What is the skeletal system composed of
Cartiladge, bones and ligaments
cartilage
-shock absorption,smooth joint movements
What are ligaments
connection between the bones
Attaches bone tobone
constrains skeletal motion
What are tendons
connection between bones and muscle: connect bone to muscle
transfers muscle force to bone… generates motion
What are the lateral ligaments
Posterior talofibular ligament
anterior talofibular ligament
calcaneofibular ligament
Where is cartiladge found
ears
nose
articular cartiladge (between joints like knee)
costal cartilage (true ribs)
pubic symphysis
articular disk
What are chondrocytes
cartlidage cells
what are lacuna
space CONTAINING chondrocytes
is cartilage elastic
yes it is, it returns to its original state once compressed
cartiladge is a connective tissue?
Yes with extensive extracellular matric
NO nervous inervation or blood vessels
in cartiladge
What are the three types of cartilage
1) Hyaline
2) elastic
3) fibrocartilage
Hyaline cartilage
-flexible and resistant
-articular cartiladge
costal cartilage
respiratory cartligae
what two types of respiratory carilage
thyroid carlitage
cricoid cartilage
Elastic cartilage
found in epiglottis and outter (external ) ear
