Connective Tissue
Loose Connective Tissue
- Forms lamina propria, supports overlying epithelium
- A lot of ground substance
- Fibroblasts, mast cells, macrophages and leukocytes
- Fewer collagen and elastic fibers
- Forms lamina propria, supports overlying epithelium
Dense Connective Tissue
- Regular
- Forms tendons, ligaments and apponeuroses
- Very little ground substance
- Fibroblasts, tendons and ligaments
- Collagen fibers in bundies arranged in parallel or osthogonally
- Forms tendons, ligaments and apponeuroses
- Irregular
- Forms capsules and submucosae (reticular layer of skin)
- Very little ground substance
- Fibroblasts and skin
- Collagen fibers in bundles with random orientation resists stretching
- Forms capsules and submucosae (reticular layer of skin)
- Regular
Specialised Connective Tissue
- Cartilage
- Chondrocytes are enclosed within the cavities present in the matrix ; provides flexibility
- Blood
- Fluid connective tissue and helps in transport of substances how to O2
- Bone
- Osteocytes are present within spaces "lacunae" ; provides support and protects the internal organs
- Cartilage
