Study Notes
Connective Tissue
- Protects and supports the body; binds body tissues together.
- Originates from the mesoderm.
- Components include fibroblasts, chondroblasts, adipocytes, macrophages, and leukocytes. Plasma is also a component.
Connective Tissue Components
- Collagen: Thickest and strongest fiber; provides strength and resistance. Found in tendons and ligaments.
- Reticular: Randomly oriented collagenous fibrils forming a meshwork; found in lymphatic tissues.
- Elastic: Contains elastin; returns to original state after stretching. Found in vascular walls.
- Extracellular Matrix (Ground Substance): Supports cells and determines tissue function. Composed of water, glycosaminoglycans, proteoglycans, and glycoproteins (polysaccharides). Maintains hydration and structural integrity.
Connective Tissue Classification
-
Connective Tissue Proper:
-
Dense Connective Tissue:
- Regular: Densely packed collagen in a parallel pattern; resists force in one direction (ligaments, tendons).
- Irregular: Collagen and elastic fibers in a random pattern; resists force in many directions (dermis of skin).
- Elastic: Many elastic fibers; stretch and recoil (arteries, bronchi).
-
Loose Connective Tissue:
- Areolar: Collagen and elastic fibers; anchors, binds, and supports organs (surrounds muscles and blood vessels). Found under the epidermis and around mucous membranes.
- Adipose: White adipose tissue (energy storage, 20-25% body weight); brown adipose tissue (generates heat).
- Reticular: Reticular fibers in a semi-solid matrix; supportive framework in lymphatic organs, liver, and bone marrow.
-
Dense Connective Tissue:
-
Specialized Connective Tissue (Supporting Connective Tissue):
-
Cartilage: Provides strength and elasticity.
- Elastic Cartilage: Many elastic fibers within the intracellular matrix (pinna of ear, epiglottis).
- Fibrocartilage: Dense, parallel collagen rows; resists compressive forces (temporomandibular joint).
- Bone: Compact and spongy bone; provides support and protection.
-
Cartilage: Provides strength and elasticity.
