Study Notes
Connective Tissue: Dense Regular
- Collagen fibers are arranged in parallel bundles, strengthening tissue and resisting tearing.
- Found in tendons, where collagen fibers fill the space between fibrocytes.
Connective Tissue: Reticular Tissue
- Made up of type III collagen (reticulin) forming a delicate network supporting cells.
- Reticular fibers produced by reticular cells (modified fibroblasts).
- Acts as a filter for interstitial fluid, lymph, and wandering cells.
Adipose Tissue: Triglycerides
- Triglycerides are stored in white adipocytes.
- Sources of triglycerides are: dietary fats, liver-synthesized triglycerides, and local synthesis.
- Dietary fats are transported by chylomicrons.
- Liver synthesized triglycerides are transported by very-low-density lipoproteins.
Adipose Tissue: White to Brown Transdifferentiation
- Mature white adipocytes can transform into brown adipocytes.
- Transdifferentiation is triggered by cold temperatures and physical exercise.
- Cold temperature stimulation increases sympathetic nervous system activity.
- Physical exercise stimulates the secretion of natriuretic peptides in the heart, activating transcription factors for brown adipocyte differentiation.
Cartilage: Hyaline
- Semirigid consistency due to bound water, acts as a shock absorber.
- Found in articular surfaces of movable joints, respiratory passages, and epiphyseal plates of long bones.
- Lacks vascular supplies and nerves, receives nutrients by diffusion from perichondrium.
- Matrix contains collagen, proteoglycans, and multiadhesive glycoproteins.
- Increases in size by appositional and interstitial growth.
- Does not calcify during the aging process.
Cartilage: Elastic
- Similar organization to hyaline cartilage but with abundant elastic fibers in the matrix.
- Provides greater flexibility.
- Found in the ears, epiglottis, and parts of the larynx
- Elasticity allows it to bend and recoil.
