Skeletal System 2 Cartilage Flashcards
Define Cartilage:
Dense + flexible connective tissue
The function of Cartilage:
support, cushion, absorb shock
The components of Cartilage:
gel-like matrix w/ collogen + elastic fibers
Collagen fibers are made by?
fibroblasts
Describe Hyaline Cartilage:
Firm matrix w/ collagen fibers
Most abundant form of cartilage in body
Function: supports + reinforces
Location: Long ends of bones, ribs, nose, trachea
Describe Elastic Cartilage:
firm matrix w/ elastic fibers
Function: flexibility
Location: external ear, epiglottis
Describe Fibro-cartilage:
firm matrix w/ thick collagen fibers
Function: Absorb shock
Location: Inteverterbral discs, knee
During pregnancy, the skeleton is FIRST made up of?
Hyaline Cartilage but is replaced by bones during adulthood
Define Articular Cartilage:
covers the ends of bones at joints
Define Costal Cartilage:
Connects the ribs to the sternum/breastbone
Define Laryngeal Cartilage:
Found in the voicebox
Define Tracheal/Bronchial Cartilage:
Supports the windpipe
Define Nasal Cartilage:
Cartilage that shapes the external nose
Define Intervertebral Discs:
Separates + Cushions the vertebrate
