Osteology Cartilage Flashcards
(3) types of cartilage. Describe. And what’s their Location? Hyaline cartilage
Hyaline cartilage:Glass like, most common, reduces friction -Articulate surface(where bones touch)
Fibrocartilige: Strongest, shock absorption, thick collagen Fibers- Pubis, spine, knees
Elastic cartilage: not common, stretches- epiglottis(ear)
Cartilage?
Avascular
Soft bone found throughout body
What are Osteoblasts, osteocytes,and osteoclasts.
Osteoblasts- build bones
Osteocytes-checks on bones, sends help, regulates
Osteoclasts- breaks down/gets rid of bones
What type of bone tissues are there? (2) discernible them.
Compact- outside, osteon
Spongy- deep to compact, trabecular
How many bones are there? What are the 4 categories of them all?
206,
- Long
- Flat
- Irregular
- Short
What does a compact bone do?
Outside of the bone, dense and solid. Stores deep to periosteum
Spongy bone
Deep to compact
End of long bones
Periosteum
Thin layer of dense connective irregular tissue that wraps around bone
Protects
Articular cartilage also knows as?
Hyaline cartilage, end of bones, reduces friction
Medullary cavity
Middle hole, yellow bone marrow is found here
Nutrient foramen
Hole or opening in bone for blood
Epiphysis
End of bone where spongy is located
Diaphysis
Shaft of the bone
What are chondrocytes?
Makes cartilage cells
Proteoglycans
Holds fibers together
Collagen vs elastic
Collagen-Tensile strength
Elastic- stretches coils and recoils
Similarities to other connective supporting tissues and differences from other connective supportive tissues?
S- Few cells lots of extra cellular matrix
D- rigid, solid, strong
What does strength to resist tension mean?
Strength to resist compression?
Ability to remodel or change?
You can’t pull apart
Cannot crush or compress
Allows changes
Inorganic components
Bone salts or minerals
Hydroxyapatite- hard stuff of bone
Osteon
Fundamental structural unit of compact bone
Spongy is also know. As?
Trabecular bone
Deep to periosteum?
Compact
Deep to compact?
Spongy
(6) functions of bone tissue and bones?
- Support
- Movement
- Protection
- Calcium homeostasis
- Blood-cell formation
- Energy storage
