Study Notes
Connective Tissue
- Most abundant tissue in the body
- Supports and binds tissues together
- Rich blood supply except for cartilage which is avascular
- Does not occur on free surfaces of organs
- Contains widely scattered cells
- Contains intercellular material called matrix
- Functions include protection, support, and binding organs together.
Cells of Connective Tissue
- Produce the intercellular substance that determines the tissue's qualities
- Intercellular substance can be fluid, semi-fluid, mucoid, or fibrous
- Connective tissue cells store fat, ingest bacteria and cell debris, form anticoagulants, and produce antibodies
Types of Connective Tissue
Embryonic Connective Tissue
- Mesenchyme
- Mucous Connective Tissue (Wharton's Jelly)
Adult Connective Tissue
- Connective Tissue Proper
- Loose (areolar) connective tissue
- Adipose tissue
- Dense (collagenous) connective tissue
- Elastic connective tissue
- Reticular connective tissue
- Cartilage
- Hyaline cartilage
- Fibrocartilage
- Elastic cartilage
- Osseous (bone) tissue
- Vascular (blood) tissue
Mesenchyme
- Found exclusively in the embryo.
- The origin of all other connective tissues
- Found beneath the skin and along developing bones
- Mesenchymal cells differentiate into fibroblasts in blood vessels
Mucous Connective Tissue (Wharton's Jelly)
- Found in umbilical cord
- Has a thick consistency that can impede drug movement.
Loose Connective Tissue Cells
- Fibroblasts - Large, flat, branching cells that form collagenous and elastic fibers and ground substance when tissue is injured.
- Macrophages - Irregular, short, branching cells derived from white blood cells called monocytes. Engulf bacteria and cellular debris by phagocytosis.
- Plasma Cells - Small, round or irregular cells derived from lymphocytes. Produce antibodies for the immune system. Found in connective tissue of digestive tract and mammary glands.
- Mast Cells - Derived from basophils. Produce heparin (anticoagulant), histamine, serotonin, and chemicals that dilate small blood vessels.
- Melanocytes (Pigment Cells) - Produce melanin.
- Adipocytes (Fat Cells) - Derived from fibroblasts. Contain a large droplet of fat that pushes the cytoplasm and nucleus to the edge of the cell.
- Leucocytes (White Blood Cells) - Found in loose connective tissue.
Adipose Tissue
- A type of loose connective tissue that specializes in fat storage.
- Found beneath the skin, around the kidneys, at the base and on the surface of the heart, in the marrow of long bones, as padding around joints, and behind the eyeball.
Dense (Collagenous) Connective Tissue
- Close packing of fibers
- Fibers irregularly arranged where tension is exerted in various directions
- Fibers regularly arranged where tension is exerted in one direction
- Less intercellular substance than in loose connective tissue
Dense Irregular Connective Tissue
- Found in fasciae, the reticular dermis of the skin, the periosteum of bone, the perichondrium of cartilage, and membrane capsules around kidneys, liver, testes, and lymph nodes.
Dense Regular Connective Tissue
- Predominantly collagenous fibers arranged in bundles
- Fibroblasts are placed in rows between bundles
- Silverly white, tough, yet somewhat pliable
- Principal component of tendons, ligaments, and aponeuroses.
### Elastic Connective Tissue
- Predominantly freely branching elastic fibers
- Yellow color
- Stretchable and snaps back into shape
- Provides stretch and strength
- Found in cartilages of the larynx, walls of elastic arteries, trachea, bronchial tubes, and lungs.
### Reticular Connective Tissue
- Interlacing reticular fibers
- Forms a delicate supporting stroma for many organs (liver, spleen, lymph nodes)
Cartilage
- Connective tissue enduring more stress than other connective tissue types
- Avascular and lacks nerves
- Consists of a dense network of collagenous and elastic fibers
- Mature cartilage cells are called chondrocytes.
