Connective Tissue
Human Anatomy - Supporting Connective Tissue - Cartilage + Bone
Question | Answer |
---|---|
hyaline cartilage - structure | structure - glassy-appearing matrix; lacunae house chondrocytes; tissue usually covered by perichondrium |
fibrocartilage - structure | structure - readily visible, parallel collagen fibers in matrix; lacunae house chondrocytes; no perichondrium |
elastic cartilage - structure | structure - contains abundant elastic fibers; elastic fibers form weblike mesh around lacunae; perichondrium present |
hyaline cartilage - function | function - smooth surface for movement at joints; model for bone growth; supports soft tissue |
fibrocartilage - function | function - resists compression; absorbs shock in some joints |
elastic cartilage - function | function - maintains structure and shape while permitting extensive flexibility |
hyaline cartilage - location | location - most of fetal skeleton; covers articular ends of long bones; costal cartilage; larynx, trachea, nose |
fibrocartilage - location | location - intervertrebral discs; pubic symphysis; menisci of knee joints |
elastic cartilage - location | location - external ear, epiglottis of larynx |
compact bone - structure | structure - calcified matrix arranged in osteons (concentric lamellae arranged around a central canal containing blood vessels) |
spongy bone - structure | structure - lacks organization of compact bone; contains macroscopic spaces; arranged in a meshwork pattern |
compact bone - function | function - supports soft structures; protects vital organs; provides levers for movement; stores calcium and phosphorus |
spongy bone - function | function - supports soft structures; protects vital organs; provides levers for movement; stores calcium and phosphorus; site of hemopoiesis |
compact bone - location | location - bones of body |
spongy bone - location | location - bones of body |
