| 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 |
