasts.
Fibrocytes
Flat with fine granular cytoplasm.
Fibroblasts
Secrete both fibers and ground substance of the matrix.
Fibroblasts
Phagocytes that develop from Monocytes.
Macrophages
ECM turn over.
Macrophages
Phagocytosis of dead cells or debris.
Macrophages
Takes part in the antigen presentation to lymphocytes.
Macrophages
Shape of the nucleus of Macrophages.
oval and kidney-like
